1-2 Precautions

To ensure safe operation of the 3G3EV, note the following items:

Always Hold the Heat Sink During Removal. When moving the 3G3EV, always hold the heat sink (aluminum portion on the rear of the Unit).

Heat sink

Watch Out for Residual Voltage On Charged Portions After the power is turned off, residual voltage remains in the capacitor inside the Inverter. Therefore, touching terminals immediately after turning the power off may cause an electrical shock.

If an inspection or some other task is to be performed, always wait at least one minute from the time all indicators on the front panel go off.

(Note that this warning is applicable whenever you perform any task after turning the main circuit off.)

Do Not Remove the Digital Operator When the Main Circuit is Still On.

Always turn the main circuit off before removing the digital operator.

Removing the digital operator with the main circuit ON may cause an electrical shock and damage the equipment.

Chapter 1

Do Not Modify Wiring or Check Signals When the Main Circuit is On.

Always turn the main circuit off before modifying wiring or checking signals.

Touching terminals while the main circuit is on may cause an electrical shock and dam- age the equipment.

Do Not Conduct a Dielectric Strength Test. Because the 3G3EV Inverter is an electronic control unit using semiconductor, never conduct a dielectric strength test or an insulation resistance test for the control circuit.

Modify Constant Settings Correctly. Always modify the constant settings according to the procedures described in this manual.

Chapter 1

2-1 Features

Easy to Use

Basic Constants Displayed On Indicators Constants for basic operations such as frequency setting and acceleration/deceleration time setting are displayed on dedicated indicators. Therefore, constant numbers can be confirmed easily.

Easy to Install

Very Small and Lightweight The 3G3EV Inverter is approximately half the size of our Low-noise General-purpose Inverters in terms of volume and weight percentage. This improves space efficiency and operating efficiency (including easier removal).

Optional DIN Track An optional DIN track is available. This DIN track enables the user to mount the 3G3EV Inverter on the DIN track with a one-touch operation.

Chapter 2

Easy to Wire

Using Two-conductor Cables to Minimize Wiring Two-conductor cables (VCTF) enable the Inverter to be connected a higher-level PC.

Easy Wiring without Having to Open the Front Cover This Inverter can be wired just by opening the terminal block cover.

Separate Input and Output Terminal Blocks Power input terminals are located in the upper section, while motor output terminals are in the lower section. In this way, the input and output terminal blocks are separated ac- cording to the contactors, so incorrect wiring can be prevented.

Soldering No Longer Necessary No connector means no soldering.

Easy to Operate

Bitwise Communication Making Programming Easier No special communication program is required. Allocated input and output areas can be used to control the Inverter in a way similar to ordinary I/O Units.

Switching the Operation Mode by Simple Key Operation For example, after a test run is performed using the Digital Operator, it can be easily switched to a production run in communication mode by simple key operation.

Checking a Test Run with Various Monitors Output frequency, output current, and the direction of motor rotation appear in the dis- play section of the Digital Operator, so the mechanical system can be easily monitored during a test run.

Low Noise An insulated gate bipolar transistor (IGBT) power element has been adopted to elimi- nate metallic noise.

High-torque Operation Even in Low Speed Range A torque rate of 150% can be achieved even in a low speed range where output frequen- cy is only 3 Hz. Thus, acceleration time can be reduced.

Chapter 3

Ambient Temperature Control To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature rises.

If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50C.

The surface temperature of the Inverter may reach 30C higher than the ambient tem- perature. Therefore, keep all thermally susceptible devices and wires away from the Inverter.

Protecting the Inverter from Foreign Matter during Installation Place a cover over the Inverter to shield it from metal powder produced by drilling dur- ing installation.

(Upon completion of installation, always remove the cover from the Inverter. Other- wise, ventilation will be affected, causing the invert to overheat.)

3-2-2 Wiring Around the Main Circuit

System reliability and noise resistance are affected by the wiring method used. Therefore, always follow the instructions given below when connect- ing the Inverter to peripheral devices and other parts.

Wire Size and Molded-Case Circuit Breaker to be Used For the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables.

Chapter 3

)

If the cable is long and may cause voltage drops, increase the wire size according to the cable length.

Determining the Wire Size Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage.

Line voltage drop VD is calculated as follows:

VD (V) = 3 x wire resistance (/km) x wire length (m) x amperage (A) x 10—3

Wiring on the Input Side of Main Circuit

Installing a Molded-case Circuit Breaker Always connect the power input terminals (R, S, and T) and power supply via a molded- case circuit breaker.

Installing a Ground Fault Interrupter If a ground fault interrupter is to be connected to the wire on the primary side (R, S, and T) of the main circuit, use either of the following interrupters to prevent malfunctions:

Ground fault interrupter with a sensitivity amperage of 200 mA or more and with an operating time of 0.1 second or more

Ground fault interrupter with high-frequency countermeasures (for Inverter)

Chapter 3

Installing a Magnetic Contactor This Inverter can be used without a magnetic contactor (MC) on the power supply side.

If the power supply for the main circuit is to be shut off because of the sequence, a mag- netic contactor can be used instead of a molded-case circuit breaker.

However, when a magnetic contactor is installed on the primary side of the main circuit to forcibly stop a load, note that regenerative braking does not work and the load coasts to a stop.

A load can be started and stopped by opening and closing the magnetic contactor on the primary side. Note, however, that frequently opening and closing the magnetic contactor may cause the Inverter to break down.

When the Inverter is operated with a Digital Operator, automatic operation cannot be performed after recovery from a power interruption.

If a braking resistor unit is to be used, program the sequence so that the magnetic con- tactor is turned off by the contact of the units thermal relay.

Connecting Input Power Supply to the Terminal Block Because the phase sequence of input power supply is irrelevant to the phase sequence (R, S, T) of the terminal block, input power supply can be connected to any terminal on the terminal block.

Installing an AC Reactor If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advance capacitor is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down. To prevent this, install an optional AC reactor on the input side of the Inverter. This also improves the power factor on the power supply side.

Installing a Surge Absorber Always use a surge absorber or diode for the inductive loads to be connected to the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

Chapter 3

Installing a Noise Filter on the Power Supply Side Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

Wiring on the Output Side of Main Circuit

Connecting the Terminal Block to the Load Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.

Chapter 3

Never Connect Power Supply to Output Terminals

Caution Never connect a power supply to output terminals U, V, and W. If voltage is applied to the output terminals, the internal mechanism of the Inverter will be damaged.

Never Short or Ground the Output Terminals

Caution If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Also, be careful not to short the output wires.

Do Not Use a Phase Advance Capacitor or Noise Filter Never connect a phase advance capacitor or LC/RC noise filter to the output circuit. Do- ing so may result in damage to the Inverter or cause other parts to burn.

Do Not Use an Electromagnetic Switch Do not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is connected to the Inverter during operation, an inrush current will actuate the overcurrent protective circuit in the Inverter.

Installing a Thermal Relay This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi- polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set to 0.0 (no thermal protection) for constant No. 31 (THR indicator).

In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is turned off by the contact of the thermal relay.

Installing a Noise Filter on the Output Side Connect a noise filter to the output side of the Inverter to reduce radio noise and induc- tion noise.

Chapter 3

Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller to malfunction.

Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio receiver to make noise.

How to Prevent Induction Noise As described above, a noise filter can be used to prevent induction noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction noise.

How to Prevent Radio Noise Radio noise is generated from the Inverter as well as the input and output lines. To re- duce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.

The cable between the Inverter and the motor should be as short as possible.

Chapter 3

Cable Length between Inverter and Motor If the cable between the Inverter and the motor is long, the high-frequency leakage cur- rent will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in n37) as shown in the table below.

Cable length between Inverter and motor 50 m max. 100 m max. Carrier frequency (n37) 10 kHz max. (1, 2, 3, 4) 5 kHz max. (1, 2)

Ground Wiring Always use a ground terminal with a ground resistance of 100 or less.

Do not share the ground wire with other devices such as a welder or power tool.

Always use a ground wire that complies with technical standards on electrical equip- ment. Route the ground wire so that the total length is as short as possible.

When using more than one Inverter, be careful not to loop the ground wire.

5 m max.

1.25 mm2 min.

Chapter 3

Note Minimize the total length (5 m or less) between the ground electrode and the ground terminal, and also use a thick wire (1.25 m2 or more). Leakage current flows through the Inverter. Therefore, if the distance between the ground elec- trode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.

3-2-3 Wiring Control Circuit Terminals

The control signal line must be 50 m or less and must be separated from the power line.

Wiring Sequence Input/Output Terminals Wire the multi-function input1 terminals (S1 and SC) and the multi-function output 1 ter- minals (PA and PC) as described below.

Always connect the positive terminal to the positive terminal and the negative terminal to the negative terminal.

Wire the Remote I/O Master Unit (RM201) on the SYSMAC side first, then continue wiring in order. Set the last Slave Unit (device) as a terminator.

The overall cable length must be 200 m or less.

Always separate the transmission line from the main circuit cables and other power cables. In particular, the transmission line must not be parallel to or close to the output cables from the Inverter.

Do not connect a positive terminal to a negative terminal.

The Remote I/O Master Unit cannot be directly connected to more than one Remote I/O Slave Unit.

Wiring cannot be branched from a Remote I/O Slave Unit.

Chapter 3

)

3-2-5 Setting the Terminator

The Remote I/O Unit at the end of the system must be set as the terminator. Otherwise, all Remote I/O Units cannot operate. This section describes how to set the 3G3EV-AR as a terminator.

Setting the Terminator Open the terminal block cover in the lower part of the Inverter. The terminator setting switch is located on the left side of the control circuit terminals.

Sliding the switch to the right sets the Inverter as the terminator.

Terminator setting switch

Notes on Setting the Terminator The last Slave Unit under each Remote I/O Master Unit must be set as the terminator.

Always set a terminator even when only one unit is to be connected.

If no terminator is set, the Remote I/O System fails to operate, and the PC also fails to start operation even when the Master Unit enters run mode. In this case, the END RS indicator (terminator checking) remains lit. The Programming Console also displays a message indicating that CPU is on hold.

Unit of setting 0.1 (A)

This constant is used to set an electronic thermal reference value to protect the motor from overheating. Set the rated motor amperage in this constant.

If 0.0 is set in this constant, no thermal protection is assumed, so motor overload will not be detected.

The setting range and factory setting for this constant are as follows:

Stall Prevention during Deceleration Setting range 0, 1 Factory setting 0

This constant is used to select the action to prevent overvoltage during deceleration.

Value Description 0 Stall prevention during deceleration 1 No stall prevention during deceleration

Note 1. If a braking resistor is to be connected, always set 1 (no stall prevention during deceleration) in this constant.

Operation after Recovery from Power Interruption Setting range 0, 1, 2 Factory setting 0

This constant is used to select the processing to be performed after recovery from an instantaneous power interruption.

Value Description 0 Discontinues operation. 1 Continues operation only if power interruption is within 0.5 second. 2 Continues operation unconditionally (with no error output).

Note If 1 or 2 is selected to continue operation, the Inverter automatically searches the motor speed (even when the motor is in a free-running state) and continues smooth operation. This function is called the speed search function.

Carrier Frequency Setting range 1, 2, 3, 4 Factory setting 4 (10 kHz)

This constant is used to set a pulse-width-modulated (PWM) carrier frequency.

Value Carrier frequency 1 2.5 (kHz) 2 5 (kHz) 3 7.5 (kHz) 4 10 (kHz)

Chapter 4

Note As the cable between the Inverter and the motor becomes longer, a high-frequen- cy leakage current from the cable increases, causing the Inverter output current to increase as well. This may also affect peripheral devices. To prevent this, ad- just the carrier frequency according to the following standards:

Cable length of 50 meters or less: 10 kHz or less

Cable length of 50 to 100 meters: 5 kHz or less

Over-torque Detection Function Selection Setting range 0 to 4 Factory setting 0

Over-torque Detection Time Setting range 0.1 to 10

(seconds) Factory setting 0.1 (seconds)

Unit of setting 0.1 (seconds)

When excessive load is applied to the equipment, the Inverter detects any increase in output current and displays the fault according to the n09 and n10 settings (multi-func- tion output selection).

n50 is used to specify whether over-torque is to be monitored and specify the action to be taken when over-torque is detected.

n50 setting Description 0 Inverter does not monitor over-torque. 1 Inverter monitors over-torque only when speed is matched. It continues

operation (issues warning) even after over-torque is detected. 2 Inverter monitors over-torque only when speed is matched. It discontinues

operation (through protection function) when over-torque is detected. 3 Inverter always monitors over-torque during operation. It continues

operation (issues warning) even after over-torque is detected. 4 Inverter always monitors over-torque during operation. It discontinues

operation (through protection function) when over-torque is detected.

n51 is used to set the over-torque detection level. Specify this value in terms of the percentage of the rated output current.

n52 is used to set the over-torque detection time (in seconds).

When the output frequency drops below or exceeds the value set in n53, the Inverter displays the fault according to the n09 and n10 settings (multi-function output selec- tion).

To use the frequency detection function, always set 4 (output frequency frequency detection level set in n53) or 5 (output frequency frequency detection level set in n53) in n09 or n10 (multi-function output selection).

Unit no. Setting range 0 to 15 Factory setting 0

This constant is used to set a Unit no. for the Inverter.

Note that the Unit no. does not overlap with that of another slave unit.

After setting the Unit no. in n67, turn the power off (make sure that all LEDs go off), then turn the power on. This makes the setting valid.

Error History This constant can only be displayed. It cannot be set.

Information about the last error is recorded in this constant.

Recorded are Inverter errors and other errors that actuate a protective mechanism. Warning (automatically recovered error) is not recorded.

5-1 Protective and Diagnostic Functions

The 3G3EV has excellent protective and diagnostic functions. The RUN, ALARM, and transmission indicators on the front panel indicate the current Inverter status, and the data display section also displays information about an error that has occurred. These functions therefore enable the user to take the appropriate actions to correct most errors.

5-2 Troubleshooting

If the Inverter or motor does not operate properly when the system is started, constant settings or wiring may be incorrect. In this case, take the appropriate action as described below. (If an error code is displayed, refer to 5-1 Protective and Diagnostic Functions.)

5-2-1 Constants Fail to Set

is Displayed in the Data Display Section. If an attempt is made to set a value outside the allowable range, is displayed in the data display section. The value is canceled and the data display section redisplays the original value. For example, this error occurs when:

An attempt is made to set a reference frequency value higher than the maximum frequency value.

An attempt is made to set a maximum voltage frequency (basic frequency) value higher than the maximum frequency value.

Check the setting range, then set the constant correctly.

The Display Does Not Change when the Increment or Decrement Key is Pressed.

Value 0 is set in n01 (constant write-inhibit selection)

Set 1 in n01.

The Digital Operator is not connected properly.

Turn the power off. After all indicators on the front panel go off, remove the Digital Operator, then reinstall it.

5-2-2 Master Unit Displays a Message Indicating that CPU is on Hold

If the END RS indicator on the Master Unit is lit, no end unit or more than one terminator has been set. Set only the last Slave Unit (device) as a terminator. After the terminator is set correctly, turn the power off, then on.

Wiring is incorrect or broken.

Check the SYSMAC BUS two-conductor cables for incorrect wiring or for breakage. After wiring is corrected, turn the power off, then on.

Chapter 5

(

Unit Numbers are Duplicated

Check if the unit number overlaps with that of another remote I/O slave unit. After cor- recting the unit number, turn the power off, then on.

5-2-3 Master Unit Displays a Remote I/O Error The two-conductor cable broke during operation. Turn the power off, replace the cable, then turn the power on.

5-2-4 Master Unit Displays a Remote I/O Collation Error I/O allocation has not been performed. Perform I/O allocation on the SYSMAC side.

5-2-5 Motor Fails to Operate

The Motor Does Not Operate when the RUN Key on the Digital Operator is Pressed.

Operation mode was not selected correctly.

Perform one of the following steps to enable the RUN Key on the Digital Operator.

Set 0 in n02.

If 1 is set in n02, set the local/remote changeover signal to ON. The local/remote changeover signal can be switched using n08 (multi-function input selection 3).

The reference frequency is too low.

When the reference frequency is less than 1.5 Hz, the Inverter cannot operate. Change the reference frequency to 1.5 Hz or more.

The Motor Does not Operate when a Run Command is Input. Operation mode is selected incorrectly.

If 0 is set in n02, the motor does not operate even when a run command is input.

Set 1 in n02. If the local/remote changeover signal is set using n08 (multi-function input selection 3), set the signal to OFF.

The reference frequency is too low.

When the reference frequency is less than 1.5 Hz, the Inverter does not operate. Change the reference frequency to 1.5 Hz or more.

The Motor Stops during Acceleration or when a Load is Connected.

Load is too high.

The 3G3EV has a stall prevention function and full automatic torque boost function. However, if acceleration or load is too high, the motor response limit will be exceeded.

Chapter 5

)

To prevent this, increase acceleration time or reduce load. Motor capacity should be also increased.

5-2-6 Motor Rotates in the Wrong Direction The motor output line is connected incorrectly.

If terminals U, V, and W on the Inverter are correctly connected to terminals U, V, and W on the motor, the motor rotates in the forward direction when a forward rotation com- mand is input. Since the forward direction of rotation depends on the motor manufac- turer and model, check the motor specifications.

To reverse the direction of rotation, switch the wires of two phases of U, V, and W as shown below.

Inverter Motor

Forward rotation

Reverse rotation

5-2-7 Motor Deceleration is Too Slow

Deceleration Time is Too Long Even if a Braking Resistor is Connected.

Value 0 (stall prevention during deceleration) is set in n33.

When a braking resistor is connected, always set 1 (no stall prevention during decel- eration) in n33. If 0 is set, the braking resistor will not be used.

The deceleration time set in n21 (deceleration time 1) or n23 (deceleration time 2) is too long.

Check the deceleration time setting.

Motor torque is insufficient.

If the constant settings are normal and overvoltage does not occur, motor capacity is insufficient.

Motor capacity should be increased.

Chapter 5

5-2-8 Vertical-axis Load Drops when Brakes are Applied

Sequence is incorrect.

The Inverter remains in DC braking status (50% of the n31 setting) for 0.5 second after deceleration is complete. Modify the sequence so that brakes are applied when the Inverter enters DC braking status.

Brakes are inappropriate.

Always use control brakes, not holding brakes.

5-2-9 Motor Burns The dielectric strength of the motor is insufficient.

Surge arises when the motor (inductive load) is connected to the output side of the Inverter. Normally, the maximum surge voltage is approximately three times the power voltage. Therefore, the dielectric strength of the motor to be used must be higher than the maximum surge voltage.

5-2-10 Controller Receives Noise when Inverter is Started

Noise derives from Inverter switching.

Take the following actions to prevent noise:

Reduce the carrier frequency of the Inverter.

The number of internal switching times is reduced, so noise can be reduced to some extent.

Improve the frame ground.

A current generated by internal switching normally leaks into the frame ground. Therefore, connect the ground terminal with a sufficiently thick and short wire of 100

or less.

Install an input noise filter.

Install an input noise filter (3G3IV-PHF) on the power input side of the Inverter.

Install an output noise filter.

Install an output noise filter (3G3IV-PLF) on the output side of the Inverter.

Provide a separate power supply for the sensor.

If the sensor malfunctions, provide a dedicated power supply for the sensor and install a noise filter on the power supply. For the signal line, use a shielded cable.

Chapter 5

5-2-11 AM Radio Receives Noise when Inverter is Started

Noise derives from Inverter switching.

Take the following actions to prevent noise:

Reduce the carrier frequency of the Inverter.

The number of internal switching times is reduced, so noise can be reduced to some extent.

Install an input noise filter.

Install an input noise filter (3G3IV-PHF) on the power input side of the Inverter.

Install an output noise filter.

Install an output noise filter (3G3IV-PLF) on the output side of the Inverter.

Use metal box and piping.

Metal can block off radio waves. Therefore, enclose the Inverter with a metal (steel) box to prevent radio waves from being emitted from the Inverter.

5-2-12 Ground Fault Interrupter is Actuated when Inverter is Started

Leakage current flows through the Inverter.

Because switching is performed inside the Inverter, a leakage current flows through the Inverter. This leakage current may actuate the ground fault interrupter, shutting the power off.

Use a ground fault interrupter with a high leakage-current detection value (sensitivity amperage of 200 mA or more, operating time of 0.1 second or more) or the one with high-frequency countermeasures (for Inverter).

Reducing the carrier frequency value is also relatively effective.

Note also that a leakage current increases in proportion to the cable length. Normally, an approximately 5 mA leakage current is generated per meter (cable length).

5-2-13 Mechanical System Makes Noise The carrier frequency and the natural frequency of the mechanical system resonates.

Take the following actions:

Adjust the carrier frequency.

Adjusting the carrier frequency (n37) may prevent resonance from occurring.

Install vibration-proof rubber.

Install vibration-proof rubber on the motor base.

Chapter 5

5-3 Maintenance and Inspection

Daily Inspection While the system is operating, check the following items:

Check the motor for noise.

Check for abnormal heating.

Check if the ambient temperature is too high.

Check if the output current monitor display indicates a higher value than usual.

Regular Maintenance Check the items below during regular maintenance.

Before starting inspection, always turn the power off, then wait at least one minute after all indicators on the front panel go off. Touching terminals immediately after turning the power off may cause an electrical shock.

Check the terminal block screws for looseness.

Check if electrically conductive dust or oil mist adheres to the terminal block.

Check the Inverter set screws for looseness.

Check if dust or dirt builds up on the heat sink (aluminum portion on the rear of the Unit).

Check if dust builds up in the air vents.

Check if the appearance is normal.

Check if the cooling fan for the control panel operates normally. (Check for noise or abnormal vibration, and also check if the total hours of operation has exceeded the value shown in the specifications.)

Regular Parts Maintenance An Inverter consists of many different parts. It can provide its full performance only when these parts operate normally. Some electronic parts require maintenance depending on the service conditions. To allow the Inverter to operate normally over an extended peri- od of time, always perform regular inspection and parts replacement according to the service life of each part.

Regular inspection intervals vary according to the Inverter installation environment and service conditions.

The maintenance interval for this Inverter is shown below. Use this information as a guide to regular maintenance.

Chapter 5

The standard interval for regular maintenance is as follows:

Electrolytic capacitor: Approximately 5 years (8 hours of operation per day)

As for service conditions, it is assumed that the ambient temperature of the Inverter is 40C, and the Inverter is used under rated operating conditions (rated torque) and is installed as specified in the Users Manual.

To extend maintenance intervals, ambient temperatures should be lowered, and power- on time should be minimized.

Note For the maintenance method, contact your nearest local sales representative.

7-1 Notes on Using Inverter for Motor

Using Inverter for Existing Standard Motor When a standard motor is operated with this Inverter, a power loss is slightly higher than when operated with a commercial power supply.

In addition, cooling effects also decline in the low-speed range, resulting in an increase in the motor temperature. Therefore, motor torque should be reduced in the low speed range.

The figure on the right-hand side shows allowable load characteristics of a standard motor.

If 100% torque is continuously required in the low-speed range, use a special motor for use with Inverters.

Allowable Load Characteristics of Standard Motor

25% ED (or 15 minutes) 40% ED (or 20 minutes)

60% ED (or 40 minutes)

Continuous

Frequency (Hz)

To rq

ue (%

)

High-speed Operation When using the motor at a high speed (60 Hz or more), note that problems may arise in dynamic balance, bearing durability, and so on.

Torque Characteristics When the motor is operated with the Inverter, torque characteristics differ from when operated with a commercial power supply. Check the load torque characteristics of the machine to be used with the motor.

Chapter 7

«

Vibration The 3G3EV series employs high carrier PWM control to reduce motor vibration. When the motor is operated with this Inverter, motor vibration is almost the same as when op- erated with a commercial power supply.

However, motor vibration may become greater in the following cases:

Resonance with the natural frequency of mechanical system

Take special care when a machine that has been operated at a constant speed is to be operated in variable speed mode. If resonance occurs, install vibration-proof rub- ber on the motor base.

Imbalanced rotor

Take special care when the motor is operated at a high speed (60 Hz or more).

Noise Noise is almost the same as when the motor is operated with a commercial power sup- ply. However, motor noise becomes louder when the motor is operated at a speed high- er than the rated speed (60 Hz).

Using Inverter for Special Motors

Pole-changing Motor The rated amperage of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum amperage of the motor to be used. Before changing the number of poles, always make sure that the mo- tor has stopped. Otherwise, the overvoltage protection or overcurrent protection mech- anism will be actuated, resulting in an error.

Submersible Motor The rated amperage of submersible motors is higher than that of standard motors. Therefore, always select an Inverter by checking its rated amperage. When the dis- tance between the motor and the Inverter is long, use a cable thick enough to prevent motor torque reduction.

Explosion-proof Motor When an explosion-proof motor or increased safety type motor is to be used, it must be subject to an explosion-proof test in conjunction with the Inverter. This is also applicable when an existing explosion-proof motor is to be operated with the Inverter. However, since the Inverter itself is not explosion-proof, always install it in a safe place.

Chapter 7

«

Gearmotor The speed range for continuous operation differs according to the lubrication method and motor manufacturer. In particular, continuous operation of an oil-lubricated motor in the low speed range may result in burning. If the motor is to be operated at a speed high- er than 60 Hz, consult with the manufacturer.

Synchronous Motor This motor is not suitable for Inverter control. If a group of synchronous motors is individ- ually turned on and off, synchronism may be lost.

Single-phase Motor This motor is not suitable for Inverter control. It should be replaced with a three-phase motor.

Power Transmission Mechanism (Speed Reducers, Belts, Chains, and so on)

If an oil-lubricated gearbox or speed reducer is used in the power transmission mecha- nism, note that oil lubrication will be affected when the motor operates only in the low speed range. Note also that the power transmission mechanism will make noise and experience problems with service life and durability if the motor is operated at a speed higher than 60 Hz.

Checking Accessories Note that this manual is the only accessory provided with the 3G3EV (SYSMAC BUS Model). Set screws and other necessary parts must be prepared by customers.

1-2 Precautions

To ensure safe operation of the 3G3EV, note the following items:

Always Hold the Heat Sink During Removal. When moving the 3G3EV, always hold the heat sink (aluminum portion on the rear of the Unit).

Heat sink

Watch Out for Residual Voltage On Charged Portions After the power is turned off, residual voltage remains in the capacitor inside the Inverter. Therefore, touching terminals immediately after turning the power off may cause an electrical shock.

If an inspection or some other task is to be performed, always wait at least one minute from the time all indicators on the front panel go off.

(Note that this warning is applicable whenever you perform any task after turning the main circuit off.)

Do Not Remove the Digital Operator When the Main Circuit is Still On.

Always turn the main circuit off before removing the digital operator.

Removing the digital operator with the main circuit ON may cause an electrical shock and damage the equipment.

Chapter 1

Do Not Modify Wiring or Check Signals When the Main Circuit is On.

Always turn the main circuit off before modifying wiring or checking signals.

Touching terminals while the main circuit is on may cause an electrical shock and dam- age the equipment.

Do Not Conduct a Dielectric Strength Test. Because the 3G3EV Inverter is an electronic control unit using semiconductor, never conduct a dielectric strength test or an insulation resistance test for the control circuit.

Modify Constant Settings Correctly. Always modify the constant settings according to the procedures described in this manual.

Chapter 1

2-1 Features

Easy to Use

Basic Constants Displayed On Indicators Constants for basic operations such as frequency setting and acceleration/deceleration time setting are displayed on dedicated indicators. Therefore, constant numbers can be confirmed easily.

Easy to Install

Very Small and Lightweight The 3G3EV Inverter is approximately half the size of our Low-noise General-purpose Inverters in terms of volume and weight percentage. This improves space efficiency and operating efficiency (including easier removal).

Optional DIN Track An optional DIN track is available. This DIN track enables the user to mount the 3G3EV Inverter on the DIN track with a one-touch operation.

Chapter 2

Easy to Wire

Using Two-conductor Cables to Minimize Wiring Two-conductor cables (VCTF) enable the Inverter to be connected a higher-level PC.

Easy Wiring without Having to Open the Front Cover This Inverter can be wired just by opening the terminal block cover.

Separate Input and Output Terminal Blocks Power input terminals are located in the upper section, while motor output terminals are in the lower section. In this way, the input and output terminal blocks are separated ac- cording to the contactors, so incorrect wiring can be prevented.

Soldering No Longer Necessary No connector means no soldering.

Easy to Operate

Bitwise Communication Making Programming Easier No special communication program is required. Allocated input and output areas can be used to control the Inverter in a way similar to ordinary I/O Units.

Switching the Operation Mode by Simple Key Operation For example, after a test run is performed using the Digital Operator, it can be easily switched to a production run in communication mode by simple key operation.

Checking a Test Run with Various Monitors Output frequency, output current, and the direction of motor rotation appear in the dis- play section of the Digital Operator, so the mechanical system can be easily monitored during a test run.

Low Noise An insulated gate bipolar transistor (IGBT) power element has been adopted to elimi- nate metallic noise.

High-torque Operation Even in Low Speed Range A torque rate of 150% can be achieved even in a low speed range where output frequen- cy is only 3 Hz. Thus, acceleration time can be reduced.

Ambient Temperature Control To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature rises.

If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50C.

The surface temperature of the Inverter may reach 30C higher than the ambient tem- perature. Therefore, keep all thermally susceptible devices and wires away from the Inverter.

Protecting the Inverter from Foreign Matter during Installation Place a cover over the Inverter to shield it from metal powder produced by drilling dur- ing installation.

(Upon completion of installation, always remove the cover from the Inverter. Other- wise, ventilation will be affected, causing the invert to overheat.)

Note 1. If a 3G3EV-ABR is used in single-phase input mode, 200 to 240 VAC power with a frequency of 50/60 Hz must be input between terminals R and S.

Note 2. Use cabtire cables (VCTF 0.75 x 2C) to connect to the Remote I/O Master Unit.

3-2-2 Wiring Around the Main Circuit

System reliability and noise resistance are affected by the wiring method used. Therefore, always follow the instructions given below when connect- ing the Inverter to peripheral devices and other parts.

Wire Size and Molded-Case Circuit Breaker to be Used For the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables.

If the cable is long and may cause voltage drops, increase the wire size according to the cable length.

U V W

Determining the Wire Size Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage.

Line voltage drop VD is calculated as follows:

VD (V) = 3 x wire resistance (/km) x wire length (m) x amperage (A) x 10—3

Wiring on the Input Side of Main Circuit

Installing a Molded-case Circuit Breaker Always connect the power input terminals (R, S, and T) and power supply via a molded- case circuit breaker.

Installing a Ground Fault Interrupter If a ground fault interrupter is to be connected to the wire on the primary side (R, S, and T) of the main circuit, use either of the following interrupters to prevent malfunctions:

Ground fault interrupter with a sensitivity amperage of 200 mA or more and with an operating time of 0.1 second or more

Ground fault interrupter with high-frequency countermeasures (for Inverter)

Chapter 3

Installing a Magnetic Contactor This Inverter can be used without a magnetic contactor (MC) on the power supply side.

If the power supply for the main circuit is to be shut off because of the sequence, a mag- netic contactor can be used instead of a molded-case circuit breaker.

However, when a magnetic contactor is installed on the primary side of the main circuit to forcibly stop a load, note that regenerative braking does not work and the load coasts to a stop.

A load can be started and stopped by opening and closing the magnetic contactor on the primary side. Note, however, that frequently opening and closing the magnetic contactor may cause the Inverter to break down.

When the Inverter is operated with a Digital Operator, automatic operation cannot be performed after recovery from a power interruption.

If a braking resistor unit is to be used, program the sequence so that the magnetic con- tactor is turned off by the contact of the units thermal relay.

Connecting Input Power Supply to the Terminal Block Because the phase sequence of input power supply is irrelevant to the phase sequence (R, S, T) of the terminal block, input power supply can be connected to any terminal on the terminal block.

Installing an AC Reactor If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advance capacitor is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down. To prevent this, install an optional AC reactor on the input side of the Inverter. This also improves the power factor on the power supply side.

Installing a Surge Absorber Always use a surge absorber or diode for the inductive loads to be connected to the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

Chapter 3

Installing a Noise Filter on the Power Supply Side Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

Wiring on the Output Side of Main Circuit

Connecting the Terminal Block to the Load Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.

Chapter 3

Never Connect Power Supply to Output Terminals

Caution Never connect a power supply to output terminals U, V, and W. If voltage is applied to the output terminals, the internal mechanism of the Inverter will be damaged.

Never Short or Ground the Output Terminals

Caution If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Also, be careful not to short the output wires.

Do Not Use a Phase Advance Capacitor or Noise Filter Never connect a phase advance capacitor or LC/RC noise filter to the output circuit. Do- ing so may result in damage to the Inverter or cause other parts to burn.

Do Not Use an Electromagnetic Switch Do not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is connected to the Inverter during operation, an inrush current will actuate the overcurrent protective circuit in the Inverter.

Installing a Thermal Relay This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi- polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set to 0.0 (no thermal protection) for constant No. 31 (THR indicator).

In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is turned off by the contact of the thermal relay.

Installing a Noise Filter on the Output Side Connect a noise filter to the output side of the Inverter to reduce radio noise and induc- tion noise.

Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller to malfunction.

Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio receiver to make noise.

How to Prevent Induction Noise As described above, a noise filter can be used to prevent induction noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction noise.

How to Prevent Radio Noise Radio noise is generated from the Inverter as well as the input and output lines. To re- duce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.

The cable between the Inverter and the motor should be as short as possible.

Chapter 3

Cable Length between Inverter and Motor If the cable between the Inverter and the motor is long, the high-frequency leakage cur- rent will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in n37) as shown in the table below.

Cable length between Inverter and motor 50 m max. 100 m max. Carrier frequency (n37) 10 kHz max. (1, 2, 3, 4) 5 kHz max. (1, 2)

Ground Wiring Always use a ground terminal with a ground resistance of 100 or less.

Do not share the ground wire with other devices such as a welder or power tool.

Always use a ground wire that complies with technical standards on electrical equip- ment. Route the ground wire so that the total length is as short as possible.

When using more than one Inverter, be careful not to loop the ground wire.

5 m max.

1.25 mm2 min.

Chapter 3

Note Minimize the total length (5 m or less) between the ground electrode and the ground terminal, and also use a thick wire (1.25 m2 or more). Leakage current flows through the Inverter. Therefore, if the distance between the ground elec- trode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.

3-2-3 Wiring Control Circuit Terminals

The control signal line must be 50 m or less and must be separated from the power line.

Wiring Sequence Input/Output Terminals Wire the multi-function input1 terminals (S1 and SC) and the multi-function output 1 ter- minals (PA and PC) as described below.

Always separate the transmission cables from the main circuit cables and other power cables.

Always connect the positive terminal to the positive terminal and the negative terminal to the negative terminal.

Wire the Remote I/O Master Unit (RM201) on the SYSMAC side first, then continue wiring in order. Set the last Slave Unit (device) as a terminator.

The overall cable length must be 200 m or less.

Always separate the transmission line from the main circuit cables and other power cables. In particular, the transmission line must not be parallel to or close to the output cables from the Inverter.

Chapter 3

)

3-2-5 Setting the Terminator

The Remote I/O Unit at the end of the system must be set as the terminator. Otherwise, all Remote I/O Units cannot operate. This section describes how to set the 3G3EV-AR as a terminator.

Setting the Terminator Open the terminal block cover in the lower part of the Inverter. The terminator setting switch is located on the left side of the control circuit terminals.

Sliding the switch to the right sets the Inverter as the terminator.

Terminator setting switch

Notes on Setting the Terminator The last Slave Unit under each Remote I/O Master Unit must be set as the terminator.

Always set a terminator even when only one unit is to be connected.

If no terminator is set, the Remote I/O System fails to operate, and the PC also fails to start operation even when the Master Unit enters run mode. In this case, the END RS indicator (terminator checking) remains lit. The Programming Console also displays a message indicating that CPU is on hold.

Chapter 3

4-1 Preparation Procedure

These constants are used to set acceleration time (required to increase the output fre- quency from the stopped state to the maximum frequency) and deceleration time (re- quired to decrease the output frequency from the maximum frequency to the stopped state). (Set the maximum frequency in n24.)

The unit of setting is as follows: 0.0 to 99.9 (seconds): 0.1 (second) 100 to 999 (seconds): 1 (second)

Acceleration and deceleration times can be changed even during operation. If, for ex- ample, acceleration time is to changed, light the ACC indicator with the Mode Key first, press the Increment or Decrement Key to change the value, then press the Enter Key. Deceleration time can be also changed in the same way. (Light the DEC indicator be- fore changing the deceleration time.)

These three constants are used to set a V/f pattern.

Check the motor specifications and set each constant as follows: n24: Maximum frequency or rated frequency n25: Rated voltage n26: Rated frequency

The value set in n24 (maximum frequency) must be equal to or greater than the value set in n26 (maximum voltage frequency). Otherwise, an error will result.

(see note 1) (A) Factory setting See note 2

Unit of setting 0.1 (A)

This constant is used to set an electronic thermal reference value to protect the motor from overheating. Set the rated motor amperage in this constant.

If 0.0 is set in this constant, no thermal protection is assumed, so motor overload will not be detected.

The setting range and factory setting for this constant are as follows:

Stall Prevention during Deceleration Setting range 0, 1 Factory setting 0

This constant is used to select the action to prevent overvoltage during deceleration.

Value Description 0 Stall prevention during deceleration 1 No stall prevention during deceleration

Note 1. If a braking resistor is to be connected, always set 1 (no stall prevention during deceleration) in this constant.

Operation after Recovery from Power Interruption Setting range 0, 1, 2 Factory setting 0

This constant is used to select the processing to be performed after recovery from an instantaneous power interruption.

Value Description 0 Discontinues operation. 1 Continues operation only if power interruption is within 0.5 second. 2 Continues operation unconditionally (with no error output).

Note If 1 or 2 is selected to continue operation, the Inverter automatically searches the motor speed (even when the motor is in a free-running state) and continues smooth operation. This function is called the speed search function.

Carrier Frequency Setting range 1, 2, 3, 4 Factory setting 4 (10 kHz)

This constant is used to set a pulse-width-modulated (PWM) carrier frequency.

Value Carrier frequency 1 2.5 (kHz) 2 5 (kHz) 3 7.5 (kHz) 4 10 (kHz)

Chapter 4

Note As the cable between the Inverter and the motor becomes longer, a high-frequen- cy leakage current from the cable increases, causing the Inverter output current to increase as well. This may also affect peripheral devices. To prevent this, ad- just the carrier frequency according to the following standards:

Cable length of 50 meters or less: 10 kHz or less

Cable length of 50 to 100 meters: 5 kHz or less

Over-torque Detection Function Selection Setting range 0 to 4 Factory setting 0

Over-torque Detection Level Setting range 30 to 200 (%) Factory setting 160 (%) Unit of setting 1 (%)

Over-torque Detection Time Setting range 0.1 to 10

(seconds) Factory setting 0.1 (seconds)

Unit of setting 0.1 (seconds)

When excessive load is applied to the equipment, the Inverter detects any increase in output current and displays the fault according to the n09 and n10 settings (multi-func- tion output selection).

n50 is used to specify whether over-torque is to be monitored and specify the action to be taken when over-torque is detected.

n50 setting Description 0 Inverter does not monitor over-torque. 1 Inverter monitors over-torque only when speed is matched. It continues

operation (issues warning) even after over-torque is detected. 2 Inverter monitors over-torque only when speed is matched. It discontinues

operation (through protection function) when over-torque is detected. 3 Inverter always monitors over-torque during operation. It continues

operation (issues warning) even after over-torque is detected. 4 Inverter always monitors over-torque during operation. It discontinues

operation (through protection function) when over-torque is detected.

n51 is used to set the over-torque detection level. Specify this value in terms of the percentage of the rated output current.

n52 is used to set the over-torque detection time (in seconds).

Chapter 4

Frequency Detection Level Setting range 0.4 to 400 (Hz) Factory setting 0.0 (Hz) Unit of setting 0.0 to 99.9 (Hz) : 0.1(Hz)

100 to 400 (Hz) : 1 (Hz)

When the output frequency drops below or exceeds the value set in n53, the Inverter displays the fault according to the n09 and n10 settings (multi-function output selec- tion).

To use the frequency detection function, always set 4 (output frequency frequency detection level set in n53) or 5 (output frequency frequency detection level set in n53) in n09 or n10 (multi-function output selection).

Unit no. Setting range 0 to 15 Factory setting 0

This constant is used to set a Unit no. for the Inverter.

Note that the Unit no. does not overlap with that of another slave unit.

After setting the Unit no. in n67, turn the power off (make sure that all LEDs go off), then turn the power on. This makes the setting valid.

Error History This constant can only be displayed. It cannot be set.

Information about the last error is recorded in this constant.

Recorded are Inverter errors and other errors that actuate a protective mechanism. Warning (automatically recovered error) is not recorded.

5-1 Protective and Diagnostic Functions

The 3G3EV has excellent protective and diagnostic functions. The RUN, ALARM, and transmission indicators on the front panel indicate the current Inverter status, and the data display section also displays information about an error that has occurred. These functions therefore enable the user to take the appropriate actions to correct most errors.

Data Display and Action to be Taken when Warning Status Arises

The ALARM indicator flashes when warning status arises. The data display section also flashes.

When warning status arises, no error code is output.

Eliminating the cause recovers the system automatically.

Data display

Description Action

flashing Main circuit undervoltage (UV) The DC voltage of the main circuit dropped below the low-voltage detection level when the Inverter was stopped.

Check the power voltage.

Check the power input line for discon- nection.

Check the terminal block screws for looseness.

flashing Main circuit overvoltage (OV) The DC voltage of the main circuit exceeded the overvoltage detection level when the Inverter was stopped.

Check the power voltage.

flashing Radiation fin overheated (OH) The radiation fin overheated when the Inverter was stopped.

Check the ambient temperature.

Install a cooling fan or air conditioner.

flashing Digital Operator stopped (STP) The STOP/RESET Key on the Digital Operator was pressed while the Inverter was being operated via communication. The Inverter stops the motor according to the n03 setting.

Set the run command (bit 0 of channel n +1) to OFF (0).

flashing Over-torque (OL3) A current exceeding the value set in n51 flowed for more than the time set in n52.

Check if the n51 and n52 settings are appropriate.

Check the machine use status, and eliminate the cause of the problem.

flashing Sequence error (SEr) A local/remote changeover command was input during operation.

Check the sequence (PC program).

Data Display and Action to be Taken when Protective Mechanism is Actuated

The ALARM indicator lights up when the protective mechanism is actuated. In this event, Inverter output is shut off, and the motor coasts to a stop.

Check the cause of the error, take the necessary action, and perform fault reset or turn the power off, then on.

Chapter 5

Data display

Description Cause and action

Overcurrent (OC) The Inverter output current instantaneously exceeded 250% of the rated amperage.

5-2 Troubleshooting

If the Inverter or motor does not operate properly when the system is started, constant settings or wiring may be incorrect. In this case, take the appropriate action as described below. (If an error code is displayed, refer to 5-1 Protective and Diagnostic Functions.)

5-2-1 Constants Fail to Set

is Displayed in the Data Display Section. If an attempt is made to set a value outside the allowable range, is displayed in the data display section. The value is canceled and the data display section redisplays the original value. For example, this error occurs when:

An attempt is made to set a reference frequency value higher than the maximum frequency value.

An attempt is made to set a maximum voltage frequency (basic frequency) value higher than the maximum frequency value.

Check the setting range, then set the constant correctly.

The Display Does Not Change when the Increment or Decrement Key is Pressed.

Value 0 is set in n01 (constant write-inhibit selection)

Set 1 in n01.

The Digital Operator is not connected properly.

Turn the power off. After all indicators on the front panel go off, remove the Digital Operator, then reinstall it.

5-2-2 Master Unit Displays a Message Indicating that CPU is on Hold

If the END RS indicator on the Master Unit is lit, no end unit or more than one terminator has been set. Set only the last Slave Unit (device) as a terminator. After the terminator is set correctly, turn the power off, then on.

Wiring is incorrect or broken.

Check the SYSMAC BUS two-conductor cables for incorrect wiring or for breakage. After wiring is corrected, turn the power off, then on.

Chapter 5

(

Unit Numbers are Duplicated

Check if the unit number overlaps with that of another remote I/O slave unit. After cor- recting the unit number, turn the power off, then on.

5-2-3 Master Unit Displays a Remote I/O Error The two-conductor cable broke during operation. Turn the power off, replace the cable, then turn the power on.

5-2-4 Master Unit Displays a Remote I/O Collation Error I/O allocation has not been performed. Perform I/O allocation on the SYSMAC side.

5-2-5 Motor Fails to Operate

The Motor Does Not Operate when the RUN Key on the Digital Operator is Pressed.

Operation mode was not selected correctly.

Perform one of the following steps to enable the RUN Key on the Digital Operator.

Set 0 in n02.

If 1 is set in n02, set the local/remote changeover signal to ON. The local/remote changeover signal can be switched using n08 (multi-function input selection 3).

The reference frequency is too low.

When the reference frequency is less than 1.5 Hz, the Inverter cannot operate. Change the reference frequency to 1.5 Hz or more.

The Motor Does not Operate when a Run Command is Input. Operation mode is selected incorrectly.

If 0 is set in n02, the motor does not operate even when a run command is input.

Set 1 in n02. If the local/remote changeover signal is set using n08 (multi-function input selection 3), set the signal to OFF.

The reference frequency is too low.

When the reference frequency is less than 1.5 Hz, the Inverter does not operate. Change the reference frequency to 1.5 Hz or more.

The Motor Stops during Acceleration or when a Load is Connected.

Load is too high.

The 3G3EV has a stall prevention function and full automatic torque boost function. However, if acceleration or load is too high, the motor response limit will be exceeded.

Chapter 5

)

To prevent this, increase acceleration time or reduce load. Motor capacity should be also increased.

5-2-6 Motor Rotates in the Wrong Direction The motor output line is connected incorrectly.

If terminals U, V, and W on the Inverter are correctly connected to terminals U, V, and W on the motor, the motor rotates in the forward direction when a forward rotation com- mand is input. Since the forward direction of rotation depends on the motor manufac- turer and model, check the motor specifications.

To reverse the direction of rotation, switch the wires of two phases of U, V, and W as shown below.

Inverter Motor

Forward rotation

Reverse rotation

5-2-7 Motor Deceleration is Too Slow

Deceleration Time is Too Long Even if a Braking Resistor is Connected.

Value 0 (stall prevention during deceleration) is set in n33.

When a braking resistor is connected, always set 1 (no stall prevention during decel- eration) in n33. If 0 is set, the braking resistor will not be used.

The deceleration time set in n21 (deceleration time 1) or n23 (deceleration time 2) is too long.

Check the deceleration time setting.

Motor torque is insufficient.

If the constant settings are normal and overvoltage does not occur, motor capacity is insufficient.

Motor capacity should be increased.

Chapter 5

5-2-8 Vertical-axis Load Drops when Brakes are Applied

Sequence is incorrect.

The Inverter remains in DC braking status (50% of the n31 setting) for 0.5 second after deceleration is complete. Modify the sequence so that brakes are applied when the Inverter enters DC braking status.

Brakes are inappropriate.

Always use control brakes, not holding brakes.

5-2-9 Motor Burns The dielectric strength of the motor is insufficient.

Surge arises when the motor (inductive load) is connected to the output side of the Inverter. Normally, the maximum surge voltage is approximately three times the power voltage. Therefore, the dielectric strength of the motor to be used must be higher than the maximum surge voltage.

5-2-10 Controller Receives Noise when Inverter is Started

Noise derives from Inverter switching.

Take the following actions to prevent noise:

Reduce the carrier frequency of the Inverter.

The number of internal switching times is reduced, so noise can be reduced to some extent.

Improve the frame ground.

A current generated by internal switching normally leaks into the frame ground. Therefore, connect the ground terminal with a sufficiently thick and short wire of 100

or less.

Install an input noise filter.

Install an input noise filter (3G3IV-PHF) on the power input side of the Inverter.

Install an output noise filter.

Install an output noise filter (3G3IV-PLF) on the output side of the Inverter.

Provide a separate power supply for the sensor.

If the sensor malfunctions, provide a dedicated power supply for the sensor and install a noise filter on the power supply. For the signal line, use a shielded cable.

Chapter 5

5-2-11 AM Radio Receives Noise when Inverter is Started

Noise derives from Inverter switching.

Take the following actions to prevent noise:

Reduce the carrier frequency of the Inverter.

The number of internal switching times is reduced, so noise can be reduced to some extent.

Install an input noise filter.

Install an input noise filter (3G3IV-PHF) on the power input side of the Inverter.

Install an output noise filter.

Install an output noise filter (3G3IV-PLF) on the output side of the Inverter.

Use metal box and piping.

Metal can block off radio waves. Therefore, enclose the Inverter with a metal (steel) box to prevent radio waves from being emitted from the Inverter.

5-2-12 Ground Fault Interrupter is Actuated when Inverter is Started

Leakage current flows through the Inverter.

Because switching is performed inside the Inverter, a leakage current flows through the Inverter. This leakage current may actuate the ground fault interrupter, shutting the power off.

Use a ground fault interrupter with a high leakage-current detection value (sensitivity amperage of 200 mA or more, operating time of 0.1 second or more) or the one with high-frequency countermeasures (for Inverter).

Reducing the carrier frequency value is also relatively effective.

Note also that a leakage current increases in proportion to the cable length. Normally, an approximately 5 mA leakage current is generated per meter (cable length).

5-2-13 Mechanical System Makes Noise The carrier frequency and the natural frequency of the mechanical system resonates.

Take the following actions:

Adjust the carrier frequency.

Adjusting the carrier frequency (n37) may prevent resonance from occurring.

Install vibration-proof rubber.

Install vibration-proof rubber on the motor base.

Chapter 5

5-3 Maintenance and Inspection

Daily Inspection While the system is operating, check the following items:

Check the motor for noise.

Check for abnormal heating.

Check if the ambient temperature is too high.

Check if the output current monitor display indicates a higher value than usual.

Regular Maintenance Check the items below during regular maintenance.

Before starting inspection, always turn the power off, then wait at least one minute after all indicators on the front panel go off. Touching terminals immediately after turning the power off may cause an electrical shock.

Check the terminal block screws for looseness.

Check if electrically conductive dust or oil mist adheres to the terminal block.

Check the Inverter set screws for looseness.

Check if dust or dirt builds up on the heat sink (aluminum portion on the rear of the Unit).

Check if dust builds up in the air vents.

Check if the appearance is normal.

Check if the cooling fan for the control panel operates normally. (Check for noise or abnormal vibration, and also check if the total hours of operation has exceeded the value shown in the specifications.)

Regular Parts Maintenance An Inverter consists of many different parts. It can provide its full performance only when these parts operate normally. Some electronic parts require maintenance depending on the service conditions. To allow the Inverter to operate normally over an extended peri- od of time, always perform regular inspection and parts replacement according to the service life of each part.

Regular inspection intervals vary according to the Inverter installation environment and service conditions.

The maintenance interval for this Inverter is shown below. Use this information as a guide to regular maintenance.

Chapter 5

The standard interval for regular maintenance is as follows:

Electrolytic capacitor: Approximately 5 years (8 hours of operation per day)

As for service conditions, it is assumed that the ambient temperature of the Inverter is 40C, and the Inverter is used under rated operating conditions (rated torque) and is installed as specified in the Users Manual.

To extend maintenance intervals, ambient temperatures should be lowered, and power- on time should be minimized.

Note For the maintenance method, contact your nearest local sales representative.

7-1 Notes on Using Inverter for Motor

Using Inverter for Existing Standard Motor When a standard motor is operated with this Inverter, a power loss is slightly higher than when operated with a commercial power supply.

In addition, cooling effects also decline in the low-speed range, resulting in an increase in the motor temperature. Therefore, motor torque should be reduced in the low speed range.

The figure on the right-hand side shows allowable load characteristics of a standard motor.

If 100% torque is continuously required in the low-speed range, use a special motor for use with Inverters.

Allowable Load Characteristics of Standard Motor

25% ED (or 15 minutes) 40% ED (or 20 minutes)

60% ED (or 40 minutes)

Continuous

Frequency (Hz)

To rq

ue (%

)

High-speed Operation When using the motor at a high speed (60 Hz or more), note that problems may arise in dynamic balance, bearing durability, and so on.

Torque Characteristics When the motor is operated with the Inverter, torque characteristics differ from when operated with a commercial power supply. Check the load torque characteristics of the machine to be used with the motor.

Chapter 7

«

Vibration The 3G3EV series employs high carrier PWM control to reduce motor vibration. When the motor is operated with this Inverter, motor vibration is almost the same as when op- erated with a commercial power supply.

However, motor vibration may become greater in the following cases:

Resonance with the natural frequency of mechanical system

Take special care when a machine that has been operated at a constant speed is to be operated in variable speed mode. If resonance occurs, install vibration-proof rub- ber on the motor base.

Imbalanced rotor

Take special care when the motor is operated at a high speed (60 Hz or more).

Noise Noise is almost the same as when the motor is operated with a commercial power sup- ply. However, motor noise becomes louder when the motor is operated at a speed high- er than the rated speed (60 Hz).

Using Inverter for Special Motors

Pole-changing Motor The rated amperage of pole-changing motors differs from that of standard motors. Select, therefore, an appropriate Inverter according to the maximum amperage of the motor to be used. Before changing the number of poles, always make sure that the mo- tor has stopped. Otherwise, the overvoltage protection or overcurrent protection mech- anism will be actuated, resulting in an error.

Submersible Motor The rated amperage of submersible motors is higher than that of standard motors. Therefore, always select an Inverter by checking its rated amperage. When the dis- tance between the motor and the Inverter is long, use a cable thick enough to prevent motor torque reduction.

Explosion-proof Motor When an explosion-proof motor or increased safety type motor is to be used, it must be subject to an explosion-proof test in conjunction with the Inverter. This is also applicable when an existing explosion-proof motor is to be operated with the Inverter. However, since the Inverter itself is not explosion-proof, always install it in a safe place.

Chapter 7

«

Gearmotor The speed range for continuous operation differs according to the lubrication method and motor manufacturer. In particular, continuous operation of an oil-lubricated motor in the low speed range may result in burning. If the motor is to be operated at a speed high- er than 60 Hz, consult with the manufacturer.

Synchronous Motor This motor is not suitable for Inverter control. If a group of synchronous motors is individ- ually turned on and off, synchronism may be lost.

Single-phase Motor This motor is not suitable for Inverter control. It should be replaced with a three-phase motor.

Power Transmission Mechanism (Speed Reducers, Belts, Chains, and so on)

If an oil-lubricated gearbox or speed reducer is used in the power transmission mecha- nism, note that oil lubrication will be affected when the motor operates only in the low speed range. Note also that the power transmission mechanism will make noise and experience problems with service life and durability if the motor is operated at a speed higher than 60 Hz.
