Summary of Contents for Siemens MICROMASTER Vector

Источник

Ввод в эксплуатацию с базовой панелью оператора (ВОР) Базовая панель оператора (BOP), поставляемая как опция, дает возможность доступа к параметрам преобразователя и обеспечивает специфическую пользовательскую настройку MICROMASTER 440. BOP может использоваться для конфигурирования боль- шинства преобразователей MICROMASTER 440. Поэтому нет необходимости покупать свою панель BOP для каждо- го преобразователя.
Панель имеет сегментные индикаторы для чтения и записи параметров преобразователя. Панель не имеет возможности собственного хранения информации и параметров после её снятия.

Примечание
• При установке панель не позволяет управлять двигателем (пуск/стоп), если используются установки привода по умолчанию. Для активизации возмож- ности управления необходимо установить параметры Р0700 и Р1000 в «1».

• Панель может сниматься и устанавливаться на преобразователе при вклю-

ченном питании преобразователя.

• Если панель предназначена для управления двигателем (Р0700 = 1), то привод остановится после снятия панели.

IMPORTANT

WARNING

In order to ensure correct and safe operation, it is vital the following instructions are strictly adhered to:

•

Operation of a motor with a higher nominal power than the inverter or a nominal power less than half that of the inverter is not allowed. The inverter must only be operated when the nominal current in P083 exactly matches the motor rating plate nominal current.

•

The motor data parameters must be accurately entered (P080-P085) and an autocalibration performed (P088=1) before the motor is started. Unstable/unpredictable motor operation (eg. reverse rotation) may result if this is not done. If this instability occurs, the mains supply to the converter must be disconnected.

When using the analogue input, the DIP switches must be correctly set and the analogue input type selected (P023) before enabling the analogue input with P006. If this is not done, the motor may start inadvertently.

1.2 Wiring Guidelines to Minimise the Effects of EMI

1. OVERVIEW

The inverters are designed to operate in an industrial environment where a high level of Electro-Magnetic

Interference (EMI) can be expected. Usually, good installation practices will ensure safe and trouble-free operation. If problems are encountered, the following guidelines may prove useful. In particular, grounding of the system at the inverter, as described below, may prove effective. Figures 1.2.1-1.2.3 illustrate how an RFI suppression filter should be installed and connected to the MICROMASTER Vector.

(1) Ensure that all equipment in the cubicle is well earthed using short, thick earthing cable connected to a common star point or busbar. It is particularly important that any control equipment that is connected to the inverter (such as a PLC) is connected to the same earth or star point as the inverter via a short, thick link. Flat conductors (e.g. braids or metal brackets) are preferred as they have lower impedance at high frequencies.

The return earth from motors controlled by the inverter should be connected directly to the earth connection (PE) on the associated inverter.

(2)

(3)

(4)

(5)

(6)

(7)

(8)

On the MIDIMASTER Vector, use saw-tooth washers when mounting the inverter and ensure that a good electrical connection is made between the heatsink and the panel, removing paint if necessary.

Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of the cable neatly, ensuring that unscreened wires are as short as possible. Use cable glands whenever possible.

Separate the control cables from the power connections as much as possible, using separate trunking, etc. If control and power cables cross, arrange the cables so that they cross at 90° if possible.

Ensure that contactors in the cubicle are suppressed, either with R-C suppressors for AC contactors or ‘flywheel’ diodes for DC contactors, fitted to the coils. Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the relay on the inverter.

Use screened or armoured cables for the motor connections and ground the screen at both ends via the cable glands.

If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI filter should be used to reduce the conducted and radiated interference from the inverter. For optimum performance, there should be a good conductive bond between filter and metal mounting plate.

For Frame Size A units (Fig.1.2.1), the flat earth braid strap, supplied with the unit, should be fitted to minimise emissions.

1.3 Electrical Installation — General Notes

1.3.1 Operation with Unearthed (IT) Supplies

The MICROMASTER Vector will operate from unearthed supplies and will continue to operate if an input phase is shorted to earth. If an output phase is shorted to earth, the MICROMASTER Vector will trip and indicate F002.

Note: MIDIMASTER Vector inverters will operate from unearthed supplies provided that the switching frequency is set to 2kHz (P076 = 6 or 7).

1.3.2 Operation with Residual Current Device (RCD)

The MICROMASTER and MIDIMASTER Vector inverters will operate without nuisance tripping with an RCD

(also called ELCBs or RCCBs) fitted to the input providing:

•

A type B RCD is used.

•

The trip limit of the RCD is 300mA.

•

The neutral of the supply is earthed.

•

Only one inverter is supplied from each RCD.

•

The output cables are less than 50m (screened ) or 100m (unscreened).

1.3.3 Installation after a Period of Storage

It is necessary to reform the capacitors in the inverter if the unit has been stored for a prolonged period:

•

Period of storage 1 year old or less:

No reforming is required.

•

1 — 2 years old:

Apply power to the inverter one hour before giving the run command (preparation time 1 hour).

•

2 — 3 years old:

G85139-H1751-U529-D1

4/8/99 10

1. OVERVIEW English

Use a variable AC supply. Apply 25% of input voltage for 30 minutes. Increase volts to 50% for a further

30 minutes. Increase volts to 75% for further 30 minutes. Increase volts to 100% for a further 30 minutes.

Now ready for run signal (preparation time 2 hours).

•

3 years and over:

As with 2 — 3 years, but the steps should be 2 hours (preparation time 8 hours).

1.3.4 Operation with Long Cables

Motor cable lengths vary depending on type of cable, power rating and voltage rating — and in some cases can be as long as 200m without the need for additional chokes. Refer to DA64 catalogue for further details.

In any case, all inverters will operate at full specification with cable lengths up to 25m for screened cable or

50m for unscreened cables.

2.2 Electrical Installation

Read the Wiring Guidelines given in section 1.2 before commencing installation.

The electrical connectors on the MICROMASTER Vector are shown in Figure 2.2.1.

Asynchronous and synchronous motors can be connected to the

MICROMASTER Vector inverters either individually or in parallel.

Note:If a synchronous motor is connected to the inverter, the motor current may be two and a half to three times greater than that expected, so, the inverter must be de-rated accordingly. Also, the inverter cannot be used in vector mode when connected to a synchronous motor (P077= 0 or 2).

3. INSTALLATION – MIDIMASTER Vector English

To gain access to the power and control terminals:

•

Frame size 4, 5 : remove the four M4 screws from the front cover and remove the cover from the inverter.

•

Frame size 6: remove the six M4 screws from the front cover and remove the cover from the inverter.

•

Frame size 7: remove the four M4 screws from the lower front cover and remove the lower front cover from the inverter.

WARNING

Ensure that the motor is configured for the correct supply voltage.

Make sure that the input power supply is isolated before making or changing any connections.

CAUTION

The control, power supply and motor leads must be laid separately. They must not be fed through the same cable conduit/trunking.

High voltage insulation test equipment must not be used on cables connected to the inverter.

Use screened cable for the control cable, Class 1 60/75 o

C copper wire only.

Feed the cables through the correct glands in the base of the inverter. Secure the cable glands to the inverter and connect the leads to the power, motor and control terminals in accordance with the information supplied in sections 3.2.1 and 3.2.2. Ensure that the leads are connected correctly and the equipment is properly earthed.

Frame size 4 and 5: Tighten up each of the power and motor terminal screws to 1.1 Nm.

Frame size 6: Tighten up each of the power and motor terminal Allen-screws to 3.0 Nm.

Frame size 7: Tighten up each of the M12 power and motor terminal nuts to 30 Nm.

Secure the front cover to the inverter when all connections are complete.

3.2.1 Power and Motor Connections

1. Ensure that the power source supplies the correct voltage and the necessary current. Ensure that the appropriate circuit-breaker or fuses with the specified current rating are connected between the power supply and inverter (see section .

2. Connect the power input to the power terminals L1, L2, L3 (3 phase) and earth (PE) (shown in Figure 3.2.1) using a 4-core cable and lugs to suit the cable size. For the cross-section of each core, see section 8.

3. Use a 4-core screened cable and suitable lugs to connect the motor leads to the motor terminals U, V, W and earth (PE) (shown in Figure 3.2.1).

Note: For operation with cables longer than 25m see section 1.3.4

4. If required, connect the braking unit leads to the DC- and DC+ terminals.

5. Tighten all the power and motor terminals.

Asynchronous and synchronous motors can be connected to the MIDIMASTER Vector inverters either individually or in parallel.

Note : If a synchronous motor is connected to the inverter, the motor current may be two and a half to three times greater than that expected so the inverter must be de-rated accordingly.

4.2 Basic Operation

Refer to section 6 for a full description of each parameter.

4.2.1 General

(1) The inverter does not have a main power switch and is therefore live when the mains supply is connected. It waits with the output disabled until the RUN button is pressed or for the presence of a digital ON signal via terminal 5 (rotate right- default) or terminal 6 (rotate left- default) — see parameters

P051 to P055 and P356.

(2) If output frequency (P001 = 0) is selected as the display, the corresponding setpoint is flashed on the display approximately every 1.5 seconds while the inverter is stopped.

(3) The inverter is programmed at the factory for standard applications on Siemens standard motors.

When using other motors it is necessary to enter the specifications from the motor’s rating plate into parameters P080 to P085 (see Figure 4.2.1). Note: Access to these parameters is not possible

4.2.2 Initial Testing

1. Check that all cables have been connected correctly (see section 2 or 3 ) and that all relevant product and plant/location safety precautions have been complied with.

2. Apply mains power to the inverter.

3. Ensure that it is safe to start the motor. Press the RUN button on the inverter. The display will change to 5.0 and the motor shaft will begin to turn. It will take 1 second for the inverter to ramp-up to 5 Hz.

4. Check that the motor rotates in the direction required. Press the FORWARD / REVERSE button if necessary.

5. Press the Stop button. The display will change to 0.0 and the motor will slow down, achieving a complete stop after 1 second.

4.2.3 Basic Operation — 10 Step Guide

The basic method of setting up the inverter for use is described below. This method uses a digital frequency setpoint and requires only the minimum number of parameters to be changed from their default settings. It assumes that a standard Siemens four-pole motor is connected to the inverter (see section 4.2.1 if another

motor type is being used).

Step/Action

1. Apply mains power to the inverter.

The display will alternate between the actual frequency (0.0 Hz) and the requested frequency setpoint (5.0 Hz default).

Button Display

2. Press the parameterisation button.

3. Press the

∆

button until parameter P005 is displayed.

4. Press P to display the present frequency setpoint (5 Hz is the factory default setting).

5. Press the

∆

button to set the desired frequency setpoint

(e.g. 35 Hz).

6. Press P to lock the setting into memory.

7. Press the

∇

button to return to P000.

8. Press P to exit the parameterisation procedure.

The display will alternate between the present output frequency and the frequency setpoint.

9. Start the inverter by pressing the RUN button.

The motor shaft will start to turn and the display will show that the inverter is ramping up to the setpoint of 35 Hz.

Note

The setpoint will be achieved after 7 seconds (default ramp-up time, defined by P002 is 10s to reach 50 Hz, the default maximum motor frequency, P013).

If required, the motor’s speed (i.e. frequency) can be varied directly by using the

∆ ∇

buttons. (Set P011 to 001 to enable the new frequency setting to be retained in memory during periods when the inverter is not running.)

10. Switch the inverter off by pressing the STOP button.(see section 5.4)

The motor will slow down and come to a controlled stop.

Note

Full stop will be achieved after 7 seconds (default ramp-down time, defined by P003 is 10 s from 50 Hz, the default value P013).

003 to enable all parameters to be adjusted.

Set parameter P006 to 001 to specify analogue setpoint.

Set parameter P007 to 000 to specify digital input and disable the front panel controls.

Set parameters P021 and P022 to specify the minimum and maximum output frequency settings.

Set parameters P080 to P085 in accordance with the rating plate on the motor (see Figure 4.2.1).

Set the external on/off switch to ON. Turn the potentiometer (or adjust the analogue input control voltage) until the desired frequency is displayed on the inverter.

5.3 Motor Control Modes

The MICROMASTER Vector and MIDIMASTER Vector inverters have four different modes of operation which control the relationship between the voltage supplied by the inverter and the speed of the motor. The motor control mode of operation is selected at P077:

•

Linear voltage/frequency Operation.

•

Flux Current Control (FCC) which is used to maintain full flux conditions in the motor.

•

Quadratic voltage/frequency relationship which is used for pumps and fans.

•

Sensorless Vector. The inverter calculates the changes required in output voltage to maintain the desired motor speed.

These modes are described in more detail below.

G85139-H1751-U529-D1

4/8/99 36

5. OPERATING MODES English

5.3.1 Linear Voltage to Frequency (V/f) (P077 = 0 or 2)

This mode is used for synchronous motors or motors connected in parallel. Each motor should be installed with a thermal overload relay if two or more motors are driven simultaneously by the inverter.

In many cases, when default factory parameters are used, the default stator resistance set in P089 will generally suit the default power rating set in P085. Should the inverter and motor ratings differ, an automatic

Stator Resistance calibration should be performed by setting P088 =1. Continuous Boost (P078) and Starting

Boost (P079) are dependent on the value of Stator Resistance — too high a value may cause overcurrent trips or motor overheating.

5.3.2 Flux Current Control (FCC) Operation (P077 = 1)

Flux Current Control operates by monitoring and maintaining the motor flux current continuously. This ensures that the best performance and efficiency are obtained. FCC is not as complex as SVC, and therefore is easier to set up and operate.

Note: This mode can result in reduced power consumption.

5.3.3 Sensorless Vector Control (SVC) Operation (P077 = 3)

When SVC operating mode is selected (P077=3), the inverter uses an internal mathematical model of the motor, together with accurate current sensing, to calculate the position and speed of the rotor. It is therefore able to optimise the applied voltage and frequency to the motor to give improved performance.

Figure 5.3.3 : MICROMASTER Vector sensorless Vector operation

Although there is no position or speed feedback from the motor, the control system is a closed loop system because it compares the internal motor model performance with the desired performance. The system must therefore be carefully set up and stabilised for best performance.

Setting up SVC Operation

1. Set the correct Motor parameter settings in Parameters P080 to P085.

2. Select Sensorless Vector Operating mode P077 = 3

3. Ensure that the motor is cold and apply a run command. The display will show CAL to indicate that it is measuring the motor stator resistance. After a few seconds the motor will run. Calibration only occurs the first time that a run command is given following P077 being set to 3. It can be forced by changing P077 from SVC operation and back again, or by selecting P088 =1 (Stator Resistance Calibration). Interrupting the calibration process by disconnecting the power or removing the run command may give erroneous

English 5. OPERATING MODES

results and calibration should be repeated. If motor parameters are changed recalibration is also recommended.

Like any control system, SVC must be stabilised by setting the Gain (P386) and Integral (P387) terms.

Actual values and setting up is determined by testing, but the following procedure is suggested:

Whilst the inverter is operating under typical conditions, increase the value of P386, the loop gain, until the first signs of speed instability occur. The setting should then be reduced slightly

(approx. 10%) until stability is restored. As a guide, the optimum setting required will be proportional to the load inertia.

For example: P386 = Load inertia + motor shaft inertia

motor shaft inertia

P387, the integral term, may now be adjusted. Again, whilst operating the inverter under typical conditions, increment this parameter until the first signs of speed instability occur. The setting should then be reduced slightly (approx. 30%) until stability is restored.

If fault code F016 occurs, this indicates that SVC is unstable and further adjustment or recalibration is needed.

F001, DC link overvoltage can also be caused by instability in SVC operating mode.

For further information concerning SVC operation refer to Application Note “Sensorless Vector Control”, which may be obtained from http://www.con.siemens.co.uk or a Siemens Sales Office.

Note: This mode gives the best flux control and higher torque.

5.4 Stopping the Motor

Stopping can be achieved in several ways:

•

Cancelling the ON command on the terminals or pressing the OFF button (O) on the front panel causes the inverter to Ramp-down at the selected Ramp-down rate (see P003).

•

OFF2 — operation causes the motor to coast to a standstill (parameters P051 to P055 or P356 set to 4).

•

OFF3 — operation causes rapid braking (parameters P051 to P055 or P356 set to 5).

•

DC injection braking up to 250% produces more effective braking to provide a quicker stop after cancellation of the ON command (see P073).

•

Resistive braking for MMV (see parameter P075).

•

Compound braking (see P066)

5.5 If the Motor Does Not Start Up

If the display shows a fault code, refer to section 7.

If the motor does not start up when the ON command has been given, check that the ON command is valid, check if a frequency setpoint has been entered in P005 and check that the motor specifications have been entered correctly under parameters P080 to P085.

If the inverter is configured for operation via the front panel (P007 = 001) and the motor does not start when the

RUN button is pressed, check that P121 = 001 (RUN button enabled).

If the motor does not run after parameters have been changed accidentally, reset the inverter to the factory default parameter values by setting parameter P944 to 1 and then pressing P.

5.6 Local and Remote Control

The inverter can be controlled either locally (default), or remotely via a USS data line connected to the internal interface terminals (24 and 25) or to the RS485 D-type connector on the front panel. (Refer to parameter P910 in section 6 for the available remote control options.)

When local control is used, the inverter can only be controlled via the front panel or the control terminals.

Control commands, setpoints or parameter changes received via the RS485 interface have no effect.

G85139-H1751-U529-D1

4/8/99 38

5. OPERATING MODES English

For remote control, the serial interface is designed as a 2-wire connection for bi-directional data transmission.

Refer to parameter P910 in section 6 for the available remote control options.

Note: Only one RS485 connection is allowed. Use either the front panel D-type interface [e.g. to connect an

Clear Text Display(OPM2)] or terminals 24 and 25, but not both.

When operating via remote control the inverter will not accept control commands from the terminals. Exception:

OFF2 or OFF3 can be activated via parameters P051 to P055 and P356 (see section 6).

Several inverters can be connected to an external control unit at the same time. The inverters can be addressed individually.

Note: If the inverter has been set up to operate via the serial link but does not run when an ON command is received, try reversing the connections to terminals 24 and 25 .

5.7 Closed Loop Control

5.7.1 General Description

The MICROMASTER provides a PID control function for closed loop control (see Figure 5.7.1). PID control is ideal for temperature or pressure control, or other applications where the controlled variable changes slowly or where transient errors are not critical. This control loop is not suitable for use in systems where fast response times are required. When closed loop process control is enabled (P201 = 001), all setpoints are calibrated between zero and 100%, i.e. a setpoint of 50.0 = 50%.

5.7.2 Hardware Set-up

Make sure that the DIP selector switches 4 and 5 are correctly set (see Figure 4.1.2) and in agreement with

P323 for unipolar voltage or current feedback signal inputs. Connect the external feedback transducer between control terminals 10 and 11 (analogue input 2). This analogue input accepts a 0/2 — 10 V or a 0/4 — 20 mA input signal (determined by the setting of the DIP selector switches 4 and 5 and P323), has 10-bit resolution and permits a differential (floating) input. 15 V dc power for the feedback transducer can be supplied from terminal 9 on the control block.

5.7.3 Parameter Settings

Closed loop process control cannot be used unless P201 is first set to 001. Most of the parameters associated with closed loop process control are shown in Figure 5.7.1. Other parameters which are also associated with closed loop process control are as follows:

P010 (only if P001 = 1, 4, 5, 7 or 9)

P061 (value = 012 or 013)

P220

Descriptions of all closed loop process control parameters are provided in section 6. For detailed information about PID operation, refer to the application note “Closed Loop Control”, which may be obtained from

http://www.con.siemens.co.uk or a Siemens sales office.

6. SYSTEM PARAMETERS

Parameters can be changed and set using the keypad on the front panel (see Figure 4.1.1) to adjust the desired properties of the inverter, such as ramp times, minimum and maximum frequencies, etc. The parameter numbers selected and the setting of the parameter values are indicated on the four digit LED display.

Note: If the

∆

∇

button is pressed momentarily, the values change step by step. If the button is pressed for a longer time, the values scroll through rapidly.

Access to parameters is determined by the value set in P009. Make sure that the key parameters necessary for the application have been programmed.

Note: In the following parameter table:

‘

•

’ Indicates parameters that can be changed during operation.

‘¶¶¶’ Indicates that the value of this factory setting depends on the rating of the inverter.

Increased Parameter Resolution

To increase the resolution to 0.01 when changing frequency parameters, instead of pressing P momentarily to return to the parameter display, keep the button pressed until the display changes to ‘- -.n0’ (n = the current tenths value, e.g. if the parameter value = ‘055.8’ then n = 8). Press

∆

∇

to change the value (all values between .00 and .99 are valid) and then press P twice to return to the parameter display.

Resetting to Factory Defaults

If parameters are changed accidentally, all parameters can be reset to their default values by setting parameter

P944 to 1 and then pressing P.

This displays the output selected in P001.

In the event of a failure, the relevant fault code (Fnnn) is displayed

(see section 7) or the display flashes in the event of a warning (see

P931) or If output frequency has been selected (P001 = 0) and the inverter is in stand-by mode, the display alternates between the setpoint frequency and the actual output frequency which is zero Hz.

Notes: 1. The display can be scaled via P010.

2. When the inverter is operating in Sensorless Vector

Control mode (P077 = 3) the display shows actual rotor /

shaft speed in Hz. When the inverter is operating in V/f or

FCC modes (P077 = 0, 1 or 2) the display shows inverter output frequency in Hz.

WARNING: In Sensorless Vector Control mode (P077

= 3) the display shows 50Hz when a 4-pole motor is rotating at 1500rpm which may be slightly higher than the nominal speed shown on the motor rating plate.

This is the time taken for the motor to accelerate from standstill to the maximum frequency as set in P013. Setting the Ramp-up time too short can cause the inverter to trip (fault code F002 — overcurrent).

Note: The smoothing curve for deceleration is also affected by the

Sets the frequency that the inverter will run at when operated in digital mode. Only effective if P006 = 0 or 3.

Selects the mode of control of the frequency setpoint for the inverter.

0 = Digital motorised potentiometer. The inverter runs at the frequency set in P005 and can be controlled with the

∆

and

∇ pushbuttons (motorised potentiometer). Alternatively, if P007 is set to zero, the frequency may be increased or decreased by setting any two of the digital inputs (P051 to P055 or P356) to values of 11 and 12.

1 = Analogue. Control via analogue input signal.

2 = Fixed frequency. Fixed frequency is only selected if the value of at least one of the digital inputs (P051 to P055 or

P356) = 6 17 or 18.

3 = Digital setpoint addition. Requested frequency = digital frequency (P005) + fixed frequencies (P041 to P044, P046 to P049) as selected.

Notes: (1) If P006 = 1 and the inverter is set up for operation via the serial link, the analogue inputs remain active.

(2) Motorised potentiometer setpoints via digital inputs are stored upon power-down when P011 = 1.

0 = RUN, JOG and REVERSE are disabled. Control is via digital inputs (see parameters P051 — P055 and P356).

∆

and

∇

may still be used to control frequency provided that P124 = 1 and a digital input has not been selected to perform this function.

1 = Front panel buttons can be selectively enabled or disabled depending on the setting of parameters P121 — P124.

Note: The digital inputs for RUN, JOG and increase/decrease frequency are disabled.

Determines which parameters can be adjusted:

0 = Only parameters from P001 to P009 can be read/set.

1 = Parameters from P001 to P009 can be set and all other parameters can only be read.

2 = All parameters can be read/set but P009 automatically resets to 0 when power is removed.

3 = All parameters can be read/set.

CAUTION: To maintain stable operation when in sensorless vector control mode (P077=3), the maximum motor frequency (P013), should not exceed 3x nominal rating plate motor frequency (P081).

A skip frequency can be set with this parameter to avoid the effects of resonance of the inverter. Frequencies within +/- (the value of P019) of this setting are suppressed. Stationary operation is not possible within this suppressed frequency range — the range is just passed through. Setting P014=0 disables this function.

Setting this parameter to ‘1’ enables the inverter to restart automatically after a mains break or ‘brownout’, provided the external run/stop switch, connected to a digital input, is still closed, P007 = 0 and P910 = 0, 2 or 4.

0 = Disabled

1 = Automatic restart

P016

•

Start on the fly 0 — 4

[0]

Allows the inverter to start onto a spinning motor.

Under normal circumstances the inverter runs the motor up from 0 Hz.

However, if the motor is still spinning or is being driven by the load, it will undergo braking before running back up to the setpoint — this can cause an overcurrent trip. By using a flying restart, the inverter ‘homes in’ on the motor’s speed and runs it up from that speed to the setpoint. (Note: If the motor has stopped or is rotating slowly, some ‘rocking’ may occur as the inverter senses the direction of rotation prior to restarting.)

0 = Normal restart

1 = Flying restart after power up, fault or OFF2 ( if P018 = 1).

2 = Flying restart every time (useful in circumstances where the motor can be driven by the load).

3 = As P016 = 1 except that the inverter will only attempt to restart the motor in the direction of the requested setpoint.

The motor is prevented from ‘rocking’ backwards and forwards during the initial frequency scan.

4 = As P016 = 2 except that the inverter will only attempt to restart the motor in the direction of the requested setpoint.

The motor is prevented from ‘rocking’ backwards and forwards during the initial frequency scan.

Note:

For MIDIMASTER Vector units, it is recommended that if

P016 > 0 then P018 should be set to ‘1’. This will ensure correct re-starting if the inverter fails to re-synchronise on the initial attempt.

IMPORTANT:

When P016 > 0, care must be taken to set up the motor nameplate data (parameters P080 toP085) and to perform an auto stator resistance calibration (P088=1) on a cold motor. Recommended maximum operating frequency should be less than 120 Hz.

Jogging is used to advance the motor by small amounts. It is controlled via the JOG button or with a non-latching switch on one of the digital inputs (P051 to P055 and P356).

If jog right is enabled for one if these digital inputs (e.g. P051-55 or P356 =7) or if the Job Button is pressed this parameter controls the frequency at which the inverter will run when the switch is closed. Unlike other setpoints, it can be set lower than the minimum frequency.

If jog left is enabled (e.g. P051-55 or P356 = 8), this parameter controls the frequency at which the inverter will run when the switch is closed. Unlike other setpoints, it can be set lower than the minimum frequency.

This is the time taken to accelerate from 0 Hz to maximum frequency (P013) for jog functions. It is not the time taken to accelerate from 0 Hz to the jog frequency.

If one of the digital inputs is programmed to select jog ramp times, the corresponding digital input can be used to select the ramp time set by this parameter instead of the normal Ramp-up time set by P002.

This is the time taken to decelerate from maximum frequency (P013) to 0 Hz for jog functions. It is not the time taken to decelerate from the jog frequency to 0 Hz.

If one of the digital inputs is programmed to select jog ramp times, the corresponding digital input can be used to select the ramp time set by this parameter, instead of the normal Ramp-down time set by

Notes: (1) Settings for P063 and P064 should be slightly longer than the actual time taken for the external brake to apply and release respectively

(2) Setting P063 or P064 to too high a value, especially with P012 set to a high value, can cause an overcurrent warning or trip as the inverter attempts to turn a locked motor shaft.

This parameter is used when P061 or P062 = 9. The relay switches on when the motor current is greater than the value of P065 and switches off when the current falls to 90% of the value of P065 (hysteresis).

The inverter can estimate the amount of slip in an asynchronous motor at varying loads and increase its output frequency to compensate. This parameter ‘fine tunes’ the compensation for different motors in the range 0 — 200% of the calculated slip.

Note: This feature is not active and is not necessary when in

Sensorless Vector Control (P077=3).

WARNING: This parameter must be set to zero when using synchronous motors or motors that are connected in parallel or over-compensation can cause instability.

0 — 499 — This limits the slip of the motor to prevent ‘pull-out’ (stalling), which can occur if slip is allowed to increase indefinitely.

When the slip limit is reached, the inverter reduces frequency to keep the level of slip below this limit.

500 — Disables slip limit warning

This rapidly stops the motor by applying a DC braking current and holds the shaft stationary until the end of the braking period. Additional heat is generated within the motor. Braking is effective for the period of time set by P003.

The DC brake can be activated using DIN1 to DIN6 (see P051 to P055

and P356).

WARNING: Frequent use of long periods of dc injection braking can cause the motor to overheat.

If DC injection braking is enabled via a digital input then DC current is applied for as long as the digital input is high. This causes heating of the motor.

Note: If P076 = 4, 5, 6 or 7 then derating does not occur on the above inverters.

Note:

On 230V units of 30kW and above, 400V units of 45kW and above, and 575V units of 22kW and above, P076 can only be set to 4, 5, 6 or 7 (4kHz or 2kHz only).

The switching frequency will automatically be reduced if the inverter internal protection detects an excessive heat sink temperature. The switching frequency will automatically be returned to the setting once this temperature returns to normal.

Controls the relationship between the speed of the motor and the voltage supplied by the inverter. One of four modes can be selected:

0 = V/f curve

1 = FCC control

2 = Quadratic V/f

3 = Vector Control

Note: When Sensorless Vector Control is selected (P077 = 3), P088 will automatically be set to 1, so that on first run-up, the inverter will measure the stator resistance of the motor and calculate motor constants from the rating plate data in P080 to P085.

For many applications it is necessary to increase low frequency torque.

This parameter sets the start-up current at 0 Hz to adjust the available torque for low frequency operation. 100% setting will produce rated motor current (P083) at low frequencies.

WARNING: If P078 is set too high, overheating of the motor and/or an overcurrent trip (F002) can occur.

For drives which require a high initial starting torque, it is possible to set an additional current (added to the setting in P078) during ramp duration (P002). This is only effective during initial start up and until the frequency setpoint is reached.

WARNING: This increase is in addition to P078, but the total is limited to 250%.

Defines the motor overload current as a % of the Nominal motor current (P083) allowed for up to one minute.

With this parameter and P186, the motor current can be limited and overheating of the motor prevented. If the value set in P083 is exceeded for one minute, (or longer if the overload is small) , the output frequency is reduced until the current falls to that set in P083.

The inverter display flashes as a warning indication but the inverter does not trip. The inverter can be made to trip using P074.

Note: The maximum value that P086 can be set to is automatically limited by the rating of the inverter.

0 = Disabled

1 = External PTC enabled

Note:

If motor thermal protection is required, then an external PTC must be used and P087 = 1. If P087 = 1 and the PTC input goes high then the inverter will trip (fault code F004 displayed).

The motor stator resistance is used in the inverter’s internal current monitoring calculations. When P088 is set to ‘1’ and the RUN button is pressed, the inverter performs an automatic measurement of motor stator resistance; stores it in P089 and then resets P088 to ‘0’.

If the measured resistance is too high for the size of inverter (e.g.

motor not connected or unusually small motor connected), the inverter will trip (fault code F188) and will leave P088 set to ‘1’. If this happens, set P089 manually and then set P088 to ‘0’.

Can be used instead of P088 to set the motor stator resistance manually. The value entered should be the resistance measured across any two motor phases.

WARNING: The measurement should be made at the inverter terminals with power off and cold motor.

Note:

If the value of P089 is too high then an overcurrent trip(F002) may occur.

Up to 31 inverters can be connected via the serial link and controlled by a computer or PLC using the USS serial bus protocol. This parameter sets a unique address for the inverter.

Read only. This parameter stores the last recorded fault code prior to that stored in P142.

This parameter defines the instantaneous motor current limit as a % of the nominal motor current (P083). If the output current reaches this limit for three seconds, the inverter automatically reduces the current to the limit set in P086.

Note: * The maximum value that can be set for P186 is automatically limited by the rating of the inverter.

Torque limit operation is available, from 5Hz to 50Hz, when using

Vector Control mode (P077=3). The motor torque produced is a function of motor current. If P186 and P086 are equal, the current limit function can effectively be used as a torque limit.

1 = 2 V to 10 V/ 4 to 20 mA Unipolar input

2 = 2 V to 10 V/ 4 to 20 mA Unipolar input with controlled start / stop when using analogue input control.

Note:

Setting P323 = 2 will not work unless the inverter is under full local control (i.e. P910 = 0 or 4) and V

≥

1 V or 2mA.

WARNING:The inverter will automatically start when voltage goes above 1V or 2mA. This equally applies to both analogue and digital control (i.e. P006 = 0 or 1)

Control function selection, DIN 6

See P051 — P055 for description.

To optimise the dynamic performance of the vector control this parameter should be incremented whilst the inverter is operating under typical conditions until the first signs of speed instability occur. The setting should then be reduced slightly (approx. 10%) until stability is restored. In general, the optimum setting required will be proportional to the load inertia. If this setting is too low or too high, rapid load changes may result in DC link overvoltage trips (F001) and/or unstable vector control.

See section 5.3.3 for further information .

Note: P386 = Load inertia + motor shaft inertia

motor shaft inertia

P386 must be optimised before adjusting P387. Whilst operating the inverter under typical conditions, increment this parameter until the first signs of speed instability occur. The setting should then be reduced slightly (approx. 30%) until stability is restored.

9.1 Application Example

Set-up procedure for a simple application

Motor: 230 V

1.5 kW output power

Application requirements: Setpoint adjustable via potentiometer 0 — 50 Hz

Ramp-up from 0 to 50 Hz in 15 seconds

Ramp-down from 50 to 0 Hz in 20 seconds

MMV150 (6SE3216-8BB40) Inverter used:

Settings: P009 = 2 (all parameters can be altered)

P080 — P085 = values given on motor rating plate

P006 = 1 (analogue input)

P002 = 15 (Ramp-up time)

P003 = 20 (Ramp-down time)

This application is now to be modified as follows:

220

Operation of motor up to 75 Hz

(voltage/frequency curve is linear up to 50 Hz).

Motor potentiometer setpoint in addition to analogue setpoint .

Use of analogue setpoint at maximum 10 Hz.

English

75 f (Hz)

Settings: P009 = 2 (all parameters can be altered)

P013 = 75 (maximum motor frequency in Hz)

P006 = 2 (setpoint via motor potentiometer or fixed setpoint)

P024 = 1 (analogue setpoint is added)

P022 = 10 (maximum analogue setpoint at 10 V = 10 Hz)

9.2 USS Status Codes

The following list gives the meaning of status codes displayed on the front panel of the inverter when the serial link is in use and parameter P001 is set to 006:

English 9. SUPPLEMENTARY INFORMATION

9.3 Electro-Magnetic Compatibility (EMC)

All manufacturers / assemblers of electrical apparatus which performs a complete intrinsic function which is placed on the market as a single unit intended for the end user must comply with the EMC directive

EEC/89/336 after January 1996. There are three routes by which the manufacturer/assembler can demonstrate compliance:

Self-Certification

This is a manufacturer’s declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only standards which have been officially published in the Official Journal of the European Community can be cited in the manufacturer’s declaration.

Technical Construction File

A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ‘Competent Body’ appointed by the appropriate European government organisation. This approach allows the use of standards which are still in preparation.

EC Type-Examination Certificate

This approach is only applicable to radio communication transmitting apparatus.

The MICROMASTER Vector and MIDIMASTER Vector units do not have an intrinsic function until connected with other components (e.g. a motor). Therefore, the basic units are not allowed to be CE marked for compliance with the EMC directive. However, full details are provided below of the EMC performance characteristics of the products when they are installed in accordance with the wiring recommendations in section 1.2.

Range

Description / Notes

[Default]

0 — 3

Controls the relationship between the speed of the motor and the voltage

supplied by the inverter. One of four modes can be selected:

(1)

0 = V/f curve

1 = FCC control

2 = Quadratic V/f

3 = Vector Control

Note: When Sensorless Vector Control is selected (P077 = 3), P088 will

automatically be set to 1, so that on first run-up, the inverter will

measure the stator resistance of the motor and calculate motor

constants from the rating plate data in P080 to P085.

For many applications it is necessary to increase low frequency torque. This

0 — 250

parameter sets the start-up current at 0 Hz to adjust the available torque for low

[100]

frequency operation. 100% setting will produce rated motor current (P083) at

[100]

low frequencies.

[50]

WARNING:

0 — 250

For drives which require a high initial starting torque, it is possible to set an

[0]

additional current (added to the setting in P078) during ramp duration (P002).

This is only effective during initial start up and until the frequency setpoint is

reached.

WARNING:

0.00-1.00

[¶¶¶]

If efficiency is shown on the motor rating plate, calculate the power factor as

follows: pf =

If neither power factor nor efficiency are shown on the motor rating plate — set

P080 = 0.

Notes:

[¶¶¶]

1 These parameters P080 to P085 must be set for the particular motor used.

Read the figures from the motor rating plate (see Figure 4.2..1 ).

2 It will be necessary to perform an automatic calibration (P088 = 1) if P080 to

0.1-300.0

[¶¶¶]

0 — 250

Defines the motor overload current as a % of the Nominal motor current (P083)

allowed for up to one minute.

[150]

With this parameter and P186, the motor current can be limited and

overheating of the motor prevented. If the value set in P083 is exceeded for

one minute, (or longer if the overload is small) , the output frequency is reduced

until the current falls to that set in P083. The inverter display flashes as a

warning indication but the inverter does not trip. The inverter can be made to

trip using P074.

Note:

The maximum value that P086 can be set to is automatically limited by

the rating of the inverter. Further, the power can be automatically

reduced for pulse frequencies which differ from the factory setting

(refer to P076)

0 — 1

0 = Disabled

1 = External PTC enabled

[0]

Note:

If motor thermal protection is required, then an external PTC must

be used and P087 = 1. If P087 = 1 and the PTC input goes high

then the inverter will trip (fault code F004 displayed).

6. SYSTEM PARAMETERS

hp x 746

1.732 x efficiency x nom. volts x nom. amps

If P078 is set too high, overheating of the motor and/or

an overcurrent trip (F002) can occur.

This increase is in addition to P078, but the total is

limited to 250%.
