Cхема подключения питания, двигателя, дискретных и аналоговых входов и выходов.

Элементы пульта оператора

• Светодиод пуска – загорается при подаче команды на запуск двигателя во время начала вращения и отключается при остановке мотора.
• Светодиод программирования – загорается при готовности к изменению значений параметров и отключается в режиме контроля текущих параметров.
• Светодиод активности кнопки пуск – загорается при активированной кнопке и возможности с нее подать команду на запуск мотора.
• Кнопка пуска Run – при нажатии производится запуск двигателя (сначала должен светиться светодиод над кнопкой). Направление вращения двигателя можно задавать через функцию F004.
• Кнопка Stop/Reset – при нажатии производится остановка двигателя (при этом используется значение времени замедления), а также, происходит сброс возникающих ошибок.
• Экран отображения значений – 4-х разрядный, 7-ми сегментный индикатор для программирования и отображения параметров и текущих значений.
• Светодиоды: Hz, A – загораются при отображении на экране частоты или тока, соответственно.
• Светодиод Power – загорается при подаче питания на инвертор.
• Светодиод Alarm – загорается, когда инвертор в состоянии “Сбой”.
• Кнопка цикла – используется для входа в режим программирования, перемещения по группам параметров и функций.
• Кнопки вверх и вниз – используются для перемещения вверх/вниз по списку внутри 1 группы параметров и функций отображаемых на индикаторе и для изменения их значений.
• Кнопка ввода – используется для входа в отображаемый параметр или функцию, для выхода из нее с сохранением установленного значения в памяти EEPROM.

Порядок работы со списком параметров и функций

Коды ошибок

Преобразователи частоты серии МХ2 имеют защиту от перегрузки по току, от повышенного/ пониженного напряжения и много других. При срабатывании защиты отключается выход инвертора и остановка двигателя происходит в режиме свободного выбега. Перезагрузка частотного преобразователя и сброс ошибки производится нажатием кнопки STOP/RESET.

  For use with the phase S grounding, it is recommended to use the Input Noise Filter (Model: 3G3AX-NFI). • OMRON currently plans to support the EMC noise filters for the 3G3MX2-V1 Series. Installing magnetic contactor To shut off the main circuit power supply with a sequence, you can use a magnetic contactor (MC) on the inverter side closer than a molded case circuit breaker (MCCB).

  2 Design Inrush current flow when the inverter power supply is turned ON When the inverter power supply is turned ON, the charging current, which is called inrush current, flows in the main circuit board capacitor. The table below shows the reference values at a power supply voltage of 200 V or 400 V when the power supply impedance is low.
• Page 84
  2 Design Installing input noise filter The inverter performs high-speed output switching, which may cause the noise flow from the inverter to power supply lines that negatively affects on peripheral equipment. Therefore, it is recommended to use an input noise filter to reduce noise flowing out to power supply lines.

  2 Design Harmonic Current Measures and DC/AC Reactor Wiring (+1, P/2) In recent years, there is an increasing concern about harmonic currents generated from industrial machinery. The following provides an overview of harmonics and measures against harmonics implemented in this inverter.

• Page 86: Before Wiring

  2 Design Causes of harmonics • General electrical equipment internally con- Voltage verts AC input power (commercial power) into DC power. At this time, harmonic currents occur because of the difference in the current Time flow direction between AC power and DC power.

  2 Design Measures against radio noise Besides the I/O wires, radio noise is radiated from the inverter itself. This radio noise can be reduced by installing noise filters on both the input and output sides of the inverter and by installing and shielding the inverter body in a grounded iron enclosure etc. Keep the cables between the inverter and the motor as short as possible.

  2 Design External Braking Resistor Connection Terminal (P/+2, RB)/ Regenerative Braking Unit Connection Terminal (P/+2, N/–) When driving a load with a large inertia or a vertical axis, regenerated energy is fed back to the inverter when it is decelerating or generating downward movement. If the amount of regenerative energy exceeds the amount allowable for the inverter, an overvoltage is detected.

  5 Basic Settings Reduced Torque Characteristics (VP 1.7th Power (VC at low speed)) This setting is suitable for fan, pump, and other applications that do not require large torque at low speeds. It provides high efficiency, reduced noise, and vibration, because the output voltage is reduced in the low speed range.

  5 Basic Settings • The free V/f function is disabled by default. Even if you set 02 (Free V/f setting) in the 1st/2nd Control Method (A044/A244), the inverter cannot operate with the free V/f function. • If the free V/f function is enabled, the torque boost function (A041/A241, A042/A242, A043/A243), Base Frequency (A003/A203), and Maximum Frequency (A004/A204) settings are disabled.

  5 Basic Settings Electronic Thermal Characteristics The electronic thermal function enables you to change the overload detection characteristics by setting the 1st/2nd Electronic Thermal Characteristics Selection (b013/b213) according to the motor in use. The reduced torque characteristics and the constant torque characteristics are achieved by setting the reduction factor for each output frequency of the inverter in the basic electronic thermal characteristics.

• Page 195: Constant Torque Characteristics

  5 Basic Settings Constant torque characteristics Use the torque characteristics setting for dedicated inverter motors. Dedicated inverter motors are designed to prevent degradation of the cooling effect that arises as the motor speed increases, except at 5 Hz or less. For constant torque characteristics, the reduction factor is not defined for frequencies of 5 Hz or more.
