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.

    Frequently Asked Questions Section 1-4 Frequently Asked Questions Q. What is the main advantage in using an inverter to drive a motor, com- pared to alternative solutions? A. An inverter can vary the motor speed with very little loss of efficiency, unlike mechanical or hydraulic speed control solutions.

  • Page 45
    Q. How many poles should the motor have? A. Omron inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of the poles, the slower the top motor speed will be, but it will have higher torque at the base speed.

    Appendix D CE-EMC Installation Guidelines CE-EMC Installation Guidelines You are required to satisfy the EMC directive (2004/108/EC) when using an MX2 inverter in an EU country. To satisfy the EMC directive and to comply with standard, you need to use a dedicated EMC filter suitable for each model, and follow the guidelines in this section.

  • Page 400
    CE-EMC Installation Guidelines Section D-1 5. Use shielded wiring for the motor cable and all analog and digital control lines. • Allow the effective shield area of these lines to remain as large as possi- ble; i.e., do not strip away the shield (screen) further away from the cable end than absolutely necessary.
  • Page 401
    CE-EMC Installation Guidelines Section D-1 7. Minimize the distance between an interference source and an interference sink (interference- threatened device), thereby decreasing the effect of the emitted interference on the interference sink. • You should use only interference-free devices and maintain a minimum distance of 0.25 m from the adjustable frequency inverter.
