  • Page 41 1-3-4 Inverter Input and Three-phase Power The Omron MX2 Series of inverters includes two sub-groups: the 200 V class and the 400V class inverters. The drive described in this manual may be used in either the United States or Europe, although the exact voltage level for com- mercial power may be slightly different from country to country.
  • Page 42 Introduction to Variable-Frequency Drives Section 1-3 The Omron inverter is a rugged and reliable device. The intention is for the inverter to assume the role of controlling power to the motor during all normal operations. Therefore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop).

  • Page 44: Frequently Asked Questions

    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.

You are working with high voltages and high- frequency switching waveforms that are not pure sinusoids. Digital voltmeters will not usually produce reliable readings for these waveforms.
  • Page 312 Maintenance and Inspection Section 6-4 6-4-6 Capacitor Life Curves The DC bus inside the inverter uses a large capacitor as shown in the dia- gram below. The capacitor handles high voltage and current as it smoothes the power for use by the inverter. So, any degradation of the capacitor will affect the performance of the inverter.

    The ability of a controller to execute a procedure that interacts with a load to determine the proper coefficients to use in the control algorithm. Auto-tuning is a common feature of process controllers with PID loops. Omron inverters feature auto tuning to determine motor parameters for optimal commutation.
  • Page 316 Section A-1 Digital Operator Panel For Omron inverters, “digital operator panel” (DOP) refers first to the operator keypad on the front panel of the inverter. It also includes hand-held remote keypads, which connect to the inverter via a cable. Finally, the DOP Profes- sional is a PC-based software simulation of the keypad devices.

Intelligent Terminal A configurable input or output logic function on the Omron inverters. Each ter- minal may be assigned one of several functions. Inverter A device that electronically changes DC to AC current through an alternating process of switching the input to the output, inverted and non-inverted.
  • Page 318 Sensorless Vector Control A technique used in some variable-frequency drives (featured in some other Omron inverter model families) to rotate the force vector in the motor without the use of a shaft position sensor (angular). Benefits include an increase in torque at the lowest speed and the cost savings from the lack of a shaft posi- tion sensor.

    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.

Power supply 1-ph. 200 V Metal plate (earth) The filter is a footprint type, so it is located between the inverter and the metal plate.

    Appendix E Safety (ISO 13849-1) Introduction The Gate Suppress function can be utilized to perform a safe stop according to the EN60204-1, stop category 0 (Uncontrolled stop by power removal). It is designed to meet the requirements of the ISO13849-1, PL=d and IEC61508 SIL 2 only in a system in which EDM signal is monitored by an “external device monitor”.

    ··· http://www.littelfuse.co.jp 216 series 250 VAC, 100 mA (CCC, UL, CSA, SEMKO, CE, VDE) Any external signal voltage connected to the 3G3MX2 must be from a SELV Power. By pressing the emergency stop button, the current to GS1 and GS2 is shut off, and the inverter output is shut off.

  • Page 408: Wiring Example

    Wiring example Section E-6 !Caution Inverter doesn’t block the current flowing into itself when it is not powered. This may cause the closed circuit when two or more inverters are connected to common I/O wiring as shown below to result in unexpected turning on the input.

    27.09.2006 The configuration of and components used in any circuit other than an appropiately pre approved safety module that interfaces with the 3G3MX2 GS1/GS2 and EDM ports must be at least equivalent to CAT 3 PLd under ISO 13849-1:2006 in order to be able to claim an overall CAT 3 PLd for the 3G3MX2 and external circuit combination.
