Omron 3G3MX2 series multifunction compact inverter

The 3G3MX2 series multifunction compact inverter supports standard induction and permanent magnet motors, and includes an EtherCAT fieldbus system, PID control and built-in safety. Options are available for all of the major open network systems, including EtherCAT, Modbus-RTU, CompoNet and DeviceNet.

The product is suitable for low- to medium-torque applications. It delivers 200% starting torque near standstill (0.5 Hz) and can operate in sensorless vector control mode. This allows the device to be used in applications where closed-loop AC vector drives were previously used.

Category 3 safety is embedded in the unit, according to ISO 13849-1, with dual safety inputs and an external device monitoring (EDM) output. No external contactors on the motor side are required, meaning simple wiring for the user.

All drives in the product range have dual power ratings. These are heavy load (where constant torque is required) and light load for fans and pumps, where the torque can be reduced once the load is in motion. The 3G3MX2 is a drive and position controller in one, suitable for modular machines where moderate positional accuracy is required. Speed synchronisation is also possible, with no additional programming needed.

Specially developed application functionality enables the product to solve simple positioning tasks without the need for an external controller. Users can select up to eight positions, plus home. Alternatively, utilising a flow chart programming tool, users can create programs with up to 1000 lines of code, with up to five tasks running in parallel.
