Omron Electronics 3G3MX2 series mid-range micro drives

The Omron 3G3MX2 series mid-range micro drives are available in 240 and 480 V versions, and in power ranges from 0.1 to 15 kW. With sensorless vector control functionality and built-in safety inputs, the 3G3MX2 is suitable for constant torque conveyor and mixing applications and variable torque fans and pumps.

The series provides smooth control down to zero speed, precise operation for fast cyclic operations and torque control capability in open loop. The 3G3MX2 also delivers functionality for machine control such as positioning, speed synchronisation and logic programming. The auto-tuning capability sets the AC drive for smooth and safe operations by entering the power rating of the motor, making commissioning trouble free.

The series delivers 200% starting torque near standstill (0.5 Hz) and can operate in torque control in open loop mode, providing a cost-effective alternative to closed loop AC vector drives.

The drives easily integrate into new and existing safety systems. Safety circuits embedded in the drives provide safe torque off operator protection conforming to ISO 13849-1, Cat 3. This removes power from the motor allowing it to coast to a stop while the drive itself is still powered up.

The series has two safety inputs and an external device monitoring (EDM) output. The safety inputs can be linked from one inverter to another without additional safety relays and no external contactors are required on the motor side allowing simpler wiring for the user. The EDM output confirms the safety status of the AC drive.
