If your Omron Inverter displays an overcurrent fault, it could be due to several reasons. It may be caused by a short circuit or ground fault on the drive output side, or the load might be too heavy. Also, check if the acceleration/deceleration times are too short, or if the motor data or V/f pattern settings are incorrect. Avoid switching a magnetic contactor at the output.
