Cause : Over Current comes when drive output current exceeded the overcurrent detection level (approximately 180% of Drive rated output current).

1. Shorted Drive output phase to phase, shorted motor, locked rotor, load too heavy, accel/ decel time too short, contactor on the drive output is opened and closed, a special motor or a motor with a FLA rating larger than drive rated output current.
2. Remove the motor and run the Drive without the motor.
3. Check the motor for a phase-to- phase short.
4. Check the drive for a phase-to- phase short at the output.
5. Verify C1-01 and C1-02 are set correctly.
6. Check load conditions.
