OC: output current of the AC drive exceeds the OC level
1. Extend the accel/decel time
2. Check whether the motor rating and the AC drive rating match up with each other.
3. Check whether there is short-circuit among U-V-W of the AC drive.
4. Check whether the wiring to the motor is short-circuited or grounded.
5. Check whether the screw between the AC drive and the motor is tightened or not.
6. Check whether the motor is over loaded.
