Over-current during deceleration (ocd)

Output current exceeds three times of the rated current during deceleration. When ocd occurs, the drive closes the gate of the output immediately, the motor runs freely, and the display shows an ocd error.

1. Increase the deceleration time
2. Increase the deceleration time of S-curve
3. Set auto-acceleration and auto-deceleration parameter (Pr.01-44)
4. Set over-current stall prevention function (Pr.06-03)
5. Replace the drive with a larger capacity mode

The ocd occurs due to the short circuit or ground fault at the output side of the
drive.
Check for possible short circuits between terminals with the electric meter:
B1 corresponds to U, V and W; DC- corresponds to U, V and W;
corresponds to U, V and W.
