Overcurrent

What does OCF mean?

This fault indicates that the current drawn by the motor has exceeded the drive's maximum permissible limit. Common causes include incorrect drive or motor parameters, excessive mechanical load, or a mechanical locking of the driven equipment. An overcurrent condition can quickly damage both the motor windings and the drive's output power stage (IGBTs).

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect the driven mechanism for any mechanical locking, seized bearings, or other issues preventing free movement.

2. 4

   Ensure the motor and drive are appropriately sized for the application's load requirements.
