OC1 Overcurrent in motor cable

What does 0011 mean?

An overcurrent (Ia > 2.25 x IN) has occurred in the motor cable, detected by hardware monitoring. This can be caused by a short circuit in the motor cable, excessive capacitive charging current of the motor cable, or acceleration/deceleration times that are too short for the load. It can also indicate a missing mains phase or an encoder wiring issue.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Increase the gain (P component) of the Imax controller (C0075).

2. 4

   Reduce the integral-action time (integral action component) of the Imax controller (C0076).

3. 5

   If the drive is connected to a coasting machine, activate the flying restart circuit.

4. 6

   If an encoder error is suspected, check the wiring of the encoder, especially verifying that tracks during encoder feedback of motor speed are not interchanged.
