Controller Overload (Acceleration)

What does OC3 mean?

The controller has experienced an overload condition during acceleration, possibly due to an acceleration time (C0012) that is too short, an improperly dimensioned drive, or issues with the motor/cabling like a defective motor cable or interturn fault. Persistent overloading can lead to drive component degradation and premature failure.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Thoroughly inspect all motor wiring and connections for any defects.

2. 4

   Perform a winding test on the motor to check for interturn faults.
