Overcurrent in phase B

What does 4635 mean?

An overcurrent condition has been detected or reported in phase B of the drive or terminal. This indicates that the current flowing through phase B has exceeded the drive's or motor's rated capacity. Potential causes include mechanical overload, a short circuit in the motor or cable, or incorrect motor parameters in the drive, risking damage to the drive and motor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect the motor and its wiring for phase B for any signs of short circuits to ground or between phases.

2. 4

   Measure the motor's insulation resistance and winding resistance to detect faults.
