Output phase supervision

What does 11 mean?

The current measurement system has detected that there is no current flowing in one of the motor phases. This typically indicates an open circuit condition in the motor cables or within the motor windings, which can lead to motor damage or uncontrolled operation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Perform an insulation resistance test (megger test) between each motor phase and the motor frame to check for ground faults.
