Motor Phase Failure

What does FAILURE OF MOTOR PHASE Ax mean?

A failure has been detected in one of the motor phases for the specified axis (Ax). This typically indicates an open circuit, loose connection, or an imbalance in the motor's power supply.

1. 1

   Check the motor cable for the specified axis (Ax) for loose connections or breaks in individual phases.

2. 2

   Verify continuity of each motor phase from the KSD output to the motor terminals.

3. 3

   Check the motor itself for internal winding failures or open circuits.
