Motor Phase Failure

What does LP1 mean?

One or more motor phases have failed, or the motor current has dropped below an expected minimum. This could be due to a disconnected cable, an open circuit within the motor, or incorrect parameter settings. Operating with a phase failure can cause motor overheating, damage to the drive, and inefficient operation.

Complete Troubleshooting Guide

1. 1

   Inspect all motor cables for damage, loose connections, or open circuits.

2. 2

   Verify the 'V min' setting (minimum voltage threshold) to ensure it is correctly configured for the motor.

3. 3

   Confirm the motor is connected with appropriate power for the drive, or adapt the motor settings under parameter C599 if necessary.
