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.
