What does 51 mean?

The Automatic Motor Tuning (AMT) process detected an incorrect setting for the motor's nominal voltage and/or nominal current parameters. This prevents accurate motor modeling and can lead to suboptimal motor control, protection, and efficiency.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Re-run the Automatic Motor Tuning (AMT) procedure after correcting any identified motor data errors.

  2. 4

    Check if the motor is suitable for the drive's voltage class and that motor parameter ranges are compatible with the drive.
