Automatic Motor Tuning Incorrect Motor

Danfoss · VLT 2800 Variable Speed Drive

What does 54 mean?

The drive is unable to perform Automatic Motor Tuning (AMT) on the connected motor. This indicates a fundamental incompatibility between the motor type and the AMT function, or that the motor parameters are so far off that the tuning cannot proceed. The drive cannot establish proper control without successful tuning.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    If the motor is known to be compatible, consider manually entering motor parameters from a known good source or previous successful setup, then attempt AMT again.
