What does 55 mean?

During the Automatic Motor Adaptation (AMA) process, one or more motor parameter values were found to be outside the acceptable range for the frequency converter. This prevents AMA from completing and can result from incorrect motor data entry or unusual motor characteristics. The drive cannot perform optimal motor control without successful AMA.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Correct any incorrect or out-of-range parameter values and then attempt to re-run the AMA process.
