AMA parameter out of range

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.

Complete Troubleshooting Guide

1. 1

   Thoroughly review all motor data parameters (e.g., 1-20 to 1-25) against the motor's nameplate and the drive's specifications.

2. 2

   Ensure that all entered values, such as nominal voltage, current, frequency, and speed, fall within the acceptable ranges defined by the frequency converter.

3. 3

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