AMA: Motor Voltage and Current settings incorrect

Danfoss · VLT HVAC Drive High Power

What does 51 mean?

The settings for motor voltage, motor current, and motor power (parameters 1-20 to 1-25) are incorrect or inconsistent, preventing the Automatic Motor Adaptation (AMA) from running accurately. Using incorrect motor data will result in suboptimal drive performance and potentially damage to the motor or drive.

Complete Troubleshooting Guide

  1. 1

    Carefully check and correct the motor nameplate data entered into parameters 1-20 to 1-25.

  2. 2

    Re-attempt the AMA sequence after correcting parameters.
