AMA: Parameter out of range
Danfoss · VLT HVAC Drive High Power
What does 55 mean?
The Automatic Motor Adaptation (AMA) cannot run because one or more parameter values related to the motor are outside of the acceptable range for the AMA algorithm. This indicates an invalid motor configuration that prevents the drive from accurately modeling the motor.
Complete Troubleshooting Guide
- 1
Review all motor data parameters (1-20 to 1-25) for values that might be outside typical operating or permissible ranges.
- 2
Ensure consistency between different motor parameters (e.g., voltage and frequency).
- 3
Consult the drive manual for acceptable ranges for AMA-related parameters.
