AMA motor too big

Danfoss · VLT HVAC Basic FC 101

What does ALARM 53 mean?

The motor connected is too large for the Automatic Motor Adaptation (AMA) function to be successfully performed by this frequency converter. The drive may not be adequately sized for the motor, which can lead to inaccurate parameter identification or drive overload.
