VLT® Decentral Drive FCD 302
Operating Guide
Automatic motor adaptation (AMA) is a procedure that optimizes compatibility between the drive and the motor.
•
The drive builds a mathematical model of the motor for regulating output motor current. The procedure also tests the input
phase balance of electrical power. It compares the motor characteristics with the data entered in parameters 1-20 to 1-25.
•
The motor shaft does not turn and no harm is done to the motor while running AMA.
•
Some motors may be unable to run the complete version of the test. In that case, select [2] Enable reduced AMA.
•
If an output filter is connected to the motor, select [2] Enable reduced AMA.
•
If warnings or alarms occur, see
•
Run this procedure on a cold motor for best results.
