Programming Guide
Enter the value from the motor nameplate data. The default value corresponds to the nominal rated output. This parameter is avail-
able when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM, that is, the parameter is valid for PM and non-salient
SPM motors only.
Parameter 1-29 Automatic Motor Adaptation
Table 83: Parameter 1-29 Automatic Motor Adaptation (AMA)
1-29 Automatic Motor Adaptation (AMA)
Default value: [0] Off
Conversion index: –
This parameter cannot be adjsuted while the motor is running.
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced motor parameters (parameter
1-30 Stator Resistance (Rs) to parameter 1-35 Main Reactance (Xh)) on a cold motor at standstill. Activate the AMA function by press-
ing [Hand On] after selecting [1] Enable Complete AMA or [2] Enable Reduced AMA. If an LC filter is used between the drive and the
motor, always select [2] Enable Reduced AMA. See also the section Automatic Motor Adaptation in the Design Guide. After a normal
sequence, the display reads: Press [OK] to finish AMA. After pressing [OK], the drive is ready for operation.
Ensure that a value is set in parameter 14-43 Motor Cosphi before running AMA II.

Do not select this option if an LC filter is used between the drive and the motor. For best performance, it is
recommended to obtain the advanced motor data from the motor manufacturer to enter into parameter
1-31 Rotor Resistance (Rr) through parameter 1-36 Iron Loss Resistance (Rfe). Complete AMA cannot be per-
formed on permanent magnet motors.
