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
Parameter type: Option
Setup: All setups
Conversion index: –
Data type: Uint8
Change during operation: False
N O T I C E
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.

Enable Re-
duced AMA
Performs a reduced AMA of the stator resistance R

in the system only. This option is available for standard
asynchronous motors and non-salient PM motors.

II
Performs a reduced AMA of the stator resistance R
s
in the system only. Select this option if an LC filter is
used between the drive and the motor. The AMA II is a variant of AMA, based on the principles of the tor-
que calibration. It is recommended for special motors (for example S3) and high-power motors.
