Enter the value from the motor nameplate data. The default value corresponds to the nominal rated output. This parameter is available
when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM, [2] PM, salient IPM, [5] SynRM, and [6] PMaSynRM.
1-29 Automatic Motor Adaptation (AMA)
Default value: [0] Off
Setup: All setups
Data type: Uint8
This parameter cannot be adjusted 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 pressing [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.

Description
Performs
• AMA of the stator resistance R
• The rotor resistance R
• The stator leakage reactance X
• The rotor leakage reactance X
• The main reactance X
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 performed on permanent magnet motors.
Performs a reduced AMA of the stator resistance R
only. This option is available for standard asynchronous motors
and non-salient PM motors.
Performs AMA of the stator resistance R
the stator leakage reactance X
and the main reactance X
Performs a reduced AMA of the stator resistance R
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 torque calibration. It is recommended for special
motors (for example S3) and high-power motors.
