Programming Guide
Parameter 1-25 Motor Nominal Speed
Table 82: Parameter 1-25 Motor Nominal Speed
1-25 Motor Nominal Speed
Default value: Size related
Conversion index: 67
Enter the nominal motor speed value from the motor nameplate data. The data is used for calculating motor compensations.
n = n − n
m, n s slip
Parameter 1-26 Motor Cont. Rated Torque
Table 83: Parameter 1-26 Motor Cont. Rated Torque
1-26 Motor Cont. Rated Torque
Default value: Size related
Conversion index: -1
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 84: 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)) at motor standstill. Activate the AMA function by pressing [Hand
On] after selecting [1] Enable Complete AMA or [2] Enable Reduced AMA. See also the section Automatic Motor Adaptation in the De-
sign 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.
