Function:
data. The default value corresponds to
the nominal rated output of the unit.
Function:
Minimum to maximum motor frequency:
20-1000 Hz.
Select the motor frequency value from the
motor nameplate data. If a value other than
50 Hz or 60 Hz is selected, adapt the load-
independent settings in parameter 1-50 Motor
Magnetisation at Zero Speed to
parameter 1-53 Model Shift Frequency. For 87
Hz operation with 230/400 V motors, set the
nameplate data for 230 V/50 Hz. To run at 87
Hz, adapt parameter 4-13 Motor Speed High
Limit [RPM] and parameter 3-03 Maximum
Reference.
Function:
[ 0.10 - Enter the nominal motor current
value from the motor nameplate
data. The data are used for
calculating torque, motor
protection etc.
Function:
[10 - 60000 Enter the nominal motor speed
value from the motor nameplate
data. The data are used for
calculating motor compensations.

Function:
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, i.e. the parameter is valid for PM and
non-salient SPM motors only.

It is important to set motor parameter group 1-2* Motor
Data correctly, since these form part of the AMA
algorithm. An AMA must be performed to achieve
optimum dynamic motor performance. It may take up to
10 min, depending on the power rating of the motor.
Function:
The AMA function optimises dynamic motor
performance by automatically optimising 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] or [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 frequency
converter is ready for operation.

Motor Data).
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)
for best performance.
Complete AMA cannot be performed on
permanent magnet motors.
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.
For the best adaptation of the frequency
converter, run AMA on a cold motor.
