Function:
Min - Max motor frequency: 20-1000 Hz.
Select the motor frequency value from the
motor nameplate data. If a value different
from 50 Hz or 60 Hz is selected, it is
necessary to adapt the load independent
settings in 1-50 Motor Magnetisation at Zero
Speed to 1-53 Model Shift Frequency. For 87
Hz operation with 230/400 V motors, set the
nameplate data for 230 V/50 Hz. Adapt
4-13 Motor Speed High Limit [RPM] and
3-03 Maximum Reference to the 87 Hz
application.
Function:
[0.10 - Enter the nominal motor current
value from the motor nameplate
data. This data is used for
calculating motor torque, motor
thermal protection etc.
Function:
[100 - 60000 Enter the nominal motor speed
value from the motor nameplate
data. This data is used for
calculating automatic motor
compensations.

Function:
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters (1-30 Stator
Resistance (Rs) to 1-35 Main Reactance (Xh)) at
motor standstill.
Activate the AMA function by pressing [Hand
on] after selecting [1] or [2]. See also
3.4 Automatic Motor Adaptation. After a
normal sequence, the display will read: "Press
[OK] to finish AMA". After pressing [OK] the
frequency converter is ready for operation.
This parameter cannot be adjusted while the
motor is running.
Performs AMA of the stator resistance R
rotor resistance R , the stator leakage
r
reactance X , the rotor leakage reactance X
1
and the main reactance X
Performs a reduced AMA of the stator
resistance R in the system only. Select this
s
option if an LC filter is used between the
frequency converter and the motor.
