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

1-29 Automatic Motor Adaptation (AMA)
Option: Function:
The AMA function optimises dynamic motor
performance by automatically optimising 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 the
section Automatic Motor Adaptation in the
Design Guide. After a normal sequence, the
display will read: "Press [OK] to finish AMA".
After pressing the [OK] key the frequency
converter is ready for operation.
