1-29 Automatic Motor Adaptation (AMA)
Option:
Function:
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor parameters (
to
) 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.

Note:
•
For the best adaptation of the frequency
converter, run AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
•
AMA cannot be performed on permanent magnet
motors.
