Parameters
1-29 Automatic Motor Adaption (AMA)
Option: Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor 1-30 Stator Resistance (Rs) to
1-35 Main Reactance (Xh) while the motor is
stationary.

Terminal 27 Digital Input (5-12 Terminal

option if an LC filter is used between the
frequency converter and the motor.
NOTICE
When 1-10 Motor Construction is set to [1] PM, non-salient
SPM, the only option available is [2] Enable Reduced AMA.
Activate the AMA function by pressing [Hand On] after
selecting [1] or [2]. After a normal sequence, the display
reads: "Press [OK] to finish AMA". After pressing [OK], the
frequency converter is ready for operation.
NOTICE
•
For the best adaptation of the frequency
converter, run AMA on a cold motor
•
AMA cannot be performed while the motor is
running
•
AMA can not be performed on a motor with a
bigger power rating than the frequency
converter, e.g. when a 5.5 kW motor is
connected to a 4 kW frequency converter.
NOTICE
Avoid generating external torque during AMA.

If one of the settings in parameter group 1-2* Motor
Data is changed, the advanced motor parameters,
1-30 Stator Resistance (Rs) to 1-39 Motor Poles, will return
to default setting.
NOTICE
Full AMA should be run without filter only while
reduced AMA should be run with filter.
