NB!
Full AMA should be run without filter only while reduced AMA should be run with filter.

to run the motor optimally. The default settings are figures based on common motor parameter values from normal standard motors. If the motor
parameters are not set correctly, a malfunction of the frequency converter system may occur. If the motor data is not known, running an AMA (Automatic
Motor Adaptation) is recommended. See the

Iron Loss Resistance (Rfe)
Function:
Set the stator resistance value. Enter the value from a motor data sheet or perform an AMA on a
cold motor. This parameter cannot be adjusted while the motor is running.
Function:
Set the main reactance of the motor using one of these methods:
1. Run an AMA on a cold motor. The frequency converter will measure the value from the
motor.
2. Enter the X value manually. Obtain the value from the motor supplier.

3. Use the X default setting. The frequency converter establishes the setting on the basis of
