Enable reduced AMA Performs a reduced AMA of the stator resistance R
tem only.
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.
NB!
It is important to set motor par. 1-2* Motor Data correctly, since these form part of
the AMA algorithm. An AMA must be performed to achieve optimum dynamic motor
performance. It may take up to 10 min, depending on the power rating of the motor.
NB!
Avoid generating external torque during AMA.
NB!
If one of the settings in par. 1-2* Motor Data is changed, par. 1-30 to 1-39, the
advanced motor parameters, will return to default setting.
