For the best adaptation of the adjustable frequency drive, run the AMA on a cold motor.
AMA cannot be performed while the motor is spinning.
NOTE
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.
NOTE
Avoid generating external torque during AMA.
NOTE
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.
This parameter cannot be adjusted while the motor is running.
