VLT ® Automation Drive FC 300
Instruction Manual High Power
1-29 Automatic Motor Adaptation (AMA)
Option:
[0] * OFF
[1] Enable complete AMA
[2] Enable reduced AMA
Note:
• For the best adaptation of the adjustable frequency drive, run the AMA on a cold motor.
• AMA cannot be performed while the motor is running.
• AMA cannot be performed on permanent magnet motors.
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.

Function:
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced
motor parameters (par. 1-30 to par. 1-35) during motor standstill.
Activate the AMA function by pressing [Hand on] after selecting [1] or [2]. See also the section
Automatic Motor Adaptation . After a normal sequence, the display will read: "Press [OK] to finish
AMA". After pressing the [OK] key, the adjustable frequency drive is ready for operation.
This parameter cannot be adjusted while the motor is running.
