Activate the AMA function by pressing [Hand on] after selecting [1] or [2]. See also the section
Automatic Motor Adaptation
AMA". After pressing the [OK] key the frequency converter is ready for operation.

Function:
[0 - 60,000 RPM] Enter the minimum limit for motor speed. The Motor Speed Low
* Limit can be set to correspond to the manufacturer's recom-
mended minimum motor speed. The Motor Speed Low Limit
must not exceed the setting in par. 4-13
[RPM]
Function:
[0 - 60,000 RPM] Enter the maximum limit for motor speed. The Motor Speed
* High Limit can be set to correspond to the manufacturer's max-
imum rated motor speed. The Motor Speed High Limit must
exceed the setting in par. 4-11
Only par. 4-11 or 4-12 will be displayed depending on other pa-
rameters set in the Main Menu and depending on default set-
tings dependant on global geographical location.
NB!
The output frequency value of the frequency converter must not exceed a value
higher than 1/10 of the switching frequency.
Function:
The AMA function optimizes dynamic motor performance by au-
tomatically optimizing the advanced motor parameters (par.
1-30 to par. 1-35) while the motor is stationary.
OFF No function
Enable complete AMA performs AMA of the stator resistance R
R
X
Enable reduced AMA performs a reduced AMA of the stator resistance R
tem only. Select this option if an LC filter is used between the
frequency converter and the motor.
. After a normal sequence, the display will read: "Press [OK] to finish
For the best adaptation of the frequency converter, run AMA on a cold motor.
AMA cannot be performed while the motor is spinning.
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.
