Step 3. Activate the Automatic Motor Adaptation (AMA)
Performing an AMA will ensure optimum performance. The
AMA measures the values from the motor model
equivalent diagram.
1. Connect terminal 27 to terminal 12 or set
5-12 Terminal 27 Digital Input to 'No function'
( 5-12 Terminal 27 Digital Input [0])
2. Activate the AMA 1-29 Automatic Motor
Adaptation (AMA) .
3. Choose between complete or reduced AMA. If an
LC filter is mounted, run only the reduced AMA,
or remove the LC filter during the AMA
procedure.
4. Press the [OK] key. The display shows “Press
[Hand On] to start”.
5. Press the [Hand On] key. A progress bar indicates
if the AMA is in progress.
Stop the AMA during operation
1. Press the [OFF] key - the Adjustable frequency
drive enters into alarm mode and the display
shows that the AMA was terminated by the user.
Successful AMA
1. The display shows “Press [OK] to finish AMA”.
2. Press the [OK] key to exit the AMA state.
Unsuccessful AMA
1. The Adjustable frequency drive enters into alarm
mode. A description of the alarm can be found in
the
Troubleshooting section.
2. "Report Value” in the [Alarm Log] shows the last
measuring sequence carried out by the AMA
before the Adjustable frequency drive entered
alarm mode. This number along with the
description of the alarm will assist you in trouble-
shooting. If you contact Danfoss Service, make
sure to mention number and alarm description.
Unsuccessful AMA is often caused by incorrectly registered
motor nameplate data or a difference between the motor
power size and the Adjustable frequency drive power size
that is to great.
