Step 3. Activate the Automatic Motor Adaptation (AMA).
Performing an AMA ensures optimum performance. The
AMA measures the values from the motor model
equivalent diagram.
1. Connect terminal 37 to terminal 12 (if terminal 37
is available).
2. Connect terminal 27 to terminal 12 or set
parameter 5-12 Terminal 27 Digital Input to [0] No
function.
3. Activate the AMA parameter 1-29 Automatic Motor
Adaptation (AMA).
4. Select between complete or reduced AMA. If a
sine-wave filter is mounted, run only the reduced
AMA, or remove the sine-wave filter during the
AMA procedure.
5. Press [OK]. The display shows Press [Hand On] to
start.
6. Press [Hand On]. A progress bar indicates if the
AMA is in progress.
Stop the AMA during operation
1. Press [Off]. The adjustable frequency drive enters
into alarm mode and the display shows that the
user terminated the AMA.
Successful AMA
1. The display shows Press [OK] to finish AMA.
2. Press [OK] 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 .
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 helps with trouble-
shooting. State the alarm number and description
when contacting Danfoss service.
NOTICE!
Incorrectly registered motor nameplate data, or a
difference between the motor power size and the
adjustable frequency drive power size that is too large
often causes unsuccessful AMA.
Step 4. Set the speed limit and ramp time.
