is available).
2. Connect terminal 27 to terminal 12 or set
5-12 Terminal 27 Digital Input to [0] No function.
3. Activate the AMA 1-29 Automatic Motor
Adaptation (AMA).

sine-wave filter is mounted, run only the reduced
6 6
AMA, or remove the sine-wave filter during the
AMA procedure.
5. Press [OK]. The display shows Press [Hand on] to
start.

Unsuccessful AMA
1. The adjustable frequency drive enters alarm
mode. A description of the alarm can be found in
the Warnings and Alarms chapter in the product-

measuring sequence carried out by the AMA
before the adjustable frequency drive entered

description of the alarm assist in troubleshooting.
If contacting Danfoss for service, make sure to
mention number and alarm description.
NOTICE!
Unsuccessful AMA is often caused by incorrectly
registered motor nameplate data or a difference that is
too large between the motor power size and the
adjustable frequency drive power size.
