Step 3. Activate Automatic Motor Adaptation (AMA)
Performing AMA ensures best possible performance. AMA automatically takes measurements from the specific motor connected and compensates for
installation variances.

Connect terminal 27 to terminal 12 or use [MAIN MENU] and set Terminal 27 par. 5-12 to
No operation
(par. 5-12 [0])
2.
Press [QUICK MENU], select "Q2 Quick Setup", scroll down to AMA par. 1-29.
3.
Press [OK] to activate the AMA par. 1-29.

Choose between complete or reduced AMA. If sine wave filter is mounted, run only reduced AMA, or remove sine wave filter during AMA
procedure.
5.
Press [OK] key. Display should show “Press [Hand on] to start”.

Unsuccessful AMA
1.
The frequency converter 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 frequency converter entered alarm
mode. This number along with the description of the alarm will assist troubleshooting. If contacting Danfoss Service, make sure to mention
number and alarm description.
NB!
Unsuccessful AMA is often caused by incorrectly entered motor name plate data or too big difference between the motor power size
and the frequency converter power size.
