Step 3. Activate Automatic Motor Adaptation (AMA)
Performing an AMA ensures best possible performance. An AMA automatically takes measurements from the specific motor connected and compensates
for installation variances.
1.
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 Set-up", scroll down to AMA par. 1-29.
3.
Press [OK] to activate the AMA par. 1-29.
4.
Choose between complete or reduced AMA. If the sine wave filter is mounted, run only reduced AMA, or remove the sine wave filter during the
AMA procedure.
5.
Press the [OK] key. The display should show “Press [Hand on] to start.”
6.
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 in troubleshooting. If contacting Danfoss Service, make sure to
mention the number and alarm description.
NOTE!
An unsuccessful AMA is often caused by incorrectly entered motor nameplate data or too big of a difference between the motor and
the adjustable frequency drive power sizes.
