information is located on the motor name plate data.
Step 2. Enter the motor name plate data in this parameter
list.
To access this list first press the [QUICK MENU] key then
select "Q2 Quick Setup".

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 frequency converter
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 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 you in troubleshooting. If you
contact Danfoss Service, make sure to mention
number and alarm description.
Unsuccessful AMA is often caused by incorrectly registered
motor name plate data or too big difference between the
motor power size and the frequency converter power size.
Step 4. Set speed limit and ramp time
Set up the desired limits for speed and ramp time.
