8. Select language and press [OK]. Then enter the
motor data in parameters 1-20/1-21 through 1-25.
The information can be found on the motor
nameplate.
9. A jumper wire should be in place between control
terminals 12 and 27. If this is the case, leave
5-12 Terminal 27 Digital Input at factory default.
Otherwise select No Operation. For frequency
converters with an optional Danfoss bypass, no
jumper wire is required.

3.4 Automatic Motor Adaptation

Automatic motor adaptation (AMA) is a test procedure that
measures the electrical characteristics of the motor to
optimize compatibility between the frequency converter and
the motor.
•
The frequency converter builds a mathematical
model of the motor for regulating output motor
current. The procedure also tests the input phase
balance of electrical power. It compares the motor
characteristics with the data entered in parameters
1-20 to 1-25.
•
It does not cause the motor to run or harm to the
motor
•
Some motors may be unable to run the complete
version of the test. In that case, select Enable
reduced AMA
•
If an output filter is connected to the motor, select
Enable reduced AMA
•
If warnings or alarms occur, see 8 Warnings and
Alarms
•
Run this procedure on a cold motor for best results
To run AMA
1. Press [Main Menu] to access parameters.
2. Scroll to parameter group 1-** Load and Motor.
3. Press [OK].
4. Scroll to parameter group 1-2* Motor Data.
5. Press [OK].
6. Scroll to 1-29 Automatic Motor Adaptation (AMA).
7. Press [OK].
8. Select Enable complete AMA.
9. Press [OK].
10. Follow on-screen instructions.
11. The test will run automatically and indicate when it
is complete.
