5.4.5 Automatic Motor Adaptation (AMA)

NOTICE!
AMA is not relevant for permanent magnet motors.
Automatic motor adaptation (AMA) is a procedure that
optimizes compatibility between the adjustable frequency
drive and the motor.
•
The adjustable frequency drive 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
•
The motor shaft does not turn and no harm is
done to the motor while running the AMA.
•
Some motors may be unable to run the complete
version of the test. In that case, select [2] Enable
reduced AMA.
•
If an output filter is connected to the motor,
select Enable reduced AMA.
•
If warnings or alarms occur, see chapter 7.4 List of
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
and press [OK].
3. Scroll to parameter group 1-2* Motor Data and
press [OK].
4. Scroll to 1-29 Automatic Motor Adaptation (AMA)
and press [OK].
5. Select [1] Enable complete AMA and press [OK].
6. Follow the on-screen instructions.
7. The test runs automatically and indicate when it
is complete.

5.5 Checking Motor Rotation

Before running the adjustable frequency drive, check the
motor rotation.
When 1-06 Clockwise Direction is set to [0] Normal (default
clockwise):
When 1-06 Clockwise Direction is set to [1] Inverse (counter-
clockwise):

5.6 Checking Encoder Rotation

NOTICE!
When using an encoder option, refer to the option
manual.
Check encoder rotation only if encoder feedback is used.
Check encoder rotation in default open-loop control.

1. Press [Hand On].
2. Press [►] for positive speed reference.
3. Check that the speed displayed is positive.
4a. Verify that the motor turns clockwise.
5a. Verify that the LCP direction arrow is
clockwise.
4b. Verify that the motor turns counter-clockwise.
5b. Verify that the LCP direction arrow is counter-
clockwise.
Verify that the encoder connection is according
to Figure 5.5:
