3.4 Automatic Motor Adaptation

Automatic motor adaptation (AMA) is a test procedure that
measures the electrical characteristics of the motor to
3 3
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 [2] 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
NOTE
The AMA algorithm does not work when using PM motors.
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 [1] Enable complete AMA.
9. Press [OK].
10. Follow on-screen instructions.
11. The test will run automatically and indicate when
it is complete.

3.5 Check Motor Rotation

Before running the frequency converter, check the motor
rotation. The motor will run briefly at 5 Hz or the
minimum frequency set in 4-12 Motor Speed Low Limit [Hz].

To change the direction of rotation, remove power to the
frequency converter and wait for power to discharge.
Reverse the connection of any two of the three motor
cables on the motor or frequency converter side of the
connection.

3.6 Local-control Test

CAUTION
MOTOR START!
Ensure that the motor, system and any attached
equipment are ready for start. It is the responsibility of the
user to ensure safe operation under any condition. Failure
to ensure that the motor, system, and any attached
equipment is ready for start could result in personal injury
or equipment damage.
NOTE
The [Hand On] key provides a local start command to the
frequency converter. The [Off] key provides the stop
function.
When operating in local mode, [ ] and [ ] increase and
decrease the speed output of the frequency converter. [ ]
and [ ] move the display cursor in the numeric display.
