Automatic Motor Adaptation (Ama); Checking Motor Rotation; Local-Control Test; System Start-Up - Danfoss VLT Refrigeration Drive FC 103 Operating Instructions Manual

Commissioning
To activate AEO, set parameter 1-03 Torque Characteristics to
[2] Auto Energy Optim. CT or [3] Auto Energy Optim. VT.

5.4.7 Automatic Motor Adaptation (AMA)

AMA is a procedure which optimises 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 entered nameplate
data.
•
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 [2] Enable reduced AMA.
•
If warnings or alarms occur, see
chapter 7 Diagnostics and Troubleshooting.
•
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].
Scroll to parameter group 1-2* Motor Data and
3.
press [OK].
4. Scroll to parameter 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 indicates when it
is complete.
8. The advanced motor data is entered in parameter
group 1-3* Adv. Motor Data.

5.5 Checking Motor Rotation

NOTICE
Risk of damage to pumps/compressors caused by motor
running in wrong direction. Before running the
frequency converter, check the motor rotation.
The motor runs briefly at 5 Hz or the minimum frequency
set in parameter 4-12 Motor Speed Low Limit [Hz].
