5.4.5 Automatic Energy Optimisation (AEO)

NOTICE
AEO is not relevant for PM motors.
Automatic Energy Optimisation (AEO) is recommended for
•
Automatic compensation for oversized motors
•
Automatic compensation for slow system load
change
•
Automatic compensation for seasonal changes
5 5
•
Automatic compensation for low motor loading
•
Reduced energy consumption
•
Reduced motor heating
•
Reduced motor noise
To activate AEO, set parameter 1-03 Torque Characteristics
to [2] Auto Energy Optim. CT or [3] Auto Energy Optim. VT.

5.4.6 Automatic Motor Adaptation (AMA)

NOTICE
AMA is not relevant for PM motors.
Automatic motor adaptation (AMA) is a procedure that
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 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 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].

5.5 Checking Motor Rotation

WARNING
MOTOR START
Failure to ensure that the motor, system, and any
attached equipment are ready for start can result in
personal injury or equipment damage. Before start,

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 4-12 Motor Speed Low Limit [Hz].

NOTICE
To change the direction of rotation, remove power to
the frequency converter and wait for power to discharge.
Reverse the connection of any 2 of the 3 motor wires on
the motor or frequency converter side of the connection.
