6.4.3 Configuring Automatic Energy
Optimization
Automatic energy optimization (AEO) is a procedure that
minimizes voltage to the motor, reducing energy
consumption, heat, and noise.
1. Press [Main Menu].
2. Select 1-** Load and Motor and press [OK].
3. Select 1-0* General Settings and press [OK].
4. Select parameter 1-03 Torque Characteristics and
press [OK].
5. Select either [2] Auto Energy Optim CT or [3] Auto
6 6
Energy Optim VT and press [OK].
6.4.4 Configuring Automatic Motor
Adaptation
Automatic motor adaptation is a procedure that optimizes
compatibility between the drive and the motor.
The 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.
NOTICE
If warnings or alarms occur, see chapter 8.5 List of
Warnings and Alarms. Some motors are unable to run the
complete version of the test. In that case, or if an output
filter is connected to the motor, select [2] Enable reduced
AMA.
Run this procedure on a cold motor for best results.
1. Press [Main Menu].
2. Select 1-** Load and Motor and press [OK].
3. Select 1-2* Motor Data and press [OK].
4. Select parameter 1-29 Automatic Motor Adaptation
(AMA) and press [OK].
5. Select [1] Enable complete AMA and press [OK].
6. Press [Hand On] and then [OK].
The test runs automatically and indicates when it
is complete.

6.5 Testing Before System Start-up

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,

6.5.1 Motor Rotation
NOTICE
If the motor runs in the wrong direction, it can damage
equipment. Before running the unit, check the motor
rotation by briefly running the motor. The motor runs
briefly at either 5 Hz or the minimum frequency set in
parameter 4-12 Motor Speed Low Limit [Hz].

WARNING
Ensure that equipment is safe to operate under
any condition.
Ensure that the motor, system, and any
attached equipment are ready for start.
Press [Hand On].
Move the left cursor to the left of the decimal
point by using the left arrow key, and enter an
RPM that slowly rotates the motor.
Press [OK].
If the motor rotation is wrong, set
parameter 1-06 Clockwise Direction to [1] Inverse.
Select [0] Open Loop in parameter 1-00 Configu-
ration Mode.
Select [1] 24 V encoder in parameter 7-00 Speed
PID Feedback Source.
Press [Hand On].
Press [►] for positive speed reference
(parameter 1-06 Clockwise Direction at [0] Normal).
In parameter 16-57 Feedback [RPM], check that the
feedback is positive.
