7.2.5 Configuring Automatic Energy Optimization
Automatic energy optimization (AEO) is a procedure that minimizes voltage to the motor, reducing energy consumption, heat, and
noise.
Procedure
Press [Main Menu].
Select
1–** Load and Motor
and press [OK].
Select
1–0* General Settings
and press [OK].
Select
parameter 1-03 Torque Characteristics
and press [OK].
Select either
[2] Auto Energy Optim CT
or
[3] Auto Energy Optim VT
and press [OK].
7.2.6 Configuring Automatic Motor Adaptation
Automatic motor adaptation (AMA) 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
.
N O T I C E
SOME MOTORS ARE UNABLE TO RUN THE COMPLETE VERSION OF THE TEST AND WILL TRIGGER AN ALARM.
In that case, or if an output filter is connected to the motor, select
[2] Enable reduced AMA
.
Procedure
Press [Main Menu].
Select
1–** Load and Motor
and press [OK].
Select
1–2* Motor Data
and press [OK].
Select
parameter 1-29 Automatic Motor Adaptation (AMA)
and press [OK].
Select
[1] Enable complete AMA
and press [OK].
Press [Hand On] and then [OK].
The test runs automatically and indicates when it is complete.
7.3 Testing Before System Start-up
7.3.1 Testing Motor Rotation
N O T I C E
INCORRECT MOTOR ROTATION
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.
Procedure
Press [Hand On].
Move the left cursor to the left of the decimal point by using the left arrow key.
Enter an RPM that slowly rotates the motor and press [OK].
The motor runs briefly at either 5 Hz or the minimum frequency set in
parameter 4-12 Motor Speed Low Limit [Hz]
.
If the motor rotation is wrong, set
parameter 1-06 Clockwise Direction
to
[1] Inverse
.
7.3.2 Testing Encoder Rotation
Use this procedure if encoder feedback is used. For more information on the encoder option, refer to the option manual.
Procedure
Select
[0] Open Loop
in
parameter 1-00 Configuration Mode
.
