Operating Guide

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
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 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.
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
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.

7.3 Testing Before System Start-up

7.3.1 Testing Motor Rotation

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
1. Press [Hand On].
2.
Move the left cursor to the left of the decimal point by using the left arrow key.
3. 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].
4.
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
1.
Select [0] Open Loop in parameter 1-00 Configuration Mode.
2.
Select [1] 24 V encoder in parameter 7-00 Speed PID Feedback Source.
3. Press [Hand On].
