6.3.5 Configuring Automatic Motor Adaptation
Context:
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.
NOTICE
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.
6.4 Testing Before System Start Up
Context:
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,
-
Ensure that equipment is safe to operate under any condition.
-
Ensure that the motor, system, and any attached equipment are ready for start.
6.4.1 Testing Motor Rotation
Context:
NOTICE
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.
