3.4 Auto Tune

Auto tune is a test procedure that measures the electrical
characteristics of the motor to optimize compatibility
between the drive and the motor.
•
The drive builds a mathematical model of the
motor for regulating output motor current. The
3 3
procedure also tests the input phase balance of
electrical power. It compares the motor character-
istics with the data entered in parameters P-0#.
•
It does not cause the motor to run or harm to
the motor
•
Some motors may be unable to run the complete
version of the test. In that case, select Reduced
Auto Tune
•
If an output filter is connected to the motor,
select Reduced Auto Tune
•
If warnings or alarms occur, see 8 Warnings and
Alarms
•
Run this procedure on a cold motor for best
results

3.5 Check Motor Rotation

Prior to running the frequency converter, check the motor
rotation.
1. Press [Hand].
2. Press [►] for positive speed reference.
3. Check that the speed displayed is positive.
When H-48 Clockwise Direction is set to [0]* Normal (default
clockwise):
4a. Verify that the motor turns clockwise.
5a. Verify that the Keypad direction arrow is
clockwise.
When H-48 Clockwise Direction is set to [1] Inverse (counter-
clockwise):
4b. Verify that the motor turns counter-clockwise.
5b. Verify that the Keypad direction arrow is
counter-clockwise.

3.6 Local-control Test

CAUTION
MOTOR START!
Ensure that the motor, system, and any attached
equipment is ready for start. It is the responsibility of the
user to ensure safe operation under any operational
condition. Failure to ensure that the motor, system, and
any attached equipment is ready for start could result in
personal injury or equipment damage.
NOTE
The Hand key on the Keypad provides a local start
command to the drive. The OFF key provides the stop
function.
When operating in local mode, the up and down arrows
on the Keypad increase and decrease the speed output of
the drive. The left and right arrow keys move the display
cursor in the numeric display.

Press [Hand].
Accelerate the drive by pressing [
Moving the cursor left of the decimal point
provides quicker input changes.
Note any acceleration problems.
Press [OFF].
Note any deceleration problems.
