3.4 Auto Tune

Auto tune is a test procedure that measures the electrical
characteristics of the motor to optimize compatibility
between the adjustable frequency drive and the motor.
•
The adjustable frequency drive builds a
3 3
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 P-02, P-03, P-06, P-07, F-04 and F-05.
•
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 [2] Reduced Auto Tune
•
If warnings or alarms occur, see 9 Warnings and
Alarms
•
Run this procedure on a cold motor for best
results

3.5 Check Motor Rotation

Before running the adjustable frequency drive, check the
motor rotation. The motor will run briefly at 5 Hz or the
minimum frequency set in F-16 Motor Speed Low Limit [Hz].
1. Press [Main Menu] twice on the keypad.
2. Enter Parameter Data Set and scroll to P-## Motor
Data and press [OK] to enter.
3. Scroll to P-08 Motor Rotation Check.
4. Press [OK].
5. Scroll to [1] Enable.
The following text will appear: Note! Motor may run in
wrong direction.
6. Press [OK].
7. Follow the on-screen instructions.
To change the direction of rotation, remove power to the
adjustable frequency drive and wait for power to
discharge. Reverse the connection of any two of the three
motor cables on the motor or adjustable frequency drive
side of the connection.

3.6 Local Control Test

CAUTION
MOTOR START!
Ensure that the motor, system and any attached
equipment are ready for start. It is the responsibility of the
user to ensure safe operation under any condition. Failure
to ensure that the motor, system, and any attached
equipment are ready for start could result in personal
injury or equipment damage.
NOTE!
The [hand] key provides a local start command to the
adjustable frequency drive. The [Off] key provides the stop
function.
When operating in local mode, [
decrease the speed output of the adjustable frequency
drive. [◄] and [►] move the display cursor in the numeric
display.
