Perform An Actual-Load Test Run - YASKAWA GA700 Technical Manual

3.9 Test Run
• Confirm that the motor is completely stopped.
• Connect the motor with the machinery.
Confirm that none of the mounting screws are loose, and that the load shaft of the motor is securely joined with
the machine coupling.
• As a precautionary safety measure in case of abnormal operation, make sure
can be pressed immediately.
■
Items to Check before Operation
• Check to make sure the direction of the machine's operation is correct (whether or not the motor will rotate in
the correct direction).
• Does the motor accelerate/decelerate smoothly?
◆

Perform an Actual-Load Test Run

Once the motor and machinery have been connected, a test run should be carried out in accord with the same
procedure that was used when performing a no-load test run.
• Confirm that U1-03 [Output Current] is not excessive.
1.
Energize the drive, or press
If [Home] is not displayed for
2.
Set d1-01 [Reference 1] to 6.00 Hz.
3.
Press so the LOCAL/REMOTE indicator is lit.
4.
Press .
The RUN indicator lights, and the motor runs at 6.00 Hz in the forward direction.
5.
Confirm that the motor is rotating in the correct direction and that there are no faults indicated by the drive.
If any faults were detected, eliminate their cause.
6.
Raise the frequency reference value by pressing
Change the setting value in increments of 10 Hz if needed while evaluating the response.
7.
Check the drive's output current using U1-03 [Output Current] each time the setting value is raised.
The status is normal if the output current of the drive does not exceed the motor rated current.
Ex.: 6 Hz → 20 Hz → 30 Hz → 40 Hz → 50 Hz → 60 Hz
8.
After confirming that the motor rotates normally, press
The RUN indicator will be flashing. Then, when the motor is completely stopped, it will go out.
9.
Change the frequency reference and direction of motor rotation, and check to see if there are any
abnormal sounds or vibrations.
10.
If errors such as hunting or oscillation attributable to control functionality occur, adjust accordingly.
