Do an Actual-Load Test Run

Connect the motor and machine, then do the test run with the same procedure you used for the no-load test run.
• Make sure that U1-03 [Output Current] is not too high.
1.
Energize the drive, or push
If [Home] is not shown on
2.
Set d1-01 [Reference 1] to 6.00 Hz.
3.
Push to illuminate the LOCAL/REMOTE indicator.
4.
Push .
The RUN indicator illuminates, and the motor runs at 6.00 Hz in the forward direction.
5.
Make sure that the motor is rotating in the correct direction and that the drive does not show a fault.
If the drive detects a fault, remove the cause.
6.
Push to increase the frequency reference value.
Change the setting value in increments of 10 Hz if necessary and examine the response.
7.
Each time you increase the setting value, use U1-03 [Output Current] to check the drive output current.
When the output current of the drive is not more than the motor rated current, the status is correct.
Ex.: 6 Hz → 20 Hz → 30 Hz → 40 Hz → 50 Hz → 60 Hz
8.
Make sure that the motor rotates correctly, then push
The RUN indicator will flash. When the motor stops, the indicator will go out.
9.
Change the frequency reference and direction of motor rotation, and make sure that there are no unusual
sounds or vibrations.
10.
If there are hunting or oscillation errors caused by control function, adjust the settings to stop the errors.
