• Make sure that the motor accelerates and decelerates smoothly.

Do an Actual-Load Test Run

Before a test run, make sure that U1-03 [Output Current] is not too high.
Connect the motor and machine, then do the test run with the same procedure that you used for the no-load test
run.
1.
Energize the drive, or push
2.
Use

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.
Ex.: 6 Hz → 20 Hz → 30 Hz → 40 Hz → 50 Hz → 60 Hz
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.
8.
Make sure that the motor rotates correctly, then push
The RUN LED flashes and goes off when the motor stops completely.
9.
Change the frequency reference and direction of motor rotation, and make sure that there are no unusual
sounds or vibrations.
10.
If the control function causes hunting or oscillation errors, adjust the settings to stop the errors.
