increments verifying smooth operation results at all speeds. For each frequency monitor the drive output current
(U1-03) through the LED operator to confirm the current is well below the motor rated current. Example: 6 Hz →
50 Hz/60 Hz.

Note: To operate the drive, run (forward/reverse) command and frequency (or multi-step speed) reference are needed. Input these commands and references to the drive.

Operating with the Load Connected

u
After performing a no-load test run, connect the motor and proceed to run the load.
Notes on Connected Machinery
n
• Clear the area around the motor.
• The motor should come to a complete stop without problems. Connect the machinery.
• Fasten all installation screws properly. Check that the motor and connected machinery are held in place.
• Confirm that the Fast-stop circuit or mechanical safety operate correctly.
• Prepare to press the STOP button in the case of an emergency.
Checklist Before Operation
n
• The motor should rotate in the proper direction.
• The motor should accelerate and decelerate smoothly.
• Check U1-03 to ensure there is not overcurrent.
If the application permits running the load in the reverse direction, try changing motor direction and the frequency reference and watch for abnormal
motor oscillation or vibration. Correct the problem if hunting or oscillation occurs or if there are control-related problems.
Operating the Motor under Loaded Conditions
n
Test run the application similarly to the no-load test procedure when connecting the machinery to the motor.
