Notes on Connected Machinery
• Clear the area around the motor.
• The motor should come to a complete stop without problems.
• Connect the load and machinery to the motor.
• 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 measures operate correctly.
• Be ready to press the STOP button in case of emergency.

Checklist Before Operation
• The motor should rotate in the proper direction.
• The motor should accelerate and decelerate smoothly.

Operating the Motor under Loaded Conditions
Test run the application similarly to the no-load test procedure when connecting the machinery to the motor.
• Watch monitor parameter U1-03 during operation to ensure there is no overcurrent.
• If the application permits running the load in the reverse direction, try changing motor direction and the frequency
reference while watching for abnormal motor oscillation or vibration.
• Correct any problems that occur with hunting, oscillation, or other control-related issues.
