u No-Load Operation Test Run
This section explains how to operate the drive with the motor decoupled from the load during a test run.
n Before Starting the Motor
Check the following items before operation:
• Ensure the area around the motor is safe.
• Ensure external emergency stop circuitry is working properly and other safety precautions have been taken.
n During Operation
Check the following items during operation:
• The motor should rotate smoothly (i.e., no abnormal noise or oscillation).
• The motor should accelerate and decelerate smoothly.
u Test Run with the Load Connected
After performing a no-load test run, connect the motor and proceed to run the motor and load together.
n Checklist Before Operation
• The motor should rotate in the proper direction.
• The motor should accelerate and decelerate smoothly.
n Operating the Motor under Loaded Conditions
Test run the application similarly to the no-load test procedure when connecting the machinery to the motor.
• Monitor U1-03 for overcurrent during operation.
• If the application permits running the load in the reverse direction, change the motor direction and the frequency reference
while watching for abnormal motor oscillation or vibration.
• Correct any problems that occur with hunting, oscillation, and other control-related issues.
u Test Run Checklist
