4.5 Test Run
172 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
◆ Operating with the Load Connected
After performing a no-load test run as illustrated previously, connect the motor and
proceed to run the load.
■ Notes on Connected Machinery
• 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.
• Check the external emergency stop circuit. Check that other safety precautions
have been followed.
■ Checklist Before Operation
• 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. Refer to Motor Hunting and Oscillation Control
Parameters on page 191 and correct the problem if hunting or oscillation occurs or
if there are control-related problems.
■ Operating the Motor Loaded
Test run the application similarly to the no-load test procedure when connecting the
machinery to the motor. Refer to No-Load Operation on page 169.
◆ Verifying Parameter Settings and Backing Up Changes
Check changes to parameter settings as a result of Auto-Tuning using the Verify
function. Refer to Verifying Parameter Changes: Verify Menu on page 114.
Save the verified parameter settings. Change the access level or set a password to
the drive to prevent accidental modification of parameter settings.
