Operating With The Load Connected; Verifying Parameter Settings And Backing Up Changes - YASKAWA V1000 Series Technical Manual

4.7 Test Run
6.
The drive should operate normally. Press
complete stop.
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.
Note: 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.
Refer to Motor Hunting and Oscillation Control Parameters on page
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.

Verifying Parameter Settings and Backing Up Changes

u
Check changes to parameter settings as a result of Auto-Tuning using the Verify function.
64.
Save the verified parameter settings. Change the access level or set a password to the drive to prevent accidental modification of parameter settings.
Backing Up Parameter Values: o2-03
n
Performing the following procedure stores all parameters settings to drive memory where they can later be recalled if necessary. Set o2-03 to "1" to save
parameter changes. This saves all parameter settings, and then returns o2-03 to 0. The drive can now "recall" the saved parameters by performing a "user-
initialization" (A1-03 = 1110).

A1-03 Initialize Parameters
Parameter Access Level: A1-01
n
Setting the Access Level for "Operation only" (A1-01 = 0) allows the user to access parameters A1-oo and Uo-oo only. Other parameters are not
displayed.
Setting the Access Level for "User Parameters" (A1-01 = 1) allows the user to access parameters that have been previously saved as Preferred Parameters.
This is helpful when displaying only the relevant parameters for a specific application.
No. Parameter Name
Selects which parameters are accessible via the digital operator.
