Why Would You Restore Parameters?
There are times when you find yourself in the weeds with a misbehaving Stagehand and nothing you do seems to make a difference. For me, these times generally coincide with adjusting parameters, running an auto-tune or (of course) 1st tech/1st dress/1st preview. VFDs are complicated devices and one wrong parameter can wreak havoc - tossing out errors, not triggering the brakes or just not working at all.
Most often fixing a parameter issue is as simple as clicking a few buttons in Spikemark. If you're stuck with a drive fault or some other weird errors, click on the Stagehand you have below to find out how to restore the VFD to factory settings.
If BRAKE FAULT is displayed on your Stagehand Card, follow these steps to clear your brake fault before clearing/restoring your Stagehand parameters:
The most likely cause of BRAKE FAULT being displayed is that the PLC program was not reinstated after the auto-tune. Let’s confirm the value in parameter 414:
Press the button on the VFD keypad until P.0 is displayed
Use the wheel on the keypad until P.414 is displayed
Press . The screen will display the current value setting.
0 = PLC program is not running
1 = PLC program for an A700
2 = PLC program for an A800
If '0' is displayed, use the wheel to set the proper value
Press to confirm the new value.
The display will flash between P.414 and the value you set
Power cycle the VFD for at least 5 seconds
Engage the E-Stop or remove the Input Power
Once reset try jogging the motor.
If all functions as expected you are ready to Make It Move!
