# Stagehand Parameters

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.

### Before resetting any parameters, make sure your drive is not displaying a brake fault.

{% endhint %}

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:

1. Press the <img src="/files/FI9N6dzdvwtuvR2NLZP9" alt="" data-size="line"> button on the VFD keypad until **P.0 is displayed**
2. Use the <img src="/files/MZokUilNr1fjOVggGO8Z" alt="" data-size="line"> wheel on the keypad until **P.414** is displayed
3. Press <img src="/files/s66RX9Iw4yufYE3GZyXA" alt="" data-size="line">. 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**
4. **If '0' is displayed**, use the <img src="/files/MZokUilNr1fjOVggGO8Z" alt="" data-size="line"> wheel to set the proper value
5. Press <img src="/files/s66RX9Iw4yufYE3GZyXA" alt="" data-size="line"> to confirm the new value.
   * The display will flash between P.414 and the value you set
6. **Power cycle the VFD** for at least **5 seconds**
   * Engage the E-Stop or remove the Input Power

{% hint style="success" %}
**Once reset try jogging the motor.**

If all functions as expected you are ready to Make It Move!
