Stagehand Apprentice

There are a lot of parameters - just 1 mis-set parameter can cause countless hours of troubleshooting chaos.

The Stagehand Apprentice does not include an external keypad to the Mitsubishi D700 series VFD. If you need to manually restore parameters, you'll need to open the top of the case to get to the keypad.

With the case open, confirm the stock parameters are set properly, making any adjustments based on the machine connected. If you've checked the parameters and are still stuck, it's time to start from scratch by resetting the VFD back to factory settings.

Once you have reset the VFD you'll need to manually input the Stock Parameters.
