Classic+ Parameters
The Stagehand AC (AKA: The Classic) didn't require many parameter changes from the Mitsubishi factory stock. The Classic+ requires a few additional parameters to leverage the new features.
If after setting the following parameters and you are still having trouble, it's probably a good time to reset the VFD back to factory settings and start fresh.
Set Parameter 77 = 2 before jumping into manually entering parameters!
Check out the Parameters for an A800 or A700 Classic+ below.
