After mounting controller in electrical panel on original setup and having issues with screen going black I decided to move controller out of panel and away from VFD. With all the new updates for mouse and USB ports a redesign of screen mount stand was in order.
No the VFD was in the cabinet with the controller. So I moved controller out of the electrical cabinet and directly under screen in the new encloser. Now there are no issues with noise from VFD. I have 25 of cord so I can move pedestal on wheels to were I need it. But before I moved controller it didn t matter how far the screen was from VFD. I tried everything to shield controller but it didn t help.
