Control Schematic Advice

[Clive S]

It seems like a few amendments are needed.
Has anyone got an easy to understand grounding/earthing diagram for a similar circuit, and info regarding suitable components to use?
Below is a very basic sketch I've found but not enough detail.

Just my 2 cents worth. Personally I would not put the VFD inside the control box as it will generate a lot of noise (rf speaking). Also it's not a good idea to daisy chain the power supply to the drives, I would run separate cables back from each drive to the power supply. The grounding of all the screens on the cy cables etc should all go back to one central place, (called a star) Most people tend to ground the screen at one end only.. ..Clive

Hi Clive, thanks for your comments.
I was only using the sketch to show a very simple example of grounding/earthing and was hoping to get feed back relating to methods and components used.
