Cable shields are typically tied to frame/backplane ground. One end only if you want to avoid ground loops. The cable shield from your VFD to motor connection should also be tied to frame/backplane ground. I don't see a filter on the power feed to that GS2 VFD?Do you have one? The Automati

I've never been fond of the idea of removing the PC from its enclosure. I've always thought that the steel case (PC cases are always steel I think) shields the mother board from interference. The PCi or other plug in cards have no support without an enclosure and I have seen one that had been brok

One question I had when wiring up the system is I connected the west amp servo cable _shield_ to the backpanel. Which is also where the VFD is attached and pretty much everything else would be grounded to that as well. I was concerned about noise with that... Should I have attached that to 0Vdc.

So this is all off the same transformer? This is really not a problem as long as all of your power feeds are referenced to building ground. (wired to code) I would put a ground terminal/bus in the panel and make sure you tie all incoming ground wires to the same ground buss right in the box.
