Another update, Automation Direct has an EMI input filter designed for that drive that mounts under it so that is on order as well as a ferrite bracelet... Peter said it was a bracelet not a bead. At least knowing it's the VFD and not an unknown issue is a big relief for me. In any case I have a well grounded machine now :)
