Tom,
Hard to tell from the picture but I would make sure that ground is
properly connected in star configuration, i.e. there is only one
ground point [1] in the cabinet and the CNC machine. I suspect you get
some ground currents somewhere which possibly cause enough noise to mess
up your VFD.
Either move the VFD to its own enclosure or isolate it with sheet metal
and metal screening, grounded to the enclosure. That will block RFI/EMI
radiating directly from the VFD.

Thanks for all the info Bruce! I suspect you are right that it is radiated
noise. I should probably start with the outbound motor wire from the VFD. It
is about 5 ft. long and not shielded. There are also a couple other cables I
can shield as well that current aren’t.

Replacing the unshielded spindle motor cable with a shielded cable and
grounding the shield in the electrical panel is probably going to yield
the maximum bang for the buck.

I have had to tweak the deadband value to get rid of loop instability
due to worn ball screws.
Noise and mechanical slop would cause the loop to hunt badly without
