Normally you would take the all of you shields to a single point in the cabinet and Gnd it. One end seems to be the way of thinking now for most things although my servo drives have both ends of the encoder cables connected. All other shielded wires just have one end connected.
Just to confirm, all is well when the VFD is not running the spindle?
Possibly some line filters on the VFD may help.
