Check that the VFD is connected to ground (earth) properly and also that it is only connected to ground in one place to avoid a ground loop. (Connecting to ground at the power inlet and again to the machine frame will cause a ground loop if the machine frame is also connected to ground - does this make sense ?)
VFD's usually wire up right first time but when it goes wrong they are a real bugger. (having a VHF music radio on in the shop helps detect if any RF noise is present and needs shielding).
