I would think the problem can be traced to the particular VFD. I recently had a small VFD on a saw conveyor, newly installed that would trip a high voltage fault due to our ungrounded 440 delta system. The solution was to isolate the drive the drive chassis from ground. We had measured 35 volts to ground from the drive case. This type of leakage current could easily cause the GFCI to trip.
