    Hi Gerry
    Do you mean via an externally generated voltage, or from a voltage provided by the VFD? I'm using the 10V internal voltage via a manually set pot and has been ok for a few years.
    Maybe your pot is a bit scratchy and the signal you measure with meter is smoothed out but the VFD is seeing the rapid fluctuations?
    If it is an external supply then maybe wire up a pot direct to see if that is steady?
    Edit
    Sorry just noticed you tube link. Will view video first !
