    Well, no such jerky rotation in any mode with Toshiba VFD.
    I guess it's not normal that spindle body (lying on a table) is twitching when accelerating from rest? I don't remember that with my previous Huangyang either.

    I should probably watch the VFD output with my O-scope...

    Hi Corwin, Bob Wilson, RayG and others,
    has anyone finally successfully repaired a Huanyang VFD?
    I'm still interested to find out all I can about these drives, mainly for future reference.
    Cheers,
    Joe

    Hi Joe I was going to try it, but the cost of the components put me off and the supplier sent me a new one under warranty anyway. I do still have all the parts though, so it may change at some time in the future.

    That was 6 years ago. I'd guess that the IGBTs are in the bin by now.
    Those were the droids I was looking for.
