    This is for Vector Speed mode only.

    I've been having problems myself with a different drive and spindle but this is partly how it was solved.

    My spindle motor plate said;

    V=220
    A=9.5
    Speed=24000
    Freq.=400
    kW=2.2

    So that's what I put in the VFD, however I was advised to change the VFD parameters to this by the manufacturers and it worked;

    V=110
    A=9.5
    Speed=12000
    Freq.=200
    kw=1.1

    It's to do with field weakening.
    Also it would only work with the VFD switching frequency set to 16kHz
    Make sure accel and decel are not less than 5 seconds, mine liked 10 seconds best, now run the auto tune.
