    Mike,

    I've taken your advice and played with the settings a little. I've got it to behave normalish. It seems quite slow and sluggish and it still jerks in the opposite direction after making a...

    OK but take the motor and spindle out of the picture. How about just the gearbox itself?

    My motor is good for 7500 and the spindle is presumably good for 10-12k.

    Damn... I was afraid that I couldnt run the 15hp on a smaller rated VFD. It's not that I need 15hp, it's just that I have that spindle for free:) It's from our work machines that each run 2 of...
