    Indexer/Lathe

    Hi to all of you
    I have a stepper motor KL34H280-45-8A 640 oz In. 1.8° /200 Steps Per Rev.
    NEMA 34 Framewith, Gecko driver G203V with a 10/1 ratio gearbox that is limited to 4000 RPM at the intake and I would like to know the fastest velocity I can input in Mach3 to avoid to override the max gearbox RPM.
    This doesn't mean that I will be using the max RPM but rather to stay on the safe side
    Thank you

    You'll probably never be able to get that motor to spin faster than 1200-1300 rpm.

    Hi Gerry
    So if I understand this correctly with this motor, there is no chance to override the gearbox max input RPM.
    To get the motor to 1200+- RPM there must be a formula to calculate the velocity to input in Mach3.
    Thank you

    I think velocity on a rotary axis is degrees/min, but I'm not positive??
    If it is, then 1200*360/10, I think. 43200?
