    Hurco spindle limitations

    Hello to everyone,

    Our company has bought a Hurco CNC, but we have one problem.
    The machine can not accept more than 2000rpm from the nc program, it means that if we put 2001 rpm in the program the machine won't start.
    If we start the machine with 2000 rpm we can increase the rpm until 2600 because of the control panel (130%).
    Are there any limitations parameters?

    Can anyone help, Thanks

    Ah. It may be the winding select contactor for the spindle drive. Look for a black contactor in the cabinet that is connected to the spindle drive outputs. I think they are marked FV-75A. Check to see if that switches over and if not, see if you get an error message on the drive.
