    Default Home position problem in CNC turning Center

    Dear All,

    I need your help regarding our machine. We have COLCHESTER 2000L CNC Turning Center, Controller FANUC OT. The problem is, when we give the command for home position its x axis reaches its home position but z axis does not. I have disengage the belt of z axis from its motor and when the command for home position is given its z axis motor keeps on running and don't stop or engage at some point.

    Kindly help me in this situation. Thank you.

    There are no zero return switches or overtravel switches
    Over travels are set up in the soft limit parameters

    You need to reset your origin positions
    par 22 bit 0= x bit 1=z

    set parameter to 0 on required axis
    move with hand wheel to correct zero position( look in your manual, gives dimensions to ref point from chuck face/ chuck centreline position)
    BE CAREFUL NOT TO TRAVEL TO FAR AS YOU WILL HIT THE END OF TRAVEL AND CAUSE DAMAGE
    Set parameter 22 to 1 on the axis you are setting up
    switch off and back on
