    Default 828d "Unwind" rotary axis

    Hi,
    I have a sinumerik 828d control on a VMC (XYZ710). I am having trouble finding a way to return the 4th axis (MA1) to zero quicky after certain programmes require the axis to rotate 30+ times in one direction.

    At the moment I am having to "unwind" the axis. Adjusting the modulo parameter isn't an option as it will upset previous programmes we have generated.
    Haas use G28 to return to zero quickly although even from reading elsewhere saying G28 is functional with the Sinumerik control; it does not work.
    Page 33-34 explains here for the 828d control

    Could someone help in either letting me know that it does/not have the option to do similar, or whether I have to change a parameter to get it to work? G28 is not recognised by the machine for some reason.

    Regards

    Colin
