    Lightbulb Milling spindle speed override on Mori Seiki mill-turn machine with Fanuc 31i A5

    Hello everyone. I'm new here and I need help.

    I am using Focas library to commnuicate with Mori Seiki NT3150 DCG mill-trun machine with Fanuc 31i A5.
    I want to write the override value for milling spindle. I found that I can use pmc_wrpmcrng(hanlde, 0, 0, 30, 30, &spindleOV) to change the spindle speed override value because it is store on variable G30.

    However, it defaultly changes the override for turning spindle.

    How can I change the override for milling spindle?

    Thanks,
    Hunter

    Is the machine running 2 paths?
    Is the turning spindle on the first path, and the milling spindle on the 2nd path?

    G30 is not a "variable" it is a byte of binary signals, and
