Hi, we are having a Doosan DNM 540 Milling machine with a Fanuc control. The machine does have a built in (hidden ) program (MO2)for spindle warm up in the morning. We would like to make some alteration in the way the spindle is running, making it to rotate for 2min clockwise and 2min anticlockwise, thus saving some times.

Now to achieve this we neeed to change a certain parameter where the new program will be store in order to replace the # O2 program.

What will be that parameter?

Thanks in advance.
