Example of a PLC-program for spindle-orientation with M19/M20
Program description:
Using the M-Function M19 to activate a spindle-orientation to the value which is determined by the
spindle-orientation cycle.
Using the M-Function M20 to activate a spindle-orientation to the value which is stored in
MP4210.47.
