The control system detects the transition to axis mode automatically according to the program sequence. Explicit
programming of M70 in the part program is, therefore, essentially no longer necessary. However, M70 can continue to be
programmed, e.g to increase the legibility of the part program.

Example 1: Position spindle with negative direction of rotation
Spindle 1 is to be positioned at 250° with negative direction of rotation:
