Coupled motion combination

Default value: All bits 0

The definition of this coupled axis combination defines which coupled axis pairings form a

coupled axis combination and how the coupled motion is performed (coupled motion in the

same direction or opposite directions).

The 9 possible coupled axis combinations are programmed with G151 to G159. Each coupled

axis combination is defined with 3 NC MDs corresponding to the 9 coupled axis pairings (12

times 2 bits).

Active: RESET
