M3: Coupled axes
5.6 Dynamic response of following axis
Master value coupling
Axis 4 is coupled to X via a master value coupling. The acceleration capability of the following
axis is limited to 80% of maximum acceleration.

Master value coupling with synchronized action
Axis 4 is coupled to X via a master value coupling. The acceleration response is limited to
position 80% by static synchronized action 2 from position 100.
