POINT
The number of parallel branches need not match that of couplings at a parallel
coupling point.
(In the example of the diagram in Section 4.9.3 (2), the number of parallel branches
is 3 and that of couplings is 2.)
When a WAIT transition is set right after a parallel coupling, the stop completions of the
axes are not included in the waiting conditions if the parallel coupling is preceded by
motion control steps. To perform a parallel coupling on stop completions, set WAIT
transitions before a parallel coupling.

are not included in transition conditions.

Parallel coupling
When you want to perform a
coupling on stop completions
of axes started in K2 to K5,
set WAIT transition in each
route to make parallel coupling.
