Comment
; Leading axis X1 is traversed to position 280.
; The current position X1=280 is taken as
synchronized position of the leading axis. The
previously active synchronized position of the
leading axis (200) becomes ineffective.
The coupling is closed time-
optimized.
The coupling is only closed
when the following axis
position, required according
to the coupling rule, is in the
range of the current
following axis position.
The next tooth gap is
approached time-optimized.
The next tooth gap is
approached path-optimized.
The next segment is
approached in a time-
optimized manner, in
accordance with the ratio of
the number of gears to the
number of teeth.
