when the following axis posi‐
tion, required according to the
coupling rule, is in the range
of the current following axis
position.
The next tooth gap is ap‐
proached time-optimized.
The next tooth gap is ap‐
proached path-optimized.
The next segment is ap‐
proached in a time-optimized
manner, in accordance with
the ratio of the number of
gears to the number of teeth.

For rotary axes only!
The rotary axis traverses to‐
wards the synchronized posi‐
tion in the negative axis direc‐
tion. Synchronization is effec‐
ted immediately.
For rotary axes only!
The rotary axis traverses to
the synchronized position in
the positive axis direction.
Synchronization is effected
immediately.
For rotary axes only!
The rotary axis traverses to
the programmed synchron‐
ized position in time-opti‐
mized fashion. Synchroniza‐
tion is effected immediately.
For rotary axes only!
