Spindle states
The following table shows the reactions that occur when PRESETONS is used on a spindle in
a synchronized action:

Axis couplings
● Leading axes: The sudden change of the leading axis position caused by PRESETONS is
not traversed in the following axes. The coupling is not changed.
● Following axes: Only the overlaid position component of the following axis is affected by
PRESETONS.
Gantry grouping
● If PRESETONS is used on the guide axis of a gantry grouping, the work offset is also
performed in all synchronized axes of the gantry grouping.
Indexing axes
● PRESETONS can be used on indexing axes.
