Function
With the axial leading value coupling, a leading and
a following axis are moved in synchronism. It is
possible to assign the position of the following axis
via a curve table or the resulting polynomial uniquely
to a position of the leading axis – simulated if
necessary.
Leading axis
is the axis which supplies the input
values for the curve table.
Following axis
is the axis which takes the positions
calculated by means of the curve table.
X
Y
The leading value coupling can be activated and
deactivated both from the part program and during
the movement from synchronized actions.
The leading value coupling always applies in the
basic coordinate system.
For information about creating curve table, see Chapter
"Curve tables" in this chapter.
For information about leading value coupling, see /FB/,
M3, Coupled Motion and Leading Value Coupling.
