9.2 Coupled motion (TRAILON, TRAILOF)
9.2
Function
When a defined leading axis is moved, the trailing axes
(= following axes) assigned to it traverse through the distances described by the leading
axis, allowing for a coupling factor.
Together, the leading axis and following axis represent coupled axes.
Applications
• Traversal of an axis by means of a simulated axis. The leading axis is a simulated axis
• Two-side machining with 2 coupled axes:
Programming
TRAILON(Faxis,Laxis,Coupling)
or
TRAILOF(Faxis,Laxis,LAxis2)
or deactivate without specification of leading axis
TRAILOF(FAxis)
TRAILON and TRAILOF act modal.

and the coupled axis a real axis. In this way, the real axis can be traversed as a function
of the coupling factor.
1st leading axis Y, coupled axis V
2nd leading axis Z, coupled axis W
