Axis couplings

Coupled motion (TRAILON, TRAILOF)

Function
When a defined leading axis is moved, the coupled motion 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 and
the coupled axis a real axis. In this way, the real axis can be traversed as a function of the
coupling factor.
• Two-sided machining with 2 coupled motion groups:
1. Leading axis Y, coupled motion axis V
2. Leading axis Z, coupled motion axis W
