9.2 Coupled motion TRAILON, TRAILOF
Programming
TRAILON(FAxis,LAxis,Coupling)
TRAILOF(FAxis,LAxis,Axis2)
Explanation of the commands and parameters
TRAILON
Activate and define coupled axes; modal
TRAILOF
Deactivate coupled axes
FAxis
Axis name of trailing axis
LAxis
Axis name of trailing axis
Coupling
Coupling factor = Path of coupled-motion axis/path of trailing axis
Default = 1
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
•
Traversing of an axis by a simulated axis. The
leading axis is a simulated axis and the trailing
axis is a real axis. The real axis can thus be
traversed with allowance for the coupling factor.
•
Two-sided machining with 2 combined axis pairs:
1st leading axis Y, trailing axis V
2nd leading axis Z, trailing axis W
