<coupling factor>
TRAILOF
N o te
The motion of a coupled-motion axis is executed in the machine coordinate system (MCS) or in a coordinate system derived
from a kinematic transformation of the MCS.
The maximum number of coupled axis groups is limited to four.
Programming example
The workpiece is to be machined on two sides with the axis configuration shown in the diagram. To do this, you create a
coupled axis group.

Fu rther information
C o upled-motion axes
A coupled-motion axis can be programmed with the full range of available motion commands (G0, G1, G2, G3, etc.). The
coupled-motion axis traverses not only the independently defined paths, but also those derived from its leading axes on the
basis of coupling factors.

Parameter 3: Coupling factor
The coupling factor specifies the desired relationship between the paths of the coupled-
motion axis and the leading axis:
<coupling factor> = path of coupled-motion axis/path of leading axis.
Type: REAL
Default: 1
The input of a negative value causes the leading axis and the coupled-motion axis to
traverse in opposite direction.
If a coupling factor is not programmed, then coupling factor 1 automatically applies.
Command for deactivating a coupled axis group
Effectiveness: modal
Programming with 2 parameters deactivates the coupling to the specified lead-
TRAILOF
ing axis:
TRAILOF(<coupled-motion axis>,<leading axis>)
Programming without specifying a leading axis produces the same result:
TRAILOF
TRAILOF(<coupled-motion axis>)
Comment
; Activation of coupled axis group, Negative cou-
pling factor: coupled-motion axis traverses in the
opposite direction from leading axis.
; Infeed of Z and W axes in opposite axis direc-
tions.
; Deactivation of coupled axis group.
