Switch off (TRAILOF)

Switch off of the coupling of a coupled-motion axis with a leading axis takes place through
the TRAILOF part program command.

Type AXIS
:
Range of val‐ All defined axis and spindle names in the channel
ues:
The ratio of the traversing movement of the coupled motion axis to the
leading axis is specified via the optional coupling factor:
Coupling factor = Path of the coupled-motion axis/path of the leading
axis
A negative coupling factor results in motion in opposite directions for
the leading and coupled motion axis.
Type REAL
:
Range of val‐ ± (2,2 * 10-308 ... 1,8 * 10+308)
ues:
Default value: +1.0
