Type: AXIS
Range of values:All defined axis and spindle names in the channel
Type: AXIS
Range of values:All defined axis and spindle names in the channel
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 values:± (2,2 * 10-308 ... 1,8 * 10+308)
Default value: +1.0
Comment
