10.4.23 Leading value coupling LEADON, LEADOF
Function
The axial leading value coupling can be
programmed in synchronized actions without
restriction.
Activate axial leading value coupling:
...DO LEADON(FA,LA,NR)
where: FA: Following axis
LA: Leading axis
NR: Number of stored
curve table
Deactivate axial leading value coupling:
...DO LEADOF(FA,LA)
where: FA: Following axis
LA: Leading axis
The axis to be coupled is released for synchronized
action access by invoking the RELEASE function for the
axis.
Example:
RELEASE (XKAN)
ID=1 every SR1==1 to LEADON(CACH,XKAN,1)
Programming example
On-the-fly parting
A continuous material that runs continuously through the work area of parting device is to be
separated into pieces of equal length.
X axis: Axis in which the continuous material runs. WCS
X1 axis: Machine axis of the continuous material, MCS
Y axis: Axis in which the parting device "travels" with the continuous material
It is assumed that the positioning and control of the parting tool is controlled by the PLC. The
signals of the PLC interface can be evaluated for the purpose of determining the degree of
synchronism between the continuous material and the parting tool.
Actions Activate coupling, LEADON
Deactivate coupling, LEADOF
Set actual value, PRESETON
