4.4 Generic coupling
Selective switch-on/off with three leading axes
A coupling module is created and activated with following axis X2 and leading axes X1, Z
and A.
N10 CPDEF=(X2) CPLA[X2]=(X1) CPLA[X2]=(Z) CPLA[X2]=(A)
N20 CPON=(X2)
N30 CPOF=(X2)
N40 CPLON[X2]=(X1)
N50 CPLON[X2]=(A)
N60 CPLON[X2]=(Z) CPLOF[X2]=(A)
N70 CPLOF[X2]=(X1)
Definition/deletion of a coupling module
With CPDEF a coupling module is created and activated with following axis X2 and leading
axes X1 and Z. The coupling is not activated. Following axis X2 does not follow the coupling
rule!
CPDEF=(X2) CPLA[X2]=(X1) CPLNUM[X2,X1]=2 CPLA[X2]=(Z) CPLNUM[X2,Z]=3
...
Activation can be done with CPON, deactivation with CPOF.
After the deactivation of the coupling relationship to all leading axes, the coupling object can
be deleted. Reserved memory is released:

; All leading axes become active, i.e. all
contribute a position component according to
the coupling rule (coupling component) to axis
X2.
; All leading axes are deactivated.
; Leading axis X1 is activated, only this axis
supplies a coupling component. Leading axes Z
and A remain deactivated.
; Leading axis X1 remains active, leading axis A
is deactivated, X1 and A contribute coupling
components (→ selective switch-on is additive,
the condition of the other leading axes is
retained).
; Leading axis Z is activated, leading axis A
deactivated. Leading axes X 1and Z are now
active.
; Leading axis X1 is deactivated. Leading axis Z
remains active.
