CPOF=(X2) CPLA[X1]=(Z)
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.

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!

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:

; The coupling with leading axis Z is
deactivated with CPOF, the coupling with
leading axis X1 is retained. The created
coupling module remains created.
; 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.
