14.5 Generic coupling
Boundary conditions
● The switch command CPDEL results in a preprocessing stop with active coupling.
Exception: CPSETTYPE="COUP" does not result in a preprocessing stop.
● Applying CPDEL to a coupling module active in the block preparation results in implicit
deactivation of this coupling.
● Applying CPDEL to an undefined coupling module does not result in any action.

Defining leading axes (CPLDEF or CPDEF+CPLA)

The leading axes/spindles defined for a coupling can be programmed/created with the
keyword CPLDEF or with the keyword CPLA in conjunction with CPDEF.

Coupling Lead Axis Definition
Definition of leading axis/spindle for following axis/spindle FAx. A leading
axis/spindle module is created in the coupling module. If the coupling
module of the following axis/spindle has not yet been created, the cou‐
pling module will be created implicitly.
Type: AXIS
Range of values: All defined axis and spindle names in the channel
