Cross-Channel Coupling, Axis Replacement - Siemens SINUMERIK 840D Function Manual

Example:
Programming
CPLON[S2]=(S1) CPSETTYPE[S2]="COUP"
...
CPRES=(S2)
Boundary conditions
● CPRES is only allowed when the coupling type "Synchronous spindle"
(CPSETTYPE="COUP") is set.
● Application of CPRES to an already active coupling results in a new synchronization.
● Applying CPRES to an undefined coupling module does not result in any action.

Cross-channel coupling, axis replacement

The following and leading axes must be known to the calling channel.
Following axis
The following axis is requested for replacement in the channel when programming a CP
keyword in the part program, depending on the axis replacement projection (MD30552) with the
language command GETD.
Axis change of the following axis after activating the coupling module is only permitted in the
channel. Changing from channel to main run and vice versa is still possible, however a change
across channel boundaries is not. Supplementary conditions and properties still apply to axis
change. The axis replacement via channel axes is released again after deactivating the
coupling module.

Leading axes
Axis change of leading axes can be performed independently of the state of the coupling.

14.5 Generic coupling
Comment
; Creates a coupling module for follow-
ing spindle S2 with leading spindle S1
and activates the coupling module. Cou-
pling properties are set such that they
correspond to the existing synchronous
spindle coupling type.
; Activates projected data of the syn-
chronous spindle coupling to following
spindle S2.
