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

M3: Coupled axes
5.5 Generic coupling
Following spindle:
Example:
Programming
CPLON[S2]=(S1) CPSETTYPE[S2]="COUP"
...
CPRES=(S2)
Constraints
• 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.
5.5.8

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. Constraints and properties still apply to axis
change. The axis replacement via channel axes is released again after deactivating the
coupling module.

Type: AXIS
Range of values: All defined spindle identifiers in the channel
Comment
; Creates a coupling module for
following spindle S2 with leading
spindle S1 and activates the coupling
module. Coupling properties are set
such that they correspond to the
existing synchronous spindle coupling
type.
; Activates projected data of the
synchronous spindle coupling to
following spindle S2.
