Detailed description
2.5 Generic coupling
Boundary conditions
• CPRES is only allowed when the coupling type "Synchronous spindle"
• 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.
2.5.7 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 creating the coupling
module in the parts program, depending on the axis replacement projection (MD30552) with
the language command GETD.
Axis change of the following axis is then 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. Boundary conditions and properties still apply to axis change.

Leading axes
Axis change of leading axes can be performed independently of the state of the coupling.
2.5.8 Behavior with rotary axes
Rotary axes as leading or following axes
It is possible to couple rotary axes to a linear axis and vice versa. Note that a direct
assignment of degrees to mm must be performed using the coupling rule.
Programming example:
A = Rotary axis, X = Linear axis
N10 G0 A0 X0
N20 CPON=(A) CPLA[A]=(X) CPLNUM[A,X]=2
N30 X100
120
(CPSETTYPE="COUP") is set.
; Traverse motion:
X = 0 mm, A = 0 degrees
; A coupling module for rotary axis A with
linear axis X as leading axis is created
and activated. The coupling value is 2.
; Traverse motion:
X = 3,94 in, A = 200 degrees (= 100*2)
