Selection/deselection of axes couplings

A coupling group can be activated by the following NC command:

#ENABLE AX LINK [ < coupling_group> ]

#ENABLE AX LINK (Coupling group 0, defined in the channel parameter list)

or alternative

#AX LINK ON [ < coupling_group> ]

oder

#AX LINK ON (Coupling group 0, defined in the channel parameter list)

An active coupling group can be de-activated by the following NC commands:

#DISABLE AX LINK [ < coupling_group > ]

#DISABLE AX LINK   (Deselection of the latest activated coupling group )

or alternative

#AX LINK OFF [ < coupling_group > ]

#AX LINK OFF (Deselection of the latest activated coupling group )

#AX LINK OFF ALL (Deselection of all active coupling groups )

Handling and method of operation:

No coupling group is active after startup in the initial position of the NC kernel. The axes coupling is effective when it is enabled in the NC program. Provided that it is not disabled, per default it ends at the program end (M30, M02). If active axes couplings should be effective for the next program (program global), a specific channel parameter [1]-39 has to be set.
At the same time multiple coupling groups can be enabled.
Unassigned coupling groups cannot be activated. A coupling group is considered assigned if at least one valid master-slave coupling pair has been defined.
The NC command must be a single instruction in the NC block.
The number of the coupling group may also be programmed in mathematical expressions.
Before selection or deselection of synchronous mode the TRC must be deselected.
Manual mode with parallel interpolation (G201) may not be active for the slave axes when synchronous mode is selected
Positions of slave axes cannot be programmed when synchronous mode is active.

Programming example

Used axes designations: Master axis system X, Y, Z, C

Slave axis system Y_S, Z_S, C_S

(Initialization program) 
%L UP_INIT_ACHS_KOPPL 
(initialize axis coupling 1) 
N10 #SET AX LINK[1, Y_S=Y, Z_S=Z, C_S=C] 
(or #AX LINK[1, Y_S=Y, Z_S=Z, C_S=C] 
N20 M17 
(tool changing program) 
%L UP_WZ 
N30 #DISABLE AX LINK (or #AX LINK OFF) 
(Approach tool changing position) 
N40 G01 G90 Y1000 Z100 C0 Y_S=1000 Z_S=100 C_S=0 
(Tool change; T10 contains all tool axis offsets and the tool lengths of master and slave tools; or these values are explicitly included in the calculation.)

(Approach old coupling position. The coupling position may also be defined 
via parameter programming, and then be used by the subroutine.)
