M3: Coupled axes
8.5 Generic coupling
The basic motion is path motion with extremely low velocity in the positive direction. A larger
DRF correction motion applies to this in the opposite direction. This results in a travel command
in the negative direction. If these movements are now stopped using a CP-SW limit stop, then
for standard machine data, this means that DRF motion is canceled, and only path motion is
continued after the stop is withdrawn.
NCU link
The following restriction must be taken into account for cross-NCU couplings based on lead-
link axis and axis container:
As the leading axis can be interpolated on another NCU, it can take between one and two IPO
cycles for the brake to be transferred to the NCU of the leading axis.

Examples

Example 1: Generic coupling type "freely programmable" (CPSETTYPE[FAx] = "CP")
Configuration:
MD26110 $MA_POS_LIMIT_PLUS[AX2]=15 ;
MD30455 $MA_MISC_FUNCTION_MASK[AX2] =
'H800' ;
Programming:
; start position of X and Y
N100 G0 X0 Y0
; coupling activation FA=Y LA=X
; set with CPMBRAKE bit 0 (transfer of the brake to the leading axis)
N120 CPON=Y CPSETTYPE="CP" CPLA=X CPLDEN=2 CPMBRAKE B_OR='H1'
N140 G4 F2
; traverse leading axis X
N200 G1 X=1000 F1000
Example 2: Couplings with a maximum of one active leading axis/spindle
With the following calls, the CP-SW limit monitoring is executed – including the transfer of the
brake to the leading axis – if MD30455 MA_MISC_FUNCTION_MASK[AX2] bit 11 is set:
TRAILON(Y,X,0.5) ;
432
