Examples
Example 1: Dynamic configuration of a master/slave coupling
Dynamic configuration of a master/slave coupling from the part program.
The axis relevant after axis container rotation is to become the master axis.
Program code
MASLDEF(AUX,S3)
MASLON(AUX)
M3=3 S3=4000
MASLDEL(AUX)
AXCTSWE(CT1)
Example 2: Actual-value coupling of a slave axis
Actual value coupling of a slave axis to the same value of the master axis using
PRESETON. For a permanent master/slave coupling, the actual value at the slave axis is to
be changed using PRESETON.

11.7 Master/slave coupling (MASLDEF, MASLDEL, MASLON, MASLOF, MASLOFS)
Comment
; S3 master for AUX
; Close coupling for AUX
; Clockwise direction of rotation
; Delete configuration and open the coupling
; Container rotation
Axis couplings
Comment
; Briefly switch-out the
permanent coupling.
; Temporary coupling open.
; Set the actual value of
the non-referenced slave
axes as these are
activated with Power On.
; Activate permanent
coupling.
