13.13 Master/slave grouping (MASLDEF, MASLDEL, MASLOF, MASLOF, MASLOFS)
Example of the dynamic configuration of a master/slave coupling
Dynamic configuration of a master/slave coupling from the parts program:
The axis relevant after axis container rotation must become the master axis.
MASLDEF(AUX,S3)
MASLON(AUX)
M3=3 S3=4000
MASLDEL(AUX)
AXCTSWE(CT1)
Example of the actual-value coupling of a slave axis
Actual-value coupling of a slave axis set to the same value as the master axis with
PRESETON.
In a permanent master/slave coupling, the actual value on the SLAVE axis is to be changed
by PRESETON.

Example of a coupling sequence Position 3 / Container CT1
To enable coupling with another spindle after container rotation, the previous coupling must
be uncoupled, the configuration cleared, and a new coupling configured.
Initial situation:
Direction of rotation
of the container
13-54
;S3 master for AUX
;Coupling in for AUX
;Clockwise rotation
;Clear configuration and
;disconnect the coupling
;Container rotation
;Activate permanent coupling
;Temporary coupling off
;Set actual value of the unreferenced
;slave axes because they are activated
;on Power on
;Activate permanent coupling
