Master axis
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 must become the master axis.
Program code
MASLDEF(AUX,S3)
MASLON(AUX)
M3=3 S3=4000
MASLDEL(AUX)
AXCTSWE(CT1)
Examples
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.

Coupling user-defined using machine data or also
create/change from the part program.
Open the coupling analog to MASLOF and automatically brake
the slave spindle.
Uncouple master/slave axis group and delete group definition.
Slave axes led by a master axis.
Axis, that controls defined slave axes in a master/slave group.
Comments
