Master/Slave Group (Masldef, Masldel, Maslon, Maslof, Maslofs) - Siemens Sinumerik 840D sl Programming Manual

9.6 Master/slave group (MASLDEF, MASLDEL, MASLON, MASLOF,
MASLOFS)
Function
The master/slave coupling in SW 6.4 and lower permitted coupling of the slave axes to their
master axis only while the axes involved are stopped.
Extension of SW 6.5 permits coupling and uncoupling of rotating, speed-controlled spindles
and dynamic configuration.
Syntax
MASLON(Slv1,Slv2,..., )
MASLOF(Slv1,Slv2,..., )
MASLDEF(Slv1,Slv2,..., master axis)
MASLDEL(Slv1,Slv2,..., )
MASLOFS(Slv1, Slv2, ..., )
Note
For MASLOF/MASLOFS, the implicit preprocessing stop is not required. Because of the
missing preprocessing stop, the $P system variables for the slave axes do not provide
updated values until next programming.

9.6 Master/slave group (MASLDEF, MASLDEL, MASLON, MASLOF, MASLOFS)

Close (switch-in) a temporary coupling.
Open an active coupling. The extensions for spindles must be
observed.
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.
