15.7 Special features of indexing axes
DRF
An additional incremental work offset can also be generated for indexing axes in
AUTOMATIC mode with the handwheel using the
DRF function.
Software limit switch
The software limit switches are also effective during traversing movements once the indexing
axis has been referenced.
In handwheel traversing with JOG continuous or JOG incremental, the indexing axis stops at
the indexing position ahead of the software limit switch.
Reference point approach
When reference point is reached::
DB31, ... DBX60.4 or 60.5 (referenced/synchronized 1 or 2) = 1
the indexing axis moves only to indexing positions in JOG continuous and JOG incremental
mode.
If the axis is not referenced:
DB31, ... DBX60.4 or 60.5 (referenced/synchronized 1 or 2) = 0,
the indexing positions are ignored when traversing in JOG mode!
Since the axis positions stored in the indexing position tables only correspond to the
machine positions when the axis is referenced, an NC start must be disabled for as long as
the indexing axis is not referenced.
Position display
Positions on indexing axes are displayed in the units of measurement normally used for the
axes (mm, inches or degrees).
Abort through RESET
RESET causes the traversing movement on an indexing axis to be aborted and the axis to be
stopped. The indexing axis is no longer positioned on an indexing position.
