15.2.1 Traversing of indexing axes in the JOG mode
Reference point approach
An indexing axis approaches the reference point in the same way as other axes. The
reference point does not have to coincide with an indexing position.
When reference point is reached:
DB31, ... DBX60.4 or 5 (referenced/synchronized 1 or 2) = 1
the indexing axis moves only to indexing positions in JOG mode during conventional and
incremental traversing.
Exception: No indexing positions are approached when traversing with the handwheel.
If the axis is not referenced (DB31, ... DBX60.4 or 5 = 0), the indexing positions are ignored
when traversing in JOG mode!
Note
Hirth indexing axes cannot be traversed in JOG mode before reference point approach.
Continuous traversal in JOG
● Jog mode active:
SD41050 $SN_JOG_CONT_MODE_LEVELTRIGGRD = 1
Pressing a "+" or "-" traversing key causes the indexing axis to move in the same way as
with conventional JOG traversing. When the traversing key is released, the indexing axis
traverses to the next indexing position in the direction of traversing.
● Continuous mode active:
SD41040 $SN_JOG_CONT_MODE_LEVELTRIGGRD = 0
Pressing the traversing key briefly (first rising signal edge) starts the traversing movement
of the indexing axis in the desired direction. Traversing continues when the traversing key
is released. When the traversing key is pressed again (second rising signal edge), the
indexing axis traverses to the next indexing position in the direction of traversing.
Indexing axes are generally traversed in JOG mode (standard setting). Continuous mode
plays a less important role.
If the operator changes the direction of traversing before the indexing position has been
reached, the indexing axis is positioned on the next indexing position in the direction of
traversing. The traversing movement must be started in the opposite direction.
For further information on continuous traversing in JOG or continuous mode (see Section
"H1: Manual and handwheel travel (Page 143)").
