Indexing Axes (T1)
Traversing of indexing axes
Signal from PLC "Indexing axis in position"
During the traversing motion of the indexing axis in the JOG mode, the following NC/PLC
interface signal displays the reaching of the indexing position:
DB31, ... DBX76.6 (indexing axis in position)
Prerequisite: The indexing axis is referenced (DB31, ... DBX60.4 bzw. 5 = 1)
Alarms in JOG mode
If the indexing axis leaves the traversing range defined in the indexing position table when
traversing in JOG mode, alarm 20054 "wrong index for indexing axis in JOG" is output.
Revolutional feedrate
In JOG mode, the response of the axis/spindle also depends on the setting data:
SD41100 $SN_JOG_REV_IS_ACTIVE (revolutional feed rate for JOG active)
SD41100
= 1 (active)
= 0 (not active)

Description
The axis/spindle is always traversed with rrevolutional feed rate as a function of
the master spindle:
MD32050 $MA_JOG_REV_VELO (revolutional feed rate for JOG mode)
or
MD32040 $MA_JOG_REV_VELO_RAPID (revolutional feed rate for JOG with
rapid traverse override)
The response of the axis/spindle depends on the setting data:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE(revolutional feed feed rate
for position axes/spindles)
The response of a geometry axis on which a frame acts is to rotate, depending
on the setting data:
SD42600 $SC_JOG_FEED_PER_REV_SOURCE
