Signal state 0 The axis is not involved in the path.
Note for the reader Function Manuals
DB390x
DBX1002.5
Positioning axis
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The NCK handles the axis as positioning axis. This means that it has:
• its own axis interpolator (linear interpolator)
• its own feedrate (F value)
• its own feedrate override
• exact stop (G09) at the progr. end position
Signal state 0 The axis is not a positioning axis.

DB390x
DBX1002.6
Indexing axis in position
Signal(s) from axis / spindle (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The signal is dependent on "Exact stop fine":
The signal is set if "Exact stop fine" is reached. The signal is reset when
exiting "Exact stop fine".
• The indexing axis is located on an indexing position.
• The indexing axis has been positioned with instructions for "Coded
Position".
Signal state 0 The axis is not defined as an indexing axis.
• The indexing axis travels: DB390x DBX4.7/.6 (travel command +/-) is
present.
• The indexing axis is located at a position which is not an indexing
position, e.g.:
– For JOG after termination of travel movement, e.g. with RESET
– in the Automatic mode: the indexing axis has, for example,
approached a selected position controlled by an AC or DC
instruction
• The indexing axis has not been positioned with instructions for "coded
position" (CAC, CACP, CACN, CDC, CIC) in the automatic mode.
• The "Controller enable" signal for the indexing axis has been withdrawn:
DB380x DBX2.1 (controller enable)
Application Tool magazine: Activation of the gripper to remove the tool from the
magazine is initiated as soon as the indexing axis is in position.
The PLC user program must ensure this happens.
Special cases, errors, ...
• The axis positions entered in the indexing position table for the individual
divisions can be changed using work offsets (including DRF).
• If a DRF is applied to an indexing axis in AUTOMATIC mode, then
interface signal "Indexing axis in position" remains active even though
the axis is no longer at an indexing position.
corresponding to ... MD30500 INDEX_AX_ASSIGN_POS_TAB (axis is an indexing axis)
