SINUMERIK 840Di Manual (HBI) – 06.03 Edition
Indexing axis are rotary or linear axes that may only be traversed within their
traversing range to defined positions, the indexing positions.
Traversing to indexing positions using the parts program or manually is only
effective if the corresponding machine axis has been successfully referenced.
The indexing positions are stored in tables.
The machine data
S
MD 30500: INDEX_AX_ASSIGN_POS_TAB[n] (axis is indexing axis)
assigns the machine axis the relevant table of indexing positions and also
defines the machine axis as an indexing axis.
The indexing positions are stored in one of 2 possible tables.

MD10900: INDEX_AX_LENGTH_POS_TAB_1 (number of positions of in-
dexing table 1)
S
MD10910: INDEX_AX_POS_TAB_1[n] (indexing position table 1)
S
MD10920: INDEX_AX_LENGTH_POS_TAB_2 (number of positions of in-
dexing table 2)
