assigns the machine axis the relevant table of indexing positions and also defines the
machine axis as an indexing axis.
Indexing position tables
The indexing positions are stored in one of two possible tables.
• MD10900 INDEX_AX_LENGTH_POS_TAB_1 (number of positions of indexing table 1)
• MD10910 INDEX_AX_POS_TAB_1[n] (indexing position table 1)
• MD10920 INDEX_AX_LENGTH_POS_TAB_2 (number of positions of indexing table 2)
• MD10930 INDEX_AX_POS_TAB_2[n] (indexing position table 2)
