16.3 Parameterization of indexing axes
Definition of the indexing axis
An axis (linear or rotary axis) can be defined as indexing axis with the axial machine data:
MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB
Value
0
1
2
Indexing position tables
The axis positions (in mm or degrees) assigned to the indexes must be stored for each
indexing axis in the form of a table in machine data.
Two indexing position tables are possible:
MD10910 $MN_INDEX_AX_POS_TAB_1 [n] (indexing position table 1)
MD10930 $MN_INDEX_AX_POS_TAB_2 [n] (indexing position table 2)
Note
Several axes can be assigned to an indexing position table. On condition that these indexing
axes are of the same type (linear axis, rotary axis, modulo 360° function).
No. of indexing positions
Up to 60 positions can be entered in each indexing position table:
[n = 0 ... 59]
The actually used number of entries is defined with the machine data:
MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1 ((number of positions of indexing
position table 1)
MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2 ((number of positions of indexing
position table 2)
Note
Entries in the indexing positions table that cross the parameterized number of indexing
positions (MD10900 or MD10920) are not considered.

Description
The axis is not declared as an indexing axis.
The axis is an indexing axis. The associated indexing positions are stored in the indexing
positions table 1.
The axis is an indexing axis. The associated indexing positions are stored in the indexing
positions table 2.
