Axis-specific machine data

Indexing axis
An axis is defined as indexing axis by assigning an indexing position table to this axis, using
the following axis-specific machine data:
MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB = <value>
<Value> Meaning
Indexing position tables
In the indexing position tables, the indexing positions are saved in mm, inches or degrees.
Presently, a total of two indexing position tables are available.
MD10910 $MN_INDEX_AX_POS_TAB_1 [ <n> ] (indexing position table 1)
MD10930 $MN_INDEX_AX_POS_TAB_2 [ <n> ] (indexing position table 2)
with <n> = 0 ... (maximum number - 1)
Multiple table assignment
Several axes can be assigned to an indexing position table.
Precondition: the axes are of the same type (linear axis, rotary axis, modulo 360° function)
General supplementary conditions
● The indexing positions must be listed in the indexing position table without gaps in an
ascending order.
● Indexing positions that follow one another must not be identical.
● The indexing positions must be specified in the basic coordinate system.
