Traversing of indexing axes by PLC

Indexing axes can also be traversed from the PLC user program.
There are various methods:
● Concurrent positioning axes
● Asynchronous subprograms (ASUBs)

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.
2 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).
Extended Functions
Function Manual, 03/2013, 6FC5397-1BP40-3BA1
The indexing position to be approached can be specified by the PLC (see Section "P2:
Positioning axes (Page 599)").

Meaning
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.
