21.3 Parameterization of indexing axes
Definition of the indexing axis
An axis (linear or rotary axis) can be defined as an indexing axis with the aid of the axial
machine data MD30500 INDEX_AX_ASSIGN_POS_TAB. The number of the indexing
position table (1 or 2) must be entered in the machine data.
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). Otherwise alarm
4080 "Incorrect configuration for indexing axis in MD [Name]" is output during ramp-up.
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. Any value can be entered for the
distance between the individual indexing positions.
Note
Up to two indexing position tables are permitted:
MD10910 INDEX_AX_POS_TAB_1 [n]
MD10930 INDEX_AX_POS_TAB_2 [n]
The indexing positions are metric.
Number of entries for each table
Up to 60 positions can be entered in each indexing position table:
[n = 0 ... 59]
The actual number of entries used must be defined with the machine data for table 1 or 2:
MD10900 INDEX_AX_LENGTH_POS_TAB_1
MD10920 INDEX_AX_LENGTH_POS_TAB_2
All positions entered in the table which are higher than the number defined in the machine
data are inactive.
