Machine data
3.2 General machine data
●
Up to 60 different indexing positions can be stored in the table.
●
The 1st entry in the table corresponds to indexing position 1; the nth entry
corresponds to indexing position n.
●
The indexing positions must be entered in the table in ascending order (starting
with the negative and going to the positive traversing range) with no gaps between
the entries. Consecutive position values must not be identical.
●
If the indexing axis is defined as a rotary axis (MD30300 $MA_IS_ROT_AX = "1") with
modulo 360° (MD30310 $MA_ROT_IS_MODULO = "1"), then the position values are limited
to a
The number of indexing positions used in the table is defined by MD10900
$MN_INDEX_AX_LENGTH_POS_TAB_1.
Entering the value 1 in axial MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB assigns indexing
position table 1 to the current axis.
Special cases:
Alarm 17020 "Illegal array index" if over 60 positions are entered in the table.

Description:
The indexing position table is used to assign the axis positions in the valid unit of
measurement (mm, inches or degrees) to the indexing positions [n] on the indexing
axis. The number of indexing positions used in table 2 is defined by MD10920
$MN_INDEX_AX_LENGTH_POS_TAB_2.
These indexing positions in table 2 must be assigned valid values. Any indexing
positions in the table above the number specified in the machine data are ignored.
Up to 60 indexing positions (0 to 59) can be entered in the table.
Table length = 0 means that the table is not evaluated. If the length is not equal to
0, the table must be assigned to an axis with MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB.
If the indexing axis is defined as a rotary axis (MD30300 $MA_IS_ROT_AX = "1") with
modulo 360° (MD30310 $MA_ROT_IS_MODULO = "1"), the machine data defines the last
indexing position after which, with a further traversing movement in the positive
direction, the indexing positions begin again at 1.
Not relevant for tool magazines (revolvers, chain magazines)
Special cases:
Alarm 17090 "Value violates upper limit" if a value over 60 is entered in MD10920
$MN_INDEX_AX_LENGTH_POS_TAB_2.
