Valid measuring system
The indexing positions defined with MD10900 and MD10920 are related to the measuring
system configured for position tables:
MD10270 $MN_POS_TAB_SCALING_SYSTEM
Value
0
1
Note
MD10270 has an effect on the following setting data:
SD41500 $SN_SW_CAM_MINUS_POS_TAB_1 (switching point for falling cam edge 1-8)
to
SD41507 $SN_SW_CAM_PLUS_POS_TAB_4 (switching point for rising cam edge 25-32).
Entry for indexing positions
The following rules apply:
● The indexing positions must be entered in the table in ascending order (starting with the
● Consecutive position values cannot be identical.
● The axis positions must be entered in the basic coordinate system.
Modulo rotary axis as indexing axis
The indexing axis is defined with Modulo 360° as rotary axis:
MD30300 $MA_IS_ROT_AX = 1
and
MD30310 $MA_ROT_IS_MODULO = 1
In this case, the following points must be observed additionally for the specification of the
indexing positions:
● Permissible range: 0° ≤ Pos < 360°
● Since the indexing axis is defined as a continuously rotating rotary axis, indexing position

negative to the positive traversing range) with no gaps between the entries.

and the axis continues to traverse in the positive direction with INC. Similarly, indexing
position 1 is followed by the highest valid indexing position in the negative direction with
INC.
