MD10910 $MN_INDEX_AX_POS_TAB_1[ 6 ] = 270
MD10910 $MN_INDEX_AX_POS_TAB_1[ 7 ] = 315
Length of the indexing position table (1)
MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1= 8
Defining machine axis AX5 as rotary modulo axis and indexing axis
MD30300 $MA_IS_ROT_AX[ AX5 ] = 1
MD30310 $MA_ ROT_IS_MODULO [AX5] = 1
MD30500 $MA_INDEX_AX_ASSIGN_POS_TAB [AX5] = 1
Example 2: Indexing axis as linear axis
Machine axis AX6 is a workholder with 10 locations. The distances between the 10 locations
are different. The first location is at position -100 mm. Machine axis is AX6.
