MD10910 INDEX_AX_POS_TAB_1[6] = 270
MD10910 INDEX_AX_POS_TAB_1[7] = 315
Other machine data:
MD10900 INDEX_AX_LENGTH_POS_TAB_1= 8
MD30500 INDEX_AX_ASSIGN_POS_TAB [AX5] = 1
MD30300 IS_ROT_AX [AX5] = 1
MD30310 ROT_IS_MODULO [AX5] = 1
Example of indexing axis as linear axis
Workholder with ten locations.
The distances between the ten locations are different. The first location is at position -100
mm.
Figure 21-2
The indexing positions for the workholder are entered in table 2:
MD10930 INDEX_AX_POS_TAB_2[0] = -100
MD10930 INDEX_AX_POS_TAB_2[1] = 0
MD10930 INDEX_AX_POS_TAB_2[2] = 100
MD10930 INDEX_AX_POS_TAB_2[3] = 200
MD10930 INDEX_AX_POS_TAB_2[4] = 300
MD10930 INDEX_AX_POS_TAB_2[5] = 500
MD10930 INDEX_AX_POS_TAB_2[6] = 700
MD10930 INDEX_AX_POS_TAB_2[7] = 900
MD10930 INDEX_AX_POS_TAB_2[8] = 1250
MD10930 INDEX_AX_POS_TAB_2[9] = 1650
