Inch/metric switchover
The indexing positions refer to the configured system of units:
●
MD10270 POS_TAB_SCALING_SYSTEM = 0: metric
● MD10270 POS_TAB_SCALING_SYSTEM = 1: inch
Note
MD10270 defines the scaling system of the position data for the following machine data:
MD10910 INDEX_AX_POS_TAB_1
MD10930 INDEX_AX_POS_TAB_2
MD10270 affects the following setting data:
SD41500 SW_CAM_MINUS_POS_TAB_1 to
SD41507 SW_CAM_PLUS_POS_TAB_4
MD10270 is not visible in expert mode!
Entry format
● The indexing positions must be entered in the table in ascending order (starting with the
negative to the positive traversing range) with no gaps between the entries. Consecutive
position values cannot be identical.
● The axis positions must be entered in the basic coordinate system.
● If the indexing axis is defined as a rotary axis with modulo 360°(MD30300 IS_ROT_AX=1
and MD30310 ROT_IS_MODULO=1), the following points must be considered for
indexing positions:
–
Indexing positions are allowed in the range from 0° ⋜ Pos < 360°. Positions outside
this range generate alarm 4080 on power-up.
– Since the indexing axis is defined as a continuously rotating rotary axis, indexing
position 1 is approached after the highest valid indexing position in the table has been
reached 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.
