Cam positions

Setting cam positions
The positions of the plus and minus cams are defined using general setting data:
● SD41500 SW_CAM_MINUS_POS_TAB_1[n]
● SD41501 SW_CAM_PLUS_POS_TAB_1[n]
● SD41502 SW_CAM_MINUS_POS_TAB_2[n]
● SD41503 SW_CAM_PLUS_POS_TAB_2[n]
● SD41504 SW_CAM_MINUS_POS_TAB_3[n]
● SD41505 SW_CAM_PLUS_POS_TAB_3[n]
● SD41506 SW_CAM_MINUS_POS_TAB_4[n]
● SD41507 SW_CAM_PLUS_POS_TAB_4[n]
Note
Owing to the grouping of cam pairs (eight in each group), it is possible to assign different access
authorization levels (e.g. for machine-related and workpiece-related cam positions). The
positions are entered in the machine coordinate system. No check is made with respect to the
maximum traversing range.
