(c) CAM block data setting
20 data sections may be set in a CAM block and every section may have specific curve.
1) Starting position of main axis
Set the starting position of main axis in designated section. Starting position of main axis is the same as the
ending position of main axis in previous section.
2) Ending position of main axis
Set ending position of main axis in designated section. The ending position of main axis in the last section
must be set as much as the transfer distance per 1rotation set on main/sub axis parameter.
3) Starting position of sub axis
Set the starting position of sub axis corresponding to the starting position of main axis in the designated
section. Starting position of sub axis is the same as the ending position of sub axis in previous section.
4) Ending position of sub axis
Set ending position of sub axis corresponding to the ending position of main axis in the designated section.
If control method
is “Repeat (Two-way mode), the ending position of sub axis in the last section must be 0.
If control method is “Increase(Feed mode)”, the ending position of sub axis in the last section generally has
to be set as much as the transfer distance per 1rotation set on main/sub axis parameter.
5) CAM curve
Set CAM specific curve to create data ranging from starting position of sub axis to ending position of sub
axis in the designated section. The position of sub axis is calculated by characteristic of selected CAM
curve, the position of main axis increase by point unit at the same time.
