Figure 3.8.18 Material is misplaced
Using E-Cam output angle and the sensor could avoid and detect the material that is placed in a
wrong position. See Figure 3.8.19, when DO.0x118 is On, if the sensor does not detect the
material, it might mean the material is in a wrong position. To avoid wrong cutting, anti-cut
procedure should be activated.

Figure 3.8.19 Anti-cut detection
When anti-cut PR is triggered, enable macro F to calculate the moving distance between current
and target position (0 degree of the cutting curve) first. Then, use macro 8 to stop the slave axis
for a cycle and make it return to 0 degree. See Figure 3.8.20. When E-Cam is engaged, macro F
can write the correcting amount (= the position error between current and target position) into the
specified PR data.
