4. Enable Local Logic by setting the %Q offset 1 bit from the PLC. If there are no errors, we can
then execute the motion programs.
5. Execute Program 1 by toggling %Q offset 2 bit. The motor connected to Axis #1 should then
begin to execute Motion Program #1.
6. Execute Program 2 by toggling %Q offset 3 bit. The motor connected to Axis #2 should begin
to execute Motion Program #2.
7. The motors will execute the statements until they reach the first DWELL, where we can
visually verify that it followed the CAM profile correctly. The display should be similar to
Figure 16-39. Notice how the commanded position for Axis#2 equals 2500, while the
commanded position for the slave corresponds to the CAM table and has the value 10,000.

Once the dwell time is finished, the motors will continue executing the statements until they reach
the second DWELL where we can visually verify that it followed correctly. The display should be
similar to Figure 16-40. Notice how the commanded position for Axis#2 equals 47500, while the
slave commanded position corresponds to the CAM table and has the value 11,000.
