Using the Electronic CAM Feature
GFK-1742A Chapter 16 Using the Electronic CAM Feature 16-19
16
Synchronization of CAM Motion with External Events
The following mechanisms allow the programmer to synchronize CAM motion with external
events:
•
The start of CAM motion can be synchronized with an external event by using the existing
WAIT command in a motion program.
•
A Cyclic CAM can be synchronized with a strobe using Local Logic variables. Refer to
Chapter 11-14 for additional information concerning Local Logic.
