Overview of Inject and Clamp Mode
Chapter 1
1-14
After completing the last configured open profile, the QDC module either
switches immediately to the first programmed segment of the open slow
profile, or waits for a command from your PLC-5 program to continue.
Open Slow
Use the open slow profile to accurately position the clamp for ejecting the
part(s). You may decelerate clamp motion twice with this profile using up
to two profile segments (Figure 1.15).
You may select from these control modes:
velocity vs. position
pressure vs. position
