Ejector Advance
The QDC module starts advancing the ejector after detecting either one of
these events that you configure/program:
clamp position reaching a pre-determined setpoint
command from the user PLC program
You may advance the ejector while the clamp is still opening the mold, or
wait until the mold is fully open.
Up to three ejector advance profile segments may be used. You may select
from these control modes:
velocity vs. position
pressure vs. position
