Important: If you need only one open slow motion, configure only the 1st
segment of the open slow profile.
In this section, we describe the eject operation for expelling molded parts.
The operation consists of:
ejector advance
ejector retract

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 your PLC program
You may advance the ejector while the clamp is still opening the mold, or
wait until the mold is fully open.
