Important: For the QDC module to operate in the inject, clamp, and eject
mode, you must connect position sensors to these two inputs:
input 1 (screw position)
input 3 (clamp position)
ATTENTION: Your control system may not work as expected
with possibly machine damage if you attempt to control a
pressure profile of a phase (inject, clamp, or eject) not
hydraulically plumbed for pressure control.
Because system pressure may change from one phase to the next, we
recommend that you:
assign pressure control to phases that require pressure profiles
(and are hydraulically plumbed to support it)
place the system pressure sensor accordingly in the hydraulic circuit
configure the remaining phases with velocity profiles
