Preface
P-2
Before attempting to apply the QDC module to a molding machine we
assume that you are:
an injection molding professional
an experienced programmer (especially with A-B PLC-5 processors)
familiar with hydraulics
We use these abbreviations:

The following table presents other terms we use in this manual:
Term: Definition:
Selected Valve In multiĆvalve systems, depending on the configured profile, the QDC
module controls one valve and presets the setting of the remaining
valves to produce moldingĆmachine profiles. We call the valve being
controlled by the QDC module's algorithms the selected valve.
Multiple axis of control, such as the clamp and ejector cylinders, may
require additional control valves.
UnĆselected Valves In multiĆvalve systems, depending on the configured profile, the QDC
module controls one valve and presets the remaining valves to
produce moldingĆmachine profiles. We call the valves that are
preset with an open loop percentage setpoint the unĆselected valves.
Profile A group of mold/part setpoints which define a given machine
operation to the QDC module.
Command Block Blocks downloaded from the PLC data table to the QDC module to
make configuration changes or to initiate machine actions.
Status Block Blocks used by the QDC module to relay information to the PLC
processor about the QDC module's current operating status.
Profile Block Command block containing mold/part setpoints.
Configuration Block Command block containing machine setpoints.
Direct Acting Valve An analog control valve that delivers increasing velocity or pressure
with increasing signal input.
Reverse Acting Valve An analog control valve that delivers increasing velocity or pressure
with decreasing signal input.
