EndĆof Segment Position Setpoints
End-of Segment Position Setpoints are dictated by the particular mold,
clamp, and ejector configuration on your plastic molding machine. In
general:
You are not required to enter any clamp or ejector End-of Segment
Position Setpoints. If your profile setpoint entries are configured
without End-of Segment Position Setpoints, the following are observed
during all clamp and ejector movements.
“Execute First Clamp Close” commands received by the QDC
module cause the module to immediately begin execution of the
profile using any non-zero entry in CPC09 (velocity) or CPC10
(pressure) as the profile setpoint. First close motion continues
until the clamp reaches the protective Start Low Pressure Close
Position (CPC61). At that time the QDC module either stops and
zeroes outputs (CPC03-B11 = 1), or begins execution of the Low
Pressure Close Profile (CPC03-B11 = 0) continuing to the
configured Mold Safe Position (CPC62)
“Execute First Clamp Open” commands received by the QDC
module cause the module to immediately begin execution of the
profile using any non-zero entry in OPC09 (velocity) or OPC10
(pressure) as the profile setpoint. First open motion continues until
the clamp reaches the protective Start Open Slow Position
(OPC61). At that time, the QDC module either stops and zeroes
outputs (OPC03-B11 = 1), or begins execution of the Open Slow
Profile (OPC03-B11 = 0) continuing to the configured Mold Fully
Open Position (OPC62)
“Execute Ejector Profile” commands received by the QDC module
cause the module to immediately begin execution of Ejector
Advance using the value in EPC09 (velocity) or EPC10 (pressure)
as the profile setpoint, and continuing to the configured Ejector
Fully Advanced Position (EPC59). If logically bridged to Ejector
Retract, the module then begins execution of Ejector Retract using
the value in EPC33 (velocity) or EPC34 (pressure) as the profile
setpoint, and continuing to the configured Ejector Fully Retracted
Position (EPC60)
