HDC
End of Profile Set-output Values
When the module completes the Hold Profile and HPC03-B08 is SET, it:
•
sets its outputs to the following values
•
sets status bit SYS22-B06
•
uses ramp rates HDC17 - 32 when changing outputs to these values
Word Description
HDC33 Output #1 Set-output Value at End of Profile [19]
HDC34 Output #2 Set-output Value at End of Profile [19]
HDC35 Output #3 Set-output Value at End of Profile [19]
HDC36 Output #4 Set-output Value at End of Profile [19]
HDC37 Output #5 Set-output Value at End of Profile [19]
HDC38 Output #6 Set-output Value at End of Profile [19]
HDC39 Output #7 Set-output Value at End of Profile [19]
HDC40 Output #8 Set-output Value at End of Profile [19]
Ram (Screw) Pressure Control Limits
Word Description
HDC41 Ram (Screw) Pressure Minimum Control Limit [01] Minimum controllable ram (screw) pressure attainable during any Ram Press/
Time Hold Profile. The module expects this ram (screw) pressure when setting its selected ram (screw) pressure valve to the %-out-
put in HDC43.
HDC42 Ram (Screw) Pressure Maximum Control Limit [01] Maximum controllable ram (screw) pressure attainable during any Ram Press/
Time Hold Profile. The module expects this ram (screw) pressure when setting its selected ram (screw) pressure valve to the %-out-
put in HDC44.
HDC43 Selected Ram (Screw) Pressure Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the se-
lected pressure valve during any Ram Press/Time Hold Profile. The module expects a pressure equal to HDC41 when setting the
selected ram (screw) pressure valve to this %-output during profile execution. Ram Press/Time Hold Profile will be executed as a
reverse-acting algorithm if this entry is greater than HDC44.
HDC44 Selected Ram (Screw) Pressure Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the
selected pressure valve during any Ram Press/Time Hold Profile. The module expects a pressure equal to HDC42 when setting the
selected ram (screw) pressure valve to this %-output during profile execution. Ram Press/Time Hold Profile will be executed as a
reverse-acting algorithm if this entry is less than HDC43.
Cavity Pressure Control Limits
Word Description
HDC45 Cavity Pressure Minimum Control Limit [04] Minimum controllable cavity pressure attainable during any Cav Press/Time Hold Pro-
file. The module expects this cavity pressure when setting its selected cavity pressure valve to the %-output in HDC47.
HDC46 Cavity Pressure Maximum Control Limit [04] Maximum controllable cavity pressure attainable during any Cav Press/Time Hold Pro-
file . The module expects this cavity pressure when setting its selected cavity pressure valve to the %-output in HDC48.
HDC47 Selected Cavity Pressure Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected pres-
sure valve during any Cav Press/Time Hold Profile. The module expects a pressure equal to HDC45 when setting the selected
cavity pressure valve to this %-output during profile execution. The Cav Press/Time Hold Profile will be executed as a reverse-acting
algorithm if this entry is greater than HDC48.
HDC48 Selected Cavity Pressure Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected
pressure valve during any Cav Press/Time Hold Profile. The module expects a pressure equal to HDC46 when setting the selected
cavity pressure valve to this %-output during profile execution. The Cav Press/Time Hold Profile will be executed as a reverse-acting
algorithm if this entry is less than HDC47.
