End of Profile Set-output Values
When module completes Plastication Profile and PPC03-B08 is set, it:
•
sets status bit SYS22-B08
•
uses ramp rates PLC17-20 and PLC25-28 when changing outputs
•
sets its outputs to the following values
Word Description
PLC33 Output #1 Set-output Value at End of Profile [19]
PLC34 Output #2 Set-output Value at End of Profile [19]
PLC35 Output #3 Set-output Value at End of Profile [19]
PLC36 Output #4 Set-output Value at End of Profile [19]
PLC37-40 RFU
Pressure Control Limits
Word Description
PLC41 Pressure Minimum Control Limit [01] Minimum controllable ram (screw) pressure attainable during any Press/Pos or Press/Time
Plastication Profile. The module expects this ram (screw) pressure when setting its selected valve to the %-output in PLC43.
PLC42 Pressure Maximum Control Limit [01] Maximum controllable ram (screw) pressure attainable during any Press/Pos or Press/Time
Plastication Profile. The module expects this ram (screw) pressure when setting its selected valve to the %-output in PLC44.
PLC43 Selected Pressure Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected pressure
valve during any Press/Pos or Press/Time Plastication Profile. The module expects a pressure equal to PLC41 when setting the
selected pressure valve to this %-output during profile execution. The profile will be executed as a reverse-acting algorithm if this
entry is greater than PLC44.
PLC44 Selected Pressure Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected pressure
valve during any Press/Position or Press/Time Plastication Profile. The module expects a pressure equal to PLC42 when setting the
selected pressure valve to this %-output during profile execution. The profile will be executed as a reverse-acting algorithm if this
entry is less than PLC43.
RPM Control Limits
Word Description
PLC45 RPM Minimum Control Limit [25] Minimum controllable RPM attainable during any RPM/Pos or RPM/Time Plastication Profile. The
module expects this RPM when setting its selected valve to the %-output in PLC47.
PLC46 RPM Maximum Control Limit [25] Maximum controllable RPM attainable during any RPM/Pos or RPM/Time Plastication Profile. The
module expects this RPM when setting its selected valve to the %-output in PLC48.
PLC47 Selected RPM Valve Output for Minimum [19] 0% CV output (%) that the module uses to drive the selected RPM valve during any
Press/Position or Press/Time Plastication Profile. The module expects an RPM equal to PLC45 when setting the selected RPM
valve to this %-output during profile execution. The profile will be executed as reverse-acting if this entry is greater than PLC48.
PLC48 Selected RPM Valve Output for Maximum [19] 100% CV output (%) that the module uses to drive the selected RPM valve during
any Press/Position or Press/Time Plastication Profile. The module expects an RPM equal to PLC46 when setting the selected RPM
valve to this %-output during profile execution. The profile will be executed as reverse-acting if this entry is less than PLC47.
