PKC
Word Description
PKC09 Output #1 Set-output Value during Profile [19]
PKC10 Output #2 Set-output Value during Profile [19]
PKC11 Output #3 Set-output Value during Profile [19]
PKC12 Output #4 Set-output Value during Profile [19]
PKC13–16 RFU
Output Ramp Rates
The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during the Pack Profile. The module
interprets a ramp rate of zero as a step function ramp (ramp disable).

PKC18 Output #2 Acceleration Ramp Rate during Profile [20]
PKC19 Output #3 Acceleration Ramp Rate during Profile [20]
PKC20 Output #4 Acceleration Ramp Rate during Profile [20]
PKC21-24 RFU
PKC25 Output #1 Deceleration Ramp Rate during Profile [20]
PKC26 Output #2 Deceleration Ramp Rate during Profile [20]
PKC27 Output #3 Deceleration Ramp Rate during Profile [20]
PKC28 Output #4 Deceleration Ramp Rate during Profile [20]
PKC29-40 RFU
Ram (Screw) Pressure Control Limits
Word Description
PKC41 Ram (Screw) Pressure Min Control Limit [01] Min controllable ram (screw) pressure attainable during any Ram Press/Time Pack
Profile. Module expects this ram (screw) pressure when setting its selected ram (screw ) pressure valve to the %-output in PKC43.
PKC42 Ram (Screw) Pressure Max Control Limit [01] Maxi controllable ram (screw) pressure attainable during any Ram Press/Time Pack
Profile. Module expects this ram (screw) pressure when setting its selected ram (screw) pressure valve to the %-output in PKC44.
PKC43 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 Pack Profile. The module expects a pressure equal to PKC41 when setting the
selected ram (screw) pressure valve to this %-output during profile execution. Ram Press/Time Pack Profile will be executed as a
reverse-acting algorithm if this entry is greater than PKC44.
PKC44 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 Pack Profile. The module expects a pressure equal to PKC42 when setting the
selected ram (screw) pressure valve to this %-output during profile execution. Ram Press/Time Pack Profile will be executed as a
reverse-acting algorithm if this entry is less than PKC43.
Cavity Pressure Control Limits
Word Description
PKC45 Cavity Pressure Minimum Control Limit [04] Minimum controllable cavity pressure attainable during any Cav Press/Time Pack Pro-
file . The module expects this cavity pressure when setting its selected cavity pressure valve to the %-output in PKC47.
PKC46 Cavity Pressure Maximum Control Limit [04] Maximum controllable cavity pressure attainable during any Cav Press/Time Pack
Profile . The module expects this cavity pressure when setting its selected cavity pressure valve to the %-output in PKC48.
PKC47 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 Pack Profile. The module expects a pressure equal to PKC45 when setting the selected
cavity pressure valve to this %-output during profile execution. The Cav Press/Time Pack Profile will be executed as a reverse-act-
ing algorithm if this entry is greater than PKC48.
PKC48 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 Pack Profile. The module expects a pressure equal to PKC46 when setting the selected
cavity pressure valve to this %-output during profile execution. The Cav Press/Time Pack Profile will be executed as a reverse-act-
ing algorithm if this entry is less than PKC47.
