Output Ramp Rates
The module uses the following ramp rates when moving its outputs
from setpoint to setpoint during the Injection Profile. The module
interprets a ramp rate of zero as a step function ramp (ramp disable).
Word Description
INC17 Output #1 Acceleration Ramp Rate during Profile [20]
INC18 Output #2 Acceleration Ramp Rate during Profile [20]
INC19 Output #3 Acceleration Ramp Rate during Profile [20]
INC20 Output #4 Acceleration Ramp Rate during Profile [20]
INC21-24 RFU
INC25 Output #1 Deceleration Ramp Rate during Profile [20]
INC26 Output #2 Deceleration Ramp Rate during Profile [20]
INC27 Output #3 Deceleration Ramp Rate during Profile [20]
INC28 Output #4 Deceleration Ramp Rate during Profile [20]
INC29-32 RFU
End of Profile Set-output Values
When module completes the Injection Profile and IPC02-B08 is SET, it:
•
sets status bit SYS02-B04
•
uses ramp rates INC17-20 and INC25-28 when changing outputs
•
sets its outputs to the following values
Word Description
INC33 Output #1 Set-output Value at End of Profile [19]
INC34 Output #2 Set-output Value at End of Profile [19]
INC35 Output #3 Set-output Value at End of Profile [19]
INC36 Output #4 Set-output Value at End of Profile [19]
INC37-40 RFU
Pressure Control Limits
Word Description
INC41 Pressure Minimum Control Limit [01] Minimum controllable ram (screw) pressure attainable during any Press/Pos or Press/Time
Injection Profile. The module expects this ram (screw) pressure when setting its selected pressure valve to the %-output in INC43.
INC42 Pressure Maximum Control Limit [01] Maximum controllable ram (screw) pressure attainable during any Press/Pos or Press/Time
Injection Profile. The module expects this ram (screw) pressure when setting its selected pressure valve to the %-output in INC44.
INC43 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 Injection Profile. The module expects a pressure equal to INC41 when setting the se-
lected pressure valve to this %-output during profile execution. The Press/Pos or Press/Time Injection Profile will be executed as a
reverse-acting algorithm if this entry is greater than INC44.
INC44 Selected Pressure Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected pressure
valve during any Press/Pos or Press/Time Injection Profile. The module expects a pressure equal to INC42 when setting the se-
lected pressure valve to this %-output during profile execution. The Press/Pos or Press/Time Injection Profile will be executed as a
reverse-acting algorithm if this entry is less than INC43.
