Velocity Control Limits

Word

Description

INC45

Velocity Minimum Control Limit [06] Minimum controllable ram (screw) velocity attainable during any Vel/Pos Injection Profile. The
module expects this ram (screw) velocity when setting its selected velocity valve to the %-output in INC47.

INC46

Velocity Maximum Control Limit [06] Maximum controllable ram (screw) velocity attainable during any Vel/Pos Injection Profile. The
module expects this ram (screw) velocity when setting its selected velocity valve to the %-output in INC48.

INC47

Selected Velocity Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected velocity valve
during any Vel/Pos or LimVel/Pos Injection Profile. The module expects a velocity equal to INC45 when setting the selected velocity
valve to this %-output during profile execution. The Vel/Pos or LimVel/Pos Injection Profile will be executed as a reverse-acting
algorithm if this entry is greater than INC48.

INC48

Selected Velocity Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected velocity
valve during any Vel/Pos or LimVel/Pos Injection Profile. The module expects a velocity equal to INC46 when setting the selected
velocity valve to this %-output during profile execution. The Vel/Pos or LimVel/Pos Injection Profile will be executed as a reverse-
acting algorithm if this entry is less than INC47.

Profile Tuning Constants

Word

Description

INC49

Proportional Gain for Pressure Control [30]

INC50

Integral Gain for Pressure Control [27] or [28]

INC51

Derivative Gain for Pressure Control [26] or [21]

INC52

Proportional Gain for Velocity Control [28]

INC53

Feed Forward Gain for Velocity Control [30]

INC54 - 56

RFU

Profile Pressure Alarm Setpoint

Word

Description

INC57

Profile High Ram (screw) Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry
when executing the Injection Profile. The module sets alarm status bit SYS06-B00 when ram (screw) pressure equals or exceeds
this entry during the Injection Profile. A zero entry inhibits SYS06-B00.

INC58

Profile High Cavity Pressure Alarm Setpoint [04] The module compares real-time cavity pressure against this entry when executing
the Injection Profile. The module sets alarm status bit SYS06-B01 when cavity pressure equals or exceeds this entry during the
Injection Profile. A zero entry inhibits SYS06-B01.

INC59 - 60

RFU

Set-outputs During Suspended Injection

Word

Description

INC61

Output #1 Set-output value during suspended injection [19] During suspension, IPC02:B11, B12 determine the status of outputs.

INC62

Output #2 Set-output value during suspended injection [19] During suspension, IPC02:B11, B12 determine the status of outputs.

INC63

Output #3 Set-output value during suspended injection [19] During suspension, IPC02:B11, B12 determine the status of outputs.

INC64

Output #4 Set-output value during suspended injection [19] During suspension, IPC02:B11, B12 determine the status of outputs.
