Word Bit Description
IPC01 Block ID = 00001001 (Low byte). High byte reserved for the module. Do not use.
IPC02 Co-injection Parameters P 2
B00-07 RFU
B08 Selection bit IPC02:B08 for QI(A) IPCB02:B08 for QI(B)
Select whether to inhibit or allow bridging from injection to pack
0 = bridge from injection to pack
1 = disabled bridging. Your logic must continue the process.
B09 RFU
B10 Command bit IPC02:B10 for QI(A) IPCB02:B10 for QI(B)
Upon reaching screw position (in IPC56), QI(A) suspends its injection profile until B’s screw position (in ICPB08) is
reached. Then QI(A) resumes injection.
0 = command inhibited
1 = enables the command
IPC56 and IPCB08 must have valid non-zero values for this command.
During suspension, IPC02:B11, B12 determine the status of outputs.
B11, B12 Selection bits IPC02:B11, B12 for QI(A) IPCB02:B11, B12 for QI(B)
Select the module’s output mode during suspended injection. When using closed-loop pressure or velocity control of
the injection valve, the other three outputs are set-outputs in INC61–64.
B12 B11
0
0 = control all four outputs with set-outputs stored in INC61–64
0 1 = control injection valve with pressure setpoint in IPC55
1 0 = control injection valve with velocity setpoint in IPC54
1 1 = error condition
B13-15 RFU
IPC03 Configuration Selections
B00-01 Profile Algorithm Selection
B01 B00
0 0 Vel/Pos selected
0 1 Vel/Pos (pressure limited) selected
1 0 Press/Pos selected
1 1 Press/Time selected
B02-11 RFU
Profile Offset Sign Selection
B12 = 0 Injection Velocity Profile Offset is Positive
= 1 Injection Velocity Profile Offset is Negative
B13 = 0 Injection Pressure Profile Offset is Positive
= 1 Injection Pressure Profile Offset is Negative
Velocity Units Selection
B14 = 0 Velocity Parameters in Percent Velocity
= 1 Velocity Parameters in in.(mm)/s
if:
then the module:
RESET returns all segment velocity actuals (and assumes all velocity setpoints) in percent velocity where INC46
represents 100% velocity
SET returns all velocity actuals (and assumes all velocity setpoints) in in.(mm)/s
B15 RFU
IPC04 Configuration Selections
Open/Closed Loop Selection
B00 = 0 Vel/Pos Injection Profiles Closed Loop
= 1 Vel/Pos Injection Profiles Open Loop
B01 = 0 Vel/Pos (limited) Injection Profiles Closed Loop
= 1 Vel/Pos (limited) Injection Profiles Open Loop
B02 = 0 Press/Pos Injection Profiles Closed Loop
= 1 Press/Pos Injection Profiles Open Loop
B03 = 0 Press/Time Injection Profiles Closed Loop
= 1 Press/Time Injection Profiles Open Loop
