HPC01 Block ID = 00001100 (Low byte). High byte reserved for the module. Do not use.
HPC02 RFU
HPC03 Configuration Selections
Profile Algorithm Selections
B00 = 0 Ram Press/Time selected for Pack Profile
= 1 Cav Press/Time selected for Pack Profile
B01 RFU
B02 = 0 Ram Press/Time selected for Hold Profile
= 1 Cav Press/Time selected for Hold Profile
B03-07 RFU
B08 Hold/Pre-decompression Logical Bridge Selection
= 0 Start Pre-decompression Movement at End of Hold Profile
= 1 Stop and Set-output at End of Hold Profile
The module checks the state of this pause bit upon completion of Hold Profile to determine what further action to take:
if:
then the module:
SET sets its outputs to HDC33–36
RESET, SYS15-B12 = 1, immediately begins the Pre-decompression Movement
and PRC05 > 00000
RESET, SYS15-B12 = 1,
reacts as if it had just completed the Pre-decompression Movement and continues
and PRC05 = 00000 operation based on the state of HPC03-B09
RESET, SYS15-B12 = 0, reacts as if it had just received an F-to-T transition of DYC02-B08
and HPC03-B09 = 0
RESET, SYS15-B12 = 0,
sets its outputs to zero and latches SYS13-B08
and HPC03-B09 = 1
B09 Pre-decompression/Plastication Logical Bridge Selection
= 0 Start Plastication Profile at End of Pre-decompression Movement
= 1 Stop and Set-output at End of Pre-decompression Movement
The module checks the state of this pause bit after completing the Pre-decompression Movement to determine what
further action to take:
if:
then the module:
SET sets its outputs to PRC33–36
RESET and SYS15-B14 = 1 immediately begins the Plastication Profile
RESET and SYS15-B14 = 0 sets its outputs to zero and latches SYS13-B09
B10-11 RFU
Profile Offset Sign Selection
B12 = 0 Pack Cav Press Profile Offset is Positive
= 1 Pack Cav Press Profile Offset is Negative
B13 = 0 Pack Ram Press Profile Offset is Positive
= 1 Pack Ram Press Profile Offset is Negative
B14 = 0 Hold Cav Press Profile Offset is Positive
= 1 Hold Cav Press Profile Offset is Negative
B15 = 0 Hold Ram Press Profile Offset is Positive
= 1 Hold Ram Press Profile Offset is Negative
HPC04 Configuration Selections
Open/Closed Loop Selection
B00 = 0 Ram Press/Time Pack Profiles Closed Loop
= 1 Ram Press/Time Pack Profiles Open Loop
B01 = 0 Cav Press/Time Pack Profiles Closed Loop
= 1 Cav Press/Time Pack Profiles Open Loop
B02 = 0 Ram Press/Time Hold Profiles Closed Loop
= 1 Ram Press/Time Hold Profiles Open Loop
B03 = 0 Cav Press/Time Hold Profiles Closed Loop
= 1 Cav Press/Time Hold Profiles Open Loop
