2–12 Command Word/Bit Descriptions
Publication 1771-6.5.88 – July 1997
Notes: 1. For [ ] engineering units, see page 3.
2. When using the Inject/Clamp/Eject mode, all pressure readings are system pressure at input 2, except where noted.
Word Description
CPC34 Segment 9 Pressure Setpoint [02]
if:
then the module:
you select Press/Pos profile execution controls clamp close pressure to this setpoint from the clamp position CPC32 until clamp
position reaches the larger of CPC35 or CPC61
CPC35 End of Segment 9 Position Setpoint [14]
Clamp Low Pressure Close Profile Setpoints
Word Description
CPC36 Reserved
CPC37 Segment 1 Pressure Setpoint [02]
The module controls clamp close pressure to this setpoint after starting the Clamp Low Pressure Close Profile until clamp position
reaches the larger of CPC38 or CPC62.
CPC38 End of Segment 1 Position Setpoint [14]
CPC39 Reserved
CPC40 Segment 2 Pressure Setpoint [02]
The module controls clamp close pressure to this setpoint from the clamp position CPC38 until clamp position reaches CPC62.
CPC41 -60 Open
Critical Process Setpoints
Word Description
CPC61 Start Clamp Low Pressure Close Position Setpoint [14]
The module uses this clamp position (overrun bit) as protection against running a Clamp Close Profile into the Mold Protection Zone.
if: then the module:
this position is reached while the module is immediately terminates the ongoing profile and checks state of CPC03-B11
executing any of the first three Clamp Close Profiles
RESET immediately begins the Clamp Low Pressure Close Profile
SET sets its outputs to zero
clamp position is less than or equal to this entry sets master status bit SYS03-B00
it reaches the Mold Protection Zone while executing sets alarm status bit SYS07-B06
one of the first three Clamp Close Profiles
CPC62 Mold Safe Position Setpoint (Mold Parting Line Touch) [14] This entry is the clamp position when the mold parting line mates . The
module uses this clamp position as the End of Low-Pressure-Close position setpoint.
if:
then the module:
this position is reached while module is executing immediately terminates the Clamp Low Pressure Close Profile and sets its
the Clamp Low Pressure Close Profile outputs to LPC33 - LPC40
clamp position is less than or equal to this entry sets master status bit SYS03-B01
CPC63 Tonnage Complete Pressure Setpoint [02]
if:
then the module:
clamp position is less than or equal to CPC62 compares real-time clamp pressure against this entry
clamp pressure equals or exceeds this entry when sets master status bit SYS03-B02
the clamp position is less than or equal to CPC62
CPC64 Open
