Plastication Profile Offsets
Word Description
PPC51 Profile RPM Offset [01] If you select RPM/Pos or RPM/Time profile execution, the module applies this entry (after reading the sign
bit) to each RPM profile setpoint.
PPC52 Profile Pressure Offset [01] If you select Press/Pos or Press/Time profile execution, the module applies this entry (after reading the
sign bit) to each pressure profile setpoint.
PPC53 - 60 Open
Critical Process Setpoints
These two entries let the module establish the 100% shot size position,
defined at ram (screw) position of MCC13 + PPC61 + PPC62. The
module terminates all Plastication Profiles at 100% shot size position.
Word Description
PPC61 Cushion Size [12] Informs the module of the nominal length of molten plastic that should remain in the barrel at conclusion of the
Hold Profile. The module uses it only to calculate the 100% shot size position.
PPC62 Shot Size [17] Informs the module of the nominal length of molten plastic that should be drawn during the Plastication Profile. The
module uses it only to calculate the 100% shot size position.
PPC63 - 64 Open
Bit-mapped Control Words
Word Description
PRC01 Block ID = 00001101 (Low byte). High byte reserved for the module. Do not use.
PRC02 - 04 Open
Movement Length
Word Description
PRC05 Incremental Movement Length [17] When the module starts the Pre-decompression Movement, it adds this entry to the current ram
(screw) position to establish the End of Pre-decompression position. The module uses the End of pre-decompression position as
the termination point of all pre-decompression movements.
PRC06 - 07 Open
Watchdog Timer
Word Description
PRC08 Movement Watchdog Timer Preset [21]
When the module starts the Pre-decompression Movement, it:
S
starts an internal Movement Watchdog timer
S
stops this timer and resets its accumulated value to zero (after reporting total execution time in HPS59) when it completes the
movement
S
sets master status bit SYS04-B07 when the accumulated value of this timer equals or exceeds this entry.
A zero entry inhibits SYS04-B07.
Movement Set-output Values
When the module starts the Pre-decompression Movement, it:
• sets its outputs to the values listed below
• uses ramp rates PRC17 - PRC32 to ramp outputs
PRC – Pre-decompression
