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.

Injection Transition Parameters

Injection transition-to-pack or hold occurs when the four words in
this table go to a state of non-zero. If you want the module to ignore
one or more parameters when monitoring the Injection Profile for
transition, enter zero for that parameter.

Word

Description

IPC60

Time Limit for Transition [21] The module immediately terminates the Injection Profile and begins the Pack(Hold) Profile if the total
Injection Profile execution time equals or exceeds the non-zero entry in this word. The module ignores this parameter if zero.

IPC61

Ram (Screw) Position for Transition [12] The module immediately terminates the Injection Profile and begins the Pack(Hold) Profile
if real-time ram (screw) position is less than or equal to the non-zero entry in this word. The module ignores this parameter if zero.

IPC62

Ram (Screw) Pressure for Transition [01] If real-time ram (screw) position is less than or equal to any non-zero entry in IPC64, the
module immediately terminates the Injection Profile and begins the Pack(Hold) Profile if real-time ram (screw) pressure equals or
exceeds this non-zero entry. The module ignores this parameter if zero.

IPC63

Cavity Pressure for Transition [04] If real-time ram (screw) position is less than or equal to any non-zero entry in IPC64, the module
immediately terminates the Injection Profile and begins the Pack(Hold) Profile if real-time cavity pressure equals or exceeds this
non-zero entry. The module ignores this setpoint if zero.

Pressure Transition Inhibit

Word

Description

IPC64

Ram (Screw) Position for Pressure Transition Inhibit [12] A non-zero entry forces the module to ignore any non-zero IPC62 and
IPC63 until ram (screw) position is equal to or less than this entry. A zero entry forces the module to use any non-zero entry in
IPC62 and IPC63 during the entire Injection Profile.

The The module will not accept or process the Jog Configuration
Command Block unless it has a valid MCC installed.

Jog Alarm Setpoints

Word

Description

JGC05

Screw Rotate Jog RPM Alarm Setpoint [25] The module compares real-time screw RPM against this entry when responding to
command bit DYC01-B09 = 1. The module sets alarm status bit SYS05-B08 when screw RPM equals or exceeds this entry during a
Screw Rotate Jog. A zero entry inhibits SYS05-B08.

JGC06

Ram (Screw) Jog Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry when re-
sponding to command bit DYC01-B10 = 1 or DYC01-B11 = 1. The module sets alarm status bit SYS05-B09 when ram (screw) pres-
sure equals or exceeds this entry during a Ram (Screw) Jog. A zero entry inhibits SYS05-B09.

JGC07

Clamp Jog Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when responding to
command bit DYC01-B12 = 1 or DYC01-B13 = 1. The module sets alarm status bit SYS05-B10 when clamp pressure equals or
exceeds this entry during a Clamp Jog. A zero entry inhibits SYS05-B10.

JGC08

Ejector Jog Pressure Alarm Setpoint [03] the module compares real-time ejector pressure against this entry when responding to
command bit DYC01-B14 = 1 or DYC01-B15 = 1. The module sets alarm status bit SYS05-B11 when ejector pressure equals or
exceeds this entry during an Ejector Jog. A zero entry inhibits SYS05-B11.
