2. When using the Inject/Clamp/Eject mode, all pressure readings are system pressure at input 2, except where noted.
Profile Tuning Constants
Word Description
INC49 Proportional Gain for Pressure Control [30]
INC50 Integral Gain for Pressure Control [27] or [28]
INC51 Derivative Gain for Pressure Control [26] or [21]
INC52 Proportional Gain for Velocity Control [28]

Profile Pressure Alarm Setpoint
Word Description
INC57 Profile High Ram (screw) Pressure Alarm Setpoint [01] The module compares real-time ram (screw) pressure against this entry
when executing the Injection Profile. The module sets alarm status bit SYS06-B00 when ram (screw) pressure equals or exceeds
this entry during the Injection Profile. A zero entry inhibits SYS06-B00.
INC58 Profile High Cavity Pressure Alarm Setpoint [04] The module compares real-time cavity pressure against this entry when executing
the Injection Profile. The module sets alarm status bit SYS06-B01 when cavity pressure equals or exceeds this entry during the
Injection Profile. A zero entry inhibits SYS06-B01.

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
