Description
Inject
pressure limit
Use Inject
Pressure Limit
PID
When this option is selected, the pressure limit is regulated
(PID), otherwise it will be controlled.
P
The proportional part for the injection regulator is adjusted
here.
I The integral part for the injection regulator is adjusted here.
D
The di󰀨erential part for the injection regulator is adjusted
here.
Pressure limit
controller
Use Inject
Pressure Limit
Velocity
When this option is selected, the injection is regulated (PID),
otherwise it will be controlled.
P
The proportional part for the pressure limit controller is
adjusted here.
I
The integral part for the pressure limit controller is adjusted
here.
D
The di󰀨erential part for the pressure limit controller is adjusted
here.
Hold
Use hold PID
When this option is selected, the hold pressure is regulated
(PID), otherwise it will be controlled.
P
The proportional part for the hold pressure controller is
adjusted here.
I
The integral part for the hold pressure controller is adjusted
here.
D
The di󰀨erential part for the hold pressure controller is
adjusted here.
Backpressure
Use
backpressure
PID
When this option is selected, the backpressure at
plasticizing is regulated (PID), otherwise it will be controlled.
Precondition for control: Oil backow at linear screw
movement in backward direction must be throttled by an
electromagnetically activated proportional valve.
P
The proportional part for the back pressure at plasticizing is
adjusted here.
I
The integral part for the back pressure at plasticizing is
adjusted here.
D
The di󰀨erential part for the back pressure at plasticizing is
adjusted here.
CAUTION
Modifying PID values can cause damage to the injection unit that is not
covered under warranty.
Record the original values before making changes.
Change values one at a time and in small steps.
For P, the larger the value, the greater the e󰀨ect.
For I, the smaller the value, the greater the e󰀨ect.
CAUTION
