Select MODIF to modify one of these 5 parameters
and validate. Possible choices are displayed above
the arrows as far as the language and the unit for
screw position. Enter the required value with the
keyboard for time, date and password.
1. Unit in (%):
This unit is related to the injected volume of
material. 0% is set at injection start and 100%
is reached when the screw is empty. This unit is
directly linked to the injection shot size of the
machine. If a sequence programmed on a machine
with an injection unit A is loaded on the controller
used on a machine with a different injection unit
B, the new shot size must be set so that the values
programmed in % remain valid.
2. Unit in (mm):
Values programmed using this unit depend on
the screw position not on the volume of injected
material. This unit does not rely on the shot size
but on the calibration of the screw position
signal received by the controller. A programmed
sequence using this unit relates to the machine
and any file using this unit should be modified to
be used on a different machine.
3. Unit in (cm3):
This unit depends on the calibration of the screw
position and on the injected volume of material. It
is independent from the shot size. A programmed
sequence using this unit can be used on a
different machine if the controller has been re-
calibrated for the new machine.
Advantages and disadvantages are on the
compatibility of saved sequence files loaded on
different injection units:
• Programs in % Re-calibration is not
required.
• Programs in mm: Re-calibration is required.
New calculation of
command values.
• Programs in cm
3
Re-calibration is required.
CAUTION: The programmed sequence is lost if the
unit for screw position is changed.
CAUTION: Check the programmed sequence after
changing the unit.
