Extruder velocity control:
Enable or disable the control
length profile.
Control type: Select Photo/Mould
or Photo/Point control type only
with continuous extrusion. In
Photo/Mould mode, the control is
run by photocell digital input and
mould digital input.
In Photo/Point mode, the control, is run by photocell digital input and Point for control. With accumulator the control
is always made between end of filling and start injection. (see chapter 4.11.5 Velocity control)
Point for control: (the row is enabled when Photo/Point mode is selected) Point for the control (green). Yellow
point (on the left) is the point intercepted by the photocell. It is possible copy this value in point for control with the
confirm button. Yellow point (on the right) is the current point during the extrusion.
Minimum error: Minimum allowed error. (in point or in percentage)
Maximum error: Maximum allowed error. (in point or in percentage)
Maximum correction: Correction to be applied if the calculated error is greater of the maximum error. Maximum
correction applied at the velocity setpoint.
Correction type: Select from None to Maximum correction type. Correction - None: Output - None. Maximum
correction: use the Maximum correction value.
When the error is smaller of the Minimum error there is no correction.
When the error is inclusive between the Minimum error and the Maximum error the correction it is proportional
knowing the Maximum correction.
When the error is greater to the Maximum error the correction can be of two types:
Correction type = Maximum (The correction is the Maximum correction).
Correction type = Nothing (There is no correction). See Figure 15.
Delay time for photocell: Time before which the signal of the photocell has to be ignored. Only with continuous
extrusion.
Correction every n. cycles: Number of cycles after which make the correction.
Error number for warning: Number of consecutive errors to visualize a warning message.
