v 1.4 — September 2015 Altanium Neo2
52 Changing PID Values
7.3.12 Changing PID Values
Sometimes it may be necessary to adjust the P, I or D values to better control the
temperatures of the heaters in the mold. Refer to Table 7-1 for a list of typical PID values. The
default settings are, “P” value of 20, “I” value of 4 and “D” value of 2. At least one zone must
be set to PID to be able to access the parameters.
NOTE:Neo2 must be in Advanced mode to change this setting. Refer to Section 4.2.1.
To change a P, I or D value:
1. On the Quick Set screen, touch the zone to adjust.
To select more than one zone, touch the additional zones and they will be selected.
2. Using the Parameter Scroll buttons, scroll to P, I or D.
3. Touch P, I or D and a numerical Key window appears.
4. Enter the number, and then touch Enter.
5. Touch OK.
7.4 ACTIVE REASONING Technology - The Definition
The science of applying microprocessor based control systems to automatic decision-
making. A control method directed at an active or continuous learning process which is
tolerant to faulty functions and incorrect operation by intentionally circumventing the
incorrect operation or failure.
7.4.1 Background
Active Reasoning is a term we coined to describe what Neo2 is doing during operation,
which is, actively reasoning. In 1990, we set out to develop the first intelligent hot runner
control system. In 1992 the first Active Reasoning Technology (ART) systems were shipped.
Throughout the years, we have improved and fine tuned ART, and today it is still the premier
heat control technology in the hot runner control industry.
7.4.2 What it does
Active Reasoning software combined with integrated hardware disseminates information
and makes better process decisions than any modular single input, single output controller
is capable of. The ability of all zones to interact with one another and understand the effects
of that interaction is paramount. Totally automatic control is one advantage. During Neo2
start up, the control looks at all zones individually, then looks at comparisons of all zones and
determines any interaction between them. It tests for any earth leakages individually and as
a whole. It then creates the necessary bake out and soft start routines to successfully and
evenly heat the mold.
