This section describes the commands that are used to read and write fuzzy
constants.
This section covers the commands that are used to set fuzzy constants: the
fuzzy strength, fuzzy scale 1, and fuzzy scale 2.
Designate the point and memory bank to set the fuzzy constant. Fuzzy strength
cannot be set automatically. Autotuning PID constants automatically sets the
values of fuzzy scales 1 and 2. If the PID constants have been manually set, the
values of fuzzy scales 1 and 2 automatically changes according to the PID
constants. It is possible to change the values of fuzzy scales 1 and 2 manually
after the PID constants are set.
The header code varies with the fuzzy constant to be set. These commands can-
not be used while autotuning is being executed.
Designate a fuzzy strength value between 0000 and 0099 in increments of 1%. If
0000 is designate, the Temperature Controller will control the temperature using
only PID with feed-forward circuitry.
j Bank Point 0
Data code
Designate a fuzzy scale 1 value between 0002 and 9999 in increments of 0.1°C
or 0.1°F.
k Bank Point 0
Data code
Designate a fuzzy scale 2 value between 0020 and 9999 in increments of
0.01°C/s or 0.01°F/s.
I Bank Point 0
Data code
The following command is used to set the Temperature Controller to a fuzzy
strength of 25% in memory bank 3 of point 2 in unit 1.
j 3 2 0
0 Fuzzy strength
0000 to 0099
In increments of
1%
0 Fuzzy scale 1
0002 to 9999
The position of the imaginary decimal
(in increments of 0.1°C/°F)
0 Fuzzy scale 2
0020 to 9999
The position of the imaginary decimal
(in increments of 0.01°C/s or 0.01°F/s)
0 0 0 2
