) 0~30,000(%)
The proportion for
magnifying/minifying the error
between SV and PV.
Integration gain (K
I
) 0~30,000(%)
The proportion for
magnifying/minifying the integral
value (The accumulated error). For
control mode K0~K2, K5.

The proportion for
magnifying/minifying the derivative
value (The rate of change of the
process error). For control mode
K0~K2, K5.

E = the error between SV and PV.
If S
3
+5 is set as 5, when E is
between -5 and 5, E will be 0.
When S
3
+5 = K0, the function will
not be enabled.

Ex: if S

+6 is set as 1,000, MV will
be 1,000 when it exceeds 1,000.
S
3
+6 has to be bigger or equal to
S
