Code Description
Output
11 EPID1 Fdb
Val External PID 1 feedback value
12 V3 V3 analog input terminal of Extension IO option
When the analog voltage/current input terminal
selection switch (SW2) at the terminal block is set to
I3 (current), input 0-20 mA current. If it is set to V3
(voltage), input 0–10 V.
13 I3
PID-13 PID Ref1
AuxMod
PID-13 (PID Ref1) provides formulas to calculate the reference 1 value. If PID-
12 (PID RefAuxSrc) is set to any other value than ‘None,’ the final reference 1
value is calculated using the input value at the source (set at PID-10) and the
input value set at PID-12).
Setting

1 M*(G*A)
2 M/(G*A)
3 M+(M*(G*A))
4 M+G*2*(A-50)
5 M*(G*2*(A-50))

9 M^2+A^2
10 MAX(M,A)

12 (M+A)/2
13 Square Root(M+A)
M= Value by the source set at PID-10
G= Gain value set at PID-14
A= Value input by the source set at PID-12
PID-14 PID Ref1 Aux
G
Gain value for the formulas provided by PID-13.
PID-20 PID Fdb Src
Selects feedback input for PID control. If the V1 terminal is set as the PID
feedback source (PID F/B Source), the V1 terminal cannot be set as the PID
reference source (PID Ref Source). To set V1 as a feedback source, change the
reference source.
