Description
8
Pulse
TI Pulse input terminal (0-32 kHz Pulse input)
10
V3
V3 analog input terminal of Extended IO option card.
11
I3
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.
PID-11
PID Ref Set
Enter a reference value (setpoint) if the PID Ref 1 Src (PID-10) is set to ‘0
(Keypad)’.
PID-12
PID Ref1AuxSrc
Selects an auxiliary reference source (a second feedback source) if used with
the PID control. If an auxiliary source is selected, the reference is determined
using the input value at the Ref 1 source (set at PID-10) and the value set at
PID-13 PID Ref1AuxMod.

V1
-10-10 V input voltage terminal
3
V2
I2 analog input terminal
4
I2
If the analog voltage/current input terminal selection switch
(SW4) at the terminal block is set to I (current), input 0-20
mA current. If it is set to V (voltage), input 0–10 V
6
Pulse
TI Pulse input terminal (0-32 kHz Pulse input)
7
Int. 485
RS-485 input terminal
8
FieldBus
Communication command via a communication option card
12
V3
V3 analog input terminal of Extended IO option card.
13
I3
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.
PID-13
PID Ref1AuxMod
PID-13 (PID Ref1AuxMod) provides formulas to calculate the reference 1
value. If PID-12 (PID Ref1AuxSrc) 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).

Square Root(M+A)
M= Value by the PID Ref 1 source set at PID-10
G= Gain value set at PID-14
A= Value input by the Ref1 Aux Src 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 the source of the feedback input for PID control. PID-20 (feedback)
cannot be set to the same source as PID-10 (PID Ref1 source) .
