PID Basic Operation Setting Details
Code Description
AP.01 App Mode Set the code to 2 (Proc PID) to select functions for the process PID.
AP.16 PID Output Displays the existing output value of the PID controller. The unit, gain, and
scale that were set at AP. 42-44 are applied on the display.
AP.17 PID Ref Value Displays the existing value of the PID controller reference (setpoint) source.
The unit, gain, and scale that were set at AP. 42-44 are applied on the
display.
AP.18 PID Fdb Value Displays the existing value of the PID controller feedback source. The unit,
gain, and scale that were set at AP. 42-44 are applied on the display.
AP.19 PID Ref Set When AP.20 (PID control reference source) is set to 0 (Keypad), the reference
value can be entered. If the reference source is set to any other value, the
setting values for AP.19 are void.
AP.20 PID Ref Source Selects the source of the reference (setpoint) input for PID control. The
reference (setpoint) source cannot be the same source as the PID feedback
source (PID F/B Source).
Setting Function
0 Keypad Keypad
1 V1 -10-10V input voltage terminal
3 V2 I2 analog input terminal
[When analog voltage/current input switch (SW2) at the
terminal block is set to I (current), input 4-20mA current. If it
is set to V (voltage), input 0–10V voltage]
4 I2
5 Int. 485 RS-485 input terminal
7 FieldBu
s Communication command via a communication option card
9 UserSe
qLink
Link the common area with the user sequence output.
11 Pulse TI Pulse input terminal (0-32kHz Pulse input)
When using the 7-segment keypad, the PID reference setting can be
displayed at AP.17. When using the LCD keypad, the PID reference setting
can be viewed in the Monitor Mode by assigning config mode parameters
(CNF).21-23, set to 17 (PID Ref Value).
AP.21 PID F/B Source Selects the source of the feedback input to the PID control. The same list of
sources (above) can be selected, except the keypad input (Keypad-1 and
Keypad-2). Also, the feedback source cannot be the same as the reference
(setpoint) source. When using the LCD keypad, the feedback can be viewed
in the Monitor Mode by assigning config mode parameters (CNF).21-23, set
to 18 (PID Fbk Value).
