B. Supplementary on PID Control Block Diagram
A PID control block diagram is
Target
Feedback
signal
Note : 1. A target signal may come from digital operator, PS-485 port or multi-
function analog input terminal-AUX setting. (upon Sn-05 setting).
2. The detected signal can be input either from terminal VIN (Sn-24=0,
voltage command 0~10V) or from terminal AIN (Sn-24=1, current
command 4~20mA).
3. If the target signal is from the terminal AUX, please use the wiring as
below: (Sn-05=01, Sn-29=09)
4. Please refer to page 42, 43 for more details about PID use.
