Functions
Target Value Selection
•The target value depends on the terminal selected in frequency reference A001 other than that in
A076.
You cannot set analog inputs O and OI to both target and feedback values simultaneously. Do not
connect the signal lines for inputs O and OI simultaneously.
Feedback Selection
•Select a terminal for feedback signals in A076.
The setting of O/OI terminal selection A005 is disabled when the control terminal block (terminal)
01 is set in A001.
PID Feedback Value Monitor
•You can monitor the PID feedback value in d004.
•The monitor value is displayed as the multiplied value of the PID scale (A075).
Monitor display = Feedback value (%) × A075 setting
Excessive Deviation/Output
•You can set the PID deviation excessive level (C044) during PID control. If the PID deviation
reaches the PID deviation excessive level (C044), the multi-function output terminal is turned on.
•Allocate 04 (OD) to any of the multi-function output terminal 11 selection (C021) or relay output
(AL2, AL1) function selection (C026)..
•C044 can be set from 0 to 100. Setting corresponds to the range of 0 to the maximum target value.
