Input/Output Signals - Mitsubishi Electric FR-F800 Instruction Manual

(A) Application parameters
Input/output signals
• Assigning the PID control valid terminal signal (X14) to the input terminal by Pr.178 to Pr.189 (input terminal function
selection) enables PID control to be performed only when the X14 signal is turned ON. When the X14 signal is OFF,
regular inverter running is performed without PID action.

NOTE
• Changing the terminal functions with Pr.178 to Pr.189 and Pr.190 to Pr.196 may affect other functions. Set parameters after
confirming the function of each terminal.

14
When the signal is assigned to the input terminal, PID control is enabled
when the signal is ON.
80
38
The set point set in Pr.1460 to Pr.1466 can be selected by combining the
39
ON/OFF status of the signals.
40
64
PID control is switched between forward and reverse action without
changing parameters by turning ON the signal.
79
72
Integral and differential values can be reset by turning the signal ON.

15 115
Output when the measured value signal exceeds Pr.131 PID upper limit
(Pr.1143 Second PID upper limit).
201 301
14 114
Output when the measured value signal exceeds Pr.132 PID lower limit
(Pr.1144 Second PID lower limit).
200 300
16 116
"Hi" is output when the output display of the parameter unit is forward
rotation (FWD), and "Low" is output when the display is reverse rotation
(REV) and stop (STOP).
202 302
Turns ON during PID control.
47 147
When the PID calculation result is not reflected to the output frequency
(Pr.128 < "2000"), the PID signal turns OFF at turn OFF of the start signal.
When the PID calculation result is reflected to the output frequency
203 303
(Pr.128  "2000"), the PID signal turns ON regardless of the start signal
status during PID calculation.
70 170
Set Pr.575 Output interruption detection time (Pr.1147 Second output
interruption detection time) "9999". This signal turns ON when the
204 304
PID output suspension function is activated.
