 Input/output signals
• Assigning the PID control valid (X14) signal 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 . (When the X14 signal is not assigned, PID control is enabled only by setting
Pr.128 ≠ "0".)

• 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.

Pr.189
When this signal is assigned to the input terminal, PID control is enabled
when this signal is ON.
The set point set in Pr.1460 to Pr.1466 can be selected by combining the
ON/OFF status of the signals.
PID control is switched between forward and reverse action without
changing parameters by turning ON this signal.
Integral and differential values can be reset by turning ON this signal.
Output when the measured value signal exceeds Pr.131 PID upper limit
(Pr.1143 Second PID upper limit).
Output when the measured value signal falls below Pr.132 PID lower limit
(Pr.1144 Second PID lower limit).
"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).
Turns ON during PID control.
When the PID calculation result is 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 not reflected to the output frequency (Pr.128
≥ "2000"), the PID signal turns ON during PID calculation regardless of the start
signal status.
Output when the absolute deviation value exceeds the limit value set in Pr.553
PID deviation limit (Pr.1145 Second PID deviation limit).
Set Pr.575 Output interruption detection time (Pr.1147 Second output
interruption detection time) ≠ "9999". This signal turns ON when the PID
output suspension function is activated.
