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.
 PID automatic switchover control (Pr.127)
• The system can be started up more quickly by starting up without PID control activated.

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

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 falls below 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 (Pr.128 ≥
203 303
"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 PID
output suspension function is activated.
