I/O signals and parameter setting
Set "20, 21, 50, 51, 60 or 61" in Pr. 128 to perform PID operation.
Set "14" in any of Pr. 178 to Pr. 184 (input terminal function selection) to assign PID control selection signal (X14) to turn the
X14 signal ON.
When the X14 signal is not assigned, only the Pr. 128 setting makes PID control valid.
Enter the set point using the inverter terminal 2 or Pr. 133 and enter the measured value to terminal 4.
REMARKS
When Pr. 128 = "0" or X14 signal is OFF, normal inverter operation is performed without PID action.
Turning ON/OFF of bit of the terminal, to which X14 signal is assigned through network as RS-485 communication, enables
PID control.

When 100 or larger value is set in any of Pr.190 to Pr.192 (output terminal function selection), the terminal output has negative logic. (For details, Refer to page 145)
NOTE
Changing the terminal function using any of Pr. 178 to Pr. 184 and Pr. 190 to Pr. 192 may affect the other functions. Set
parameters after confirming the function of each terminal.
When the Pr. 267 setting was changed, check the voltage/current input switch setting. Different setting may cause a
fault, failure or malfunction. (Refer to page 176 for setting)

Output to indicate that the process value
signal exceeded the maximum value (Pr.

Output when the process value signal
falls below the minimum value (Pr. 132).
"Hi" is output to indicate that the output
indication of the parameter unit is
forward rotation (FWD) or "Low" to
indicate that it is reverse rotation (REV)
or stop (STOP).
Turns ON during PID control.
Common terminal for open collector
