Special operation and frequency control
(4) I/O signals and parameter setting
⋅ Turn on the X14 signal to perform PID control. When this signal is off, PID action is not performed and normal
inverter operation is performed. (Note that it is not necessary to turn on X14 signal when performing PID control
with using LONWORKS or CC-Link communication. )
⋅ Enter the set point across inverter terminals 2-5 or into Pr. 133 and enter the measured value signal across inverter
terminals 4-5. At this time, set "20" or "21" in Pr. 128.
⋅ When entering the externally calculated deviation signal, enter it across terminals 1-5. At this time, set "10" or "11"
in Pr. 128.

*3 When 100 or larger value is set in any of Pr. 190 to Pr. 196 (output terminal function selection), the terminal output has negative logic. (Refer to
page 230 for details)
CAUTION
⋅ Changing the terminal function using any of Pr. 178 to Pr. 189, 190 to Pr. 196 may affect the other functions. Please make setting
after confirming the function of each terminal.
⋅ When the Pr. 73 and Pr. 267 settings were changed, check the voltage/current input switch setting. Different setting may cause a
fault, failure or malfunction. (Refer to page 275 for setting.)
