Special operation and speed control
(4) 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 drive unit terminal 2 or Pr.133 and enter the measured value to terminal 4.
REMARKS
When Pr.128 = "0" or X14 signal is OFF, normal drive unit 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.

"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).

When the X14 signal is not assigned, only the Pr.128 setting makes PID control valid.
The shaded area indicates the parameter initial value.
Refer to the CC-Link communication option (FR-A7NC E kit) instruction manual for the setting method from CC-Link communication.
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 144)
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 168 for setting)
