Special operation
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.
NOTES
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.
