Special operation and frequency control
(4) I/O signals and parameter setting
Set "20, 21" in
Pr. 128
to perform PID operation.
Set "14" in any of
Pr. 178 to Pr. 182 (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.
