Parameter
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. (When Pr. 128 = "10, 11, 20, 21, 40 or 41".)
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, 21, 120 or 121" in Pr. 128.
When entering the calculated deviation signal of an external (PID) controller, enter it across ter-
minals 1-5. At this time, set "10, 11, 110, 111" in Pr. 128.

Description
Turn ON X14 to perform PID
control.
By turning ON X64, forward action
can be selected for PID reverse
action (Pr. 128 = 10, 20, 110, 120),
and reverse action for forward
action (Pr. 128 = 11, 21, 111, 121).
ON: Integral and differential
values are reset
OFF: Normal processing
Turn ON X77 to end the pre-
charge operation and start PID
control.
Turn ON X78 while RT is ON to
end the pre-charge operation and
start PID control.
Enter the set point for PID control. Pr. 128 = 20, 21, 120, 121
0–5V................ 0–100%
0–10V.............. 0–100%
0/4–20mA........ 0–100%
Set the set value (Pr. 133) from
the operation panel or parameter
unit.
Input the deviation signal
calculated externally.
−5V–+5V............... −100%–+100%
−10V–+10V .......... −100%–+100%
Input the signal from the detector
(measured value signal).
