PARAMETERS
(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. (However, turning X14 ON is not necessary when Pr.128 = "50, 51, 60, 61, 110,
111, 120, 121".)
⋅ Enter the set point across inverter terminals 2-5 or into Pr. 133 and enter the measured value signal across inverter
terminals 4 and 5. At this time, set any of "20, 21, 120, 121" in Pr. 128.
⋅ When entering the externally calculated deviation signal, enter it across terminals 1 and 5. At this time, set any of
"10, 11, 110, 111" in Pr. 128.

selection
Turn ON X14 to perform PID control. Set 14 in any of Pr. 178 to Pr. 189.
X64
PID forward/
reverse action
switchover
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).
Set 64 in any of Pr. 178 to Pr. 189.
X72
PID integral value
reset
ON: Integral and differential values are
reset
OFF: Normal processing
Set 72 in any of Pr. 178 to Pr. 189.
