(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
(
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 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 .

PID control
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 .
X77
Pre-charge end
command Turn ON X77 to end the pre-charge
operation and start PID control.
Set 77 in any of Pr. 178 to Pr. 189 .
X78
Second pre-
charge end
command Turn ON X78 while RT is ON to end the
pre-charge operation and start PID
control.
Set 78 in any of Pr. 178 to Pr. 189 .

*1 The shaded area indicates the parameter initial value.
*2 When Pr. 128 = "40, 41, 50, 51, 60, 61, 140, 141" and the operation mode is not NET, input method is same as when Pr. 128 = "10, 11, 20, 21"
respectively. Input from BACnet communication is available when the operation mode is NET, Pr. 549 = "2" (BACnet), and RS-485 terminal
has the command source. Input from LonWorks or CC-Link communication is available when BACnet communication is inactive and the
operation mode is NET.
