PID control (Pr. 128 to Pr. 134)
(4) I/O signals
To start PID control, turn on the X14 signal. When this signal is off, normal inverter operation is performed without
the PID action being done.

When entering the externally calculated deviation signal, enter it across terminals 1-5. At this time, set "10" or "11"
in Pr. 128.
The set point is given to across inverter terminals 2-5 or set in Pr.133. The measured value signal is input to
across inverter terminals 1-5. At this time, set "30" or "31" in Pr.128.
Analog input voltage range of the measured value differs according to the year and month when the inverter was
manufactured
•In and before June 2003 ... 0V to 10V (input of -10V to 0V are regarded as 0V)
•In and after July 2003........ -10V to 10V
Check the rating plate for the month when the inverter was manufactured. (Refer to page 220.)

Description
Set any of 10, 11, 30 and 31 in Pr. 128.

Description
When 10 or 11 is set in Pr. 128,
terminal 1 gives the deviation input signal
independently of the Pr. 868 setting.
When 30 or 31 is set in Pr. 128,
terminal 1 gives the measured value input signal
independently of the Pr. 868 setting.
