NOTE
Changing the terminal function using any of Pr. 178 to Pr. 182, Pr. 190 and Pr. 192 may affect the other functions.
Set parameters after confirming the function of each terminal.
When the Pr. 267 setting was changed, check the voltage/current input switch setting. Different setting may cause a
fault, failure or malfunction. (Refer to page 183 for setting)
Make sure to perform calibration after changing the voltage/current input signal assigned to the terminal 4 with
Pr. 267 setting and the voltage/current input switchover.

PID automatic switchover control (Pr. 127)
The system can be started up without PID control only at a start.
When the frequency is set to Pr. 127 PID control automatic switchover frequency within the range 0 to 400Hz, the inverter
starts up without PID control from a start until output frequency is reached to the set frequency of Pr. 127, and then it shifts
to PID control. Once the system has entered PID control operation, it continues PID control even if the output frequency
falls to or below Pr. 127.

Selecting operation to be performed at the output of Upper limit signal, Lower limit signal, and PID
deviation limit signal (FUP signal, FDN signal, Y48 signal, Pr.554)
You can select the operation to be performed at the detection of upper, lower and deviation limit for the measured
value input. With Pr. 554 PID signal operation selection, signal output or signal output + alarm stop (E.PID) can be
selected for each of upper limit output signal (FUP signal), lower limit output signal (FDN signal), and PID
deviation limit signal (Y48 signal).

* When the settings for Pr. 131 PID upper limit, Pr. 132 PID lower limit, and Pr. 553 PID deviation limit, which corresponds with FUP, FDN, and Y48 signals,
are "9999" (no function), the signal is not output, or the alarm stop is not performed.
