When this signal is assigned to the input terminal, PID control is enabled
when this signal is ON.

The set point set in Pr.1460 to Pr.1466 can be selected by combining the
ON/OFF status of the signals.

PID control is switched between forward and reverse action without
changing parameters by turning ON this signal.

When the PID calculation result is not reflected to the output frequency
(Pr.128< "2000"), the PID signal turns OFF at turn OFF of the start signal.
When the PID calculation result is reflected to the output frequency (Pr.128 ≥
