6) Setting the time elapsed before PID control starts
You can specify a waiting time for PID control to prevent the inverter from starting PID control before the
control system becomes stable, for example, after start-up.
The inverter ignores feedback input signals, carries out operation at the frequency determined by the amount
of processing for the period of time specified with f359 and enters the PID control mode after a lapse of
the specified time.
7) PID control forward/reverse characteristic switch
PID input characteristics can be reversed.
Process quantity
Feedback amount
When characteristic is reversed according to parameters

When PID calculation reverse selection parameter f380 is 1: Set reverse characteristics.
 When characteristic is reversed using logic input terminal
Input terminal function 54/55: Assign to switch PID characteristics.
(Caution) If reverse characteristics is selected for parameter f380 and terminal input at the same time,
they become forward characteristic.
