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  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.

Characteristic selection (parameter or terminal input)
 When characteristic is reversed according to parameters
When PID calculation reverse selection parameter  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  and terminal input at the same time,
they become forward characteristic.
