7) PID control forward/reverse characteristic switch
PID input characteristics can be reversed.
When characteristic is reversed according to parameters
Set
: PID forward/reverse characteristics selection=
1
(Reverse).
When characteristic is reversed using logic input terminal
Assign the terminal function number 54/55 (PID characteristics switching) to an input terminal.
(Caution) If reverse characteristics is selected for
and terminal input at the same time, they
become forward characteristic.
