Chapter 8 Applied Functions
The output frequency of the inverter goes through PID control in order to control the system process including the flow,
temperature and tension and so on.
APP-01 App Mode(application mode) : You can set the process PID functions by setting at No. 2 Proc PID(Process
PID).
APP-16 PID Output : Displays the present output value of the PID controller with the unit, gain and scale set in APP-42,
APP-43 and APP-44 reflected.
APP-17 PID Ref Value : Displays the currently set reference of the PID controller with the unit, gain and scale set in APP-
42, APP-43 and APP-44 reflected.
APP-18 PID Fdb Value : Displays the present feedback input of the PID controller with the unit, gain and scale set in
APP-42, APP-43 and APP-44 reflected.
APP-19 PID Ref Set : The reference value can be input if the reference type(APP-20) of PID control is set as
keypad(0:Keypad). If the reference type is set at values other than the keypad, the value set in APP-19 is ignored.
APP-20 PID Ref Source : Selects the reference input of PID control(the items marked in grey are supposed to be
provided soon in the future). If the V1 terminal is set as PID F/B Source, V1 cannot be set as the PID Ref Source. If F/B
Source is changed to another item, V1 can be set as Ref Source.

The set PID reference can be displayed in the monitor mode and APP-17 and monitored in the items set as No. 17 PID
Ref Value among CNF-06~08 of CNF.
APP-21 PID F/B Source : Selects the feedback input of PID control. This can be selected in the inputs other than the
keypad input(Keypad-1, Keypad-2) in the reference input type. The feedback cannot be set as the same input as selected
in the reference.
