This illustrates dual use of PID controller (APP-02) and External PID controller. Set APP-81 [Ext. Ref Sel] to
Analog Input (V1, I, or Pulse) and connect wiring for analog input. To give the digital reference, set APP-81 [Ext.
Ref Sel] to “Keypad” and set proper value in APP-82 [Ext. Ref Perc]. Set the Ext. PID Feedback among V1, I,
Pulse in APP-83 and connect wiring for analog input. External PID Ref. and feedback are connected to PID
controller. When Ext.PID Run signal is ON to the defined terminal in I/O-20~27, it starts its output. S0/S1 terminal
can be used to connect to another system.
