Analog Input (V1, I, or Pulse) and perform terminal 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 perform terminal 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 other system.

ExtPID output can be used for inverter target frequency. To activate this function, set analog input (V1, I, Pulse)
as a reference value to other system or set APP-81 [Ext. Ref Sel] to “Keypad” and set proper value in APP-82
[Ext. Ref Perc]. Set APP-83 [Ext. Fbk Sel] to Analog input (I, V1, Pulse) and conduct wiring. And set DRV-04
[Freq Mode] to “Ext. PID”, then ExtPID output functions as Inverter main speed reference (target frequency).
When Ext.PID Run signal is ON in the defined terminal in I/O-20~27, it starts its output and inverter performs
Accel/Decel with output frequency. Other system can be connected via S0/S1 terminal.
