ExtPID output can be used for drive 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 connect wiring for analog input. Set DRV-04
[Freq Mode] to “Ext. PID”, then ExtPID output functions as Drive 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 drive performs Accel/Decel
with output frequency. Another system can be connected via S0/S1 terminal.
