Step 5 PNP/NPN Mode Selection
The S100 inverter supports both PNP (Source) and NPN (Sink) modes for sequence inputs
at the terminal. Select an appropriate mode to suit requirements using the PNP/NPN
selection switch (SW1) on the control board. Refer to the following information for detailed
applications.
PNP Mode (Source)
Select PNP using the PNP/NPN selection switch (SW1). Note that the factory default
setting is NPN mode. CM is is the common ground terminal for all analog inputs at the
terminal, and P24 is 24V internal source. If you are using an external 24V source, build a
circuit that connects the external source (-) and the CM terminal.
