8.8 Sink logic/Source logic selection
With the basic function switch (SW1-No.3), the input circuit of the
driver can be switched between sink logic and source logic.
The output circuit of the driver can be switched between sink logic
and source logic by changing the wiring connection.
In the sink logic input circuit, a signal will be turned ON when the
current ows out of the input terminal.
In the source logic input circuit, a signal will be turned ON when the
current ows into the input terminal.
This switch is set to sink logic (OFF) at the time of shipment.
Set to sink logic or source logic based on the output circuit of the
external control device (programmable controller).
