Analog In¶

Analog sensors usually output a voltage or a resistance that can be interpreted by the firmware. When the output is a voltage, the signal can be directly read by the analog input, but if it’s a resistance (e.g. resistance temperature detectors), a voltage divider must be used to generate a voltage equivalent to the resistance.

Important

If your servo drive does not incorporate a voltage divider itself, you must attach one separately.

SOMANET servo drives come with a default configuration for the analog inputs that can be alternated on request.

For details please refer to SOMANET Node’s Analog In configuration or to SOMANET Circulo’s Analog In configuration .

Using single-ended sensors on differential inputs¶

A single-ended encoder can be attached to the differential ports, if the voltage range fits only to the differential inputs. The signal must be connected to the + pin of the Analog In and the Ground to the - pin.
