Some AC/BLDC/Linear motors are equipped with a Hall sensor type feedback device which provides information of motor's electrical commutation angle to the drive. This allows faster drive initialization after power-on as Phasing a.k.a. phase search can be skipped. Hall sensor is also necessary in the case where motor is not able to move freely in both directions when powered on (i.e. if axis rests at the end of mechanical travel or is vertical axis).

Many Hall sensors have differential outputs (non-inverted and inverted channels, just like differential encoder), however Argon has only single ended Hall sensor inputs which supports both output types (single ended and differential).

It is possible to connect a Hall sensor together with other feedback devices to the same feedback device port on Argon and IONI series drives.
