6 Hall Sensor Signals Interface
6.1.1 Technical Data
6-2
6.1 Overview
Hall sensor signals provided by some sensor devices are used as easier recognition for motor pole position.
With hall sensor signals, the detecting function implemented on Sigma-5 is not required. Used sensor devices
must output each U/V/W hall sensor signals. The Interface block diagram is shown below.
