8 Hall Sensor Signals Interface
This chapter describes the hall sensor signals interface of the Feedback Option Module.
8.1 Overview
Hall sensor signals provided by some sensor devices are used for easier detection of
motor pole position. Hall sensor signals do not require the detection function implemented
on the SERVOPACK. The sensor devices used must each output U/V/W Hall sensor sig-
nals. The block diagram of the interface is shown below.
