Hall Sensors Circuitry
Motor Hall sensors should be connected to opto-isolated digital inputs on connector A2/B2/B3
(Halls). The Hall sensors must be connected to three consecutive inputs Hall_A,Hall_B, Hall_C. The
first input mode must be configured to mode 23-Hall A.
Figure 17. Motor Hall sensors
It is recommended that Hall sensors be used with incremental encoders. Typically, Hall sensors
are called Ha-Hb-Hc, or Hu-Hv-Hw, or H1-H2-H3, which correspond to the motor phases. A typical
Hall sensor is an open collector (NPN) type and requires a 5 VDC power supply.
Any three consecutive digital inputs can be used as Hall sensor inputs.
Motor Hall sensors are wired as standard digital inputs.
