4.6 J4 – Hall Sensor Input
Pin # Description
1 ISO +5 (20mA Maximum)
2 ISO Gnd)
3 Hall A
4 Hall B
5 Hall C
Table 10 – Hall Sensor Input Connector
Note: If the motor has differential Hall outputs, only connect the “+” Hall outputs to J4 and leave the “–”
Hall signals unconnected. (Do not tie to ground, the motor will be damaged.)
Note: If the Hall sensors require more than 20mA, an external +5V must be supplied.
(See application example 5.3)
