2.4.2. Hall-Effect Inputs
The Hall-effect switch inputs are recommended for AC brushless motor commutation but not absolutely
required. The Hall-effect inputs accept 5-24 VDC level signals. An invalid Hall state (0,0,0) or (1,1,1) will
generate a "Hall Fault" axis fault.
Refer to
for Hall-effect device phasing.
