The connector is configured in such a way so that all eight motor wires can be
connected in all possible configurations. Considering an eight-wire motor in a bipolar
configuration (series- or half-winding), two wires will be left floating. The NC pins are
available to accommodate the two floating wires.
The DC bus connection is placed between wires of two different phases to
accommodate the center tap of a winding in unipolar configurations. Refer to Table 3
for details on how to connect the motor wires to J8 for all possible configurations.
