you can connect the axis 1 control connector to one drive using analog
outputs 1 and 3, and connect the axis 2 control connector to another drive
using analog outputs 2 and 4. You can connect Hall effect sensors that
are used for initializing the sinusoidal commutation to the Feedback
Connector. Refer to Figure 3-12 for a diagram that demonstrates this
configuration.

You must connect the digital I/O cable from your National Instruments
motion controller to the UMI-7774/7772 to promote connectivity with the
Hall effect sensors.
Note
The Hall effect sensor connections are shown on Pins 5, 6, and 7 in Table 3-5.
