I/O Signal Specifications

Position feedback input: sin/cos sensor

Two control lines are internally configured to read a sin/cos sensor. Position
Feedback A (pin 31) provides the sine signal, and Feedback Position B (pin 32)
provides the cosine signal. The device must be set up with one sensor revolution
per mechanical revolution.

These signal tolerances must be maintained over the controller's voltage and
temperature ranges and the vehicle's speed range. The sin/cos waveform peaks
must be away from V
