A resolver is a type of absolute rotary encoder. It consists of an excitation coil in the rotor, and two pickup coils in the stator at a 90° angle.
One pickup coil has leads that are generally labeled S3 for positive and S1 for negative; and the other coil has S2 for positive and S4 for
negative. This section described how to connect and configure this board for use with a resolver.
A resolver also requires a reference input. Please see Section 6.2 on page 26 for information on connecting the reference.
