Resolver Actuator

The resolver actuator is configured by a constant-current excitation circuit. Figure 2.4 shows an actuator and its external
circuit. The current that drives the resolver can be controlled by the amplitude of the excitation clock signal applied on the
CARRIER pin and a current limiting resistor R connected between EXCOUT1 and EXCFBP.
