Multiphase Motor Commutation (COMM)
The COMM function generates phase commutation signals for a variety of brushless motors, including
three-phase brushless direct current motors. It derives the commutation state directly from the position
decoded in FQD, eliminating the need for hall effect sensors.
The state sequence is implemented as a user-configurable state machine, providing a flexible approach
with other general applications. A RCPU offset parameter is provided to allow the RCPU to advance or
retard all swtiching angles on the fly. This feature is useful for torque maintenance at high speeds. See
