ABSTRACT:
A dynamoelectric machine assembly for connection to a system controller. The assembly includes at least one input contact for receiving a control signal from the system controller and a processor coupled to the input contact. The processor is configured to operate the assembly in a pulse width modulation (PWM) mode when the control signal is a PWM control signal and to operate the assembly in a serial mode when the control signal is a serial communication signal.
