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.
Claims19
A dynamoelectric machine assembly for connection to a system controller, the assembly comprising:
- a multi-contact connector for coupling the assembly to the system controller, the multi-contact connector including an input contact for receiving a control signal from the system controller and an output contact for sending a data output signal from the assembly to the system controller;
- and
- a processor coupled to the input contact, the processor 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.
A dynamoelectric machine assembly for connection to a system controller, the assembly comprising:
- a multi-contact connector including at least one input for receiving a control signal from the system controller;
- and
- a processor coupled to the input to receive the control signal, the processor configured to determine if the control signal is a PWM signal or a serial communication signal, and to operate the assembly in a PWM mode when the control signal is a PWM signal and to operate the assembly in a serial mode when the control signal is a serial communication signal.
A dynamoelectric machine assembly for connection to a system controller, the assembly comprising:
- a plurality of operating parameters stored in a memory device;
- at least one input for receiving a PWM control signal from the system controller and a serial communication signal from the system controller;
- and
- a processor coupled to the input to receive the serial communication signal and the PWM control signal, the processor configured to change the plurality of operating parameters stored in the memory device in response to the serial communication signal, and to operate the assembly in accordance with the PWM control signal and the plurality of operating parameters stored in the memory device.
