An electronic control module is provided. The electronic control module is operably connected to a power supply for providing power to a motor. The electronic control module includes an input device, a processor coupled to the input device, and first and second current supply lines. The processor is configured to generate a command signal in response to an input supplied by the input device and transmit the command signal to the motor. The command signal controls an operating point of the motor. The first and second current supply lines are operably connectable to the motor and the processor. At least one of the current supply lines, the input device and the processor are adapted to utilize the current supply lines both to transmit power to the motor and to transmit the command signal to the motor over the current supply lines.
