Driving controls and diagnostic methods for communicating motors
In exemplary embodiments, methods for operating driving controls for communicating motors are disclosed. In an exemplary embodiment, a method generally includes controlling a transmit circuit of the driving control to generate an expected transmit signal for sending to the communicating motor, and detecting, using a transmit sense circuit in the driving control, the actual resulting signal generated by the transmit circuit signal before the actual resulting signal leaves the driving control and is transmitted to the communicating motor. The method also includes analyzing the detected signal to verify whether the transmit circuit in the driving control is working properly, by comparing the expected transmit signal to the detected actual resulting signal. Exemplary methods are also disclosed of analyzing receive circuits of driving controls to verify whether the receive circuits are working properly.
