AI Technical Summary
In existing motor controllers, there is a lack of real-time detection of the status of the docking plug-in, which makes it difficult to determine whether it is a fault caused by the connector connection problem when the contact impedance changes instantaneously.
A detection circuit is designed, including a current sensing circuit, a comparison circuit and a latch circuit, which monitors the current information of the connector in real time, and compares it with a preset threshold through the comparison circuit. When the current value is less than the threshold, the latch circuit latches the abnormal information, and the controller performs abnormal processing after receiving it.
Real-time monitoring of impedance between docking plug-ins and fault latching, can detect instantaneous faults in the motor controller, troubleshoot occasional faults caused by the connector, and improve the reliability of the motor controller.
