IOT Based Expandable Multi Stepper Motor Control System On CAN Bus

Abstract: The modern control applications require the simultaneous or individual controlling of multiple stepper motors which can be achieved by using the CAN bus. A CAN bus communication established using ESP-32’s Controller Area Network (CAN) controller and TJA1050 CAN transceiver. The entire system suggested here can be expanded by connecting an individual stepper motor controller to an existing system as needed or for future development via a CAN bus link. Using ESP32 IOT capabilities, developed industrial remote monitoring and control system sets motion control parameters of each stepper motor and controls each stepper motor’s position. The proposed system is compatible and capable of controlling any actuator. The whole arrangement is presented with the help of software and hardware design. The proposed approaches appear to be promising based on the experimental results.
