Design of stepping motor control system based on special integrated circuits

In order to reduce the cost of developing products,alleviate the pressure of microcontroller and improve the stability and flexibility of the system,the design of stepping motor control system based on special integrated circuits is suggested in this paper.The microcontroller AT90CAN128,the stepping motor driver TMC262 and the stepping motor controller TMC429 are chosen in the motion control system.Once initialized,the system can control up to three 2-phase stepping motors simultaneously,and can perform all real time critical tasks autonomously.The test result indicates that the design of control system has the advantages of steady data transmission,high ratio of performance-to-price,and being convenient to be controlled etc,which achieves the expected effectiveness and requirement.
