This article states how to use PLC, stepping motor and torque sensor to complete the automatic testing system. Then we can effectively solve the waste and inefficiency problems caused by traditional manual detection. At the same time we main analysis how to use Omron PLC to control the three stepping motors.The essence of this article is to automate the torque testing equipment, and analysis how to achieve this target. Besides, introduce the performance parameter of PLC and torque sensor, stepping motor. Then we can make a better torque testing system to meet customer requirements. Of course there is still some room for improvement.Then introduce the whole process of this design, from the program of system control to the circuit wiring diagram and PLC programming. At las...
