Step Motor Control Based on PLC

Abstract

Stepping motor has the advantages of simple control, accurate positioning, no accumulated error and low rotor inertia. Stepping motor has a very bright performance in the field of automation, which has obvious propulsion effect on the formation of mechatronics system. After using the stepping motor, the error of the motor is reduced, and the positioning of the motor is more accurate. At the same time, combining the stepping motor with PLC can significantly enhance the advantages of the stepping motor. In this paper, the stepping motor based on PLC control is the main research topic. On the hardware design of the system, the design is made from the following aspects: the selection of PLC model, I/O points of input and output, the principle of automatic control and control circuit. In the software design of the system, the control program of the system is analyzed to ensure that the design requirements are met, and it has certain practical application value.
