Abstract

The invention discloses a stepping motor control system based on a programmable controller. The stepping motor control system comprises the programmable controller, a liquid crystal touch screen, a stepping motor driver, a stepping motor, a power conversion module and a current detection module. The programmable controller is respectively connected with the liquid crystal touch screen, the stepping motor driver, the power conversion module and the current detection module. The power conversion module is respectively connected with the stepping motor driver, the stepping motor and commercial power. The stepping motor is connected with the programmable controller through the current detection module. According to the system, control and monitoring of the stepping motor are realized by the touch screen and the programmable controller so that the development period is reduced, the operation reliability is enhanced and the system has the advantages of reliable performance, simple control and high control precision and has great popularization and demonstration value. Equipment transformation and upgrading are also facilitated by the flexibility of software.

Description

technical field [0001] The invention relates to the field of electromechanical equipment control, in particular to a stepping motor control system of a programmable controller. Background technique [0002] The stepper motor system is mainly composed of the drive control circuit and the motor, so that the stepper motor and the drive circuit device are effectively integrated into a complete system. [0003] A stepping motor is an electromagnetic device that transforms a pulse signal into a corresponding angular displacement (or linear displacement), and is a special motor. Generally, the motor rotates continuously, but the stepping motor has two basic states of positioning and running. When there is a pulse input, the stepping motor rotates step by step. Every time a pulse signal is given to it, it turns through a certain angle. . The angular displacement of the stepping motor is strictly proportional to the number of input pulses, and is synchronized with the input pulses ...
