Design of Multi-axis Motion Control System for Stepping Motor

In order to improve the load characteristics of stepper motor, give full play to the potential performance of a stepper motor, achieve higher performance, a stepper controlling system has been developed. High-speed microcontroller-based controller, enhanced parallel port (EPP) as a communication interface, Field Programmable Gates Array (FPGA) to achieve pulse signal generator, use of PC rich resources, message-driven Windows systems thinking applied to microcontroller program development, to achieve a step pulse signal a continuous, stable and adjustable linkage interpolation and modular system software. Experiments show that the control system for seam tracking control of scanning, the movement speed of up to 0.5 m/s, velocity error is less than 5% and weld Inspection deviation of less than 1mm. it not only has accurate positioning and reliable real-time, control, flexibility, speed to run wide, and strong anti-interference performance, man-machine interface, convenient, but is it good adaptability and self-protection capabilities, improved the stability and reliability of driver.
