The Research Of PCI Interface Motion Control Board Based On FPGA

Motion-Control technology is the hard core of electromechanical integration technology. It is of great significance for enhancing our electromechanical integration technology to develop motion-control technology. MC is very important in the ONCS, because it is the most important to control the movement of the motor of each axis in the NC system and the precision of position control and performance of velocity adjusting are directly related to MC. In the present, all of the researches of ONCS focus on that of the PC-based NC control device, whose key is the research of Motion Control Board (MCB) which is used to control stepping or servo motor. To PC-NC, in some degree, the performance of MCB decides that of the whole NC system, further more, the development and application of technology of macroelectronics and Digital Signal Processing continuously improve the performance of MCB and greatly increase the level of integration and dependability.During the research, through the overall survey of ONCS and deep study of Motion Control Technology (MCT), facing the behindhand actuality of research of domestic MCT, to meet the practical requirements of the laser carving field, following the developing trend of the present MCT, drawing on the new production of the present ONCS and relating MCT, bringing forward the solution based on FPGA, we have developed a four-axis multifunctional MCB which is very original, powerful and flexible.In the paper, there are the following major contents:...
