brief Introduction of the content
Based on the requirements of professional post ability, this book systematically introduces the electrical control principle of factory electrical control equipment, the analysis and troubleshooting of typical machine tool control circuits from the practical application of engineering. At the same time, taking the widely used Mitsubishi FX series PLC as an example, the structure, working principle, instruction system, program design and application of PLC are introduced. The contents of this book include: common low-voltage appliances, relays? The basic link of contactor control circuit, typical machine tool electrical control, Mitsubishi FX series PLC and instruction system, PLC program design and PLC control system design are six modules. In terms of content arrangement, this book not only pays attention to introducing the latest technology in the field of electrical control, but also pays attention to the cultivation of students' knowledge and ability in higher vocational education, emphasizing the integration of theory with practice and cultivating students' practical ability, ability to analyze and solve practical problems, engineering design ability and innovative consciousness. This book is compiled by the editor on the basis of years of teaching, teaching reform and scientific research in electrical control and PLC and related fields. The content structure is novel, and the "modular" theory and practice integrated structure system is adopted to arrange the content. Each module includes knowledge goal, ability goal, theoretical knowledge, basic skills training and comprehensive project training, and is equipped with appropriate thinking and exercises to facilitate the learning of knowledge and skills. This book can be used as a teaching material for electromechanical, automation and electronic information majors in higher vocational colleges, as well as for related majors in applied undergraduate colleges, adult education, technician colleges, correspondence colleges, secondary vocational schools and other colleges, and can also be used as a reference book for electrical technicians and a teaching material for electrical industry training. In order to facilitate teaching, this book is equipped with electronic courseware, simulated test papers and problem solving. All schools that choose this book as a teaching material can get it for free.
