摘　　要：针对控制系统中电机部分功能冗余及工业自动化流水线柔性化生产等问题,对工业机械手、包装机、浇注机等多电机协作的控制系统进行了研究,提出了一种基于DeviceNet现场总线的主从站式多轴电机控制系统。在控制系统中,采用CJ系列模块式可编程逻辑控制器(PLC),提高了系统的相对独立性、互换性和通用性,同时通过主站链接控制方式优化了系统控制,简化了主站设计、增加了系统可靠性。利用多轴电机控制系统平台以及NB-Designer软件仿真调试,对电机高低搭配运行的误差精度进行了重复测试。研究结果表明,在满足运行特性和精度要求的情况下,步进电机可替代伺服电机,完成不同的控制需要,这种不同电机高低搭配的系统经济性更好,在工业自动化生产中具有实际应用价值。Aiming at the problems of some functional redundancy of motor in control system and flexible production in industrial automation lines,and studying on the control system of multi motor coordination such as industrial manipulator,packing machine,casting machine,a control system for master-slave multi-axis motor based on DeviceNet field bus technology was put forward. Modular programmable logic controller（ PLC） was used in control system to improve the relative independence,interchangeability and versatility of system. At the same time the system was controlled by master connection mode to optimize the system control,simplify the master design and increase system reliability. The multi-axis motor control system platform and NB-Designer were used to test precision errors repetitively for different motor running.The running results indicate that stepper motor can replace the servo motor to complete different control needs when it meet the operating characteristics and precision requirements. This system with different motors has better economic benefits,and it has practical application value in the production of industrial automation.
