摘　　要：介绍了无缝钢管生产线上步进式冷床的电气传动和控制系统。通过使用SINAMICS系列变频器实现了步进式冷床升降装置的主从运动控制,包括快速制动及速度切换时的快速能量回馈;以S7-300系列的315-2DPCPU作为自动化系统的控制核心;使用S7-GRAPH语言编写关键程序;HMI人机界面实现对设备和钢管实时监控与跟踪。步进式冷床控制系统采用上述设计选择,可有效提高设备运行的稳定性,保证产品的高品质。Elaborated in the essay are the electric drive and control system of the seamless steel tube walking- beam cooling bed. The controls of the master-slave movement of the said cooling bed＇ s lifting device are realized via the SINAMICS frequency converter, including quick energy feed back for quick braking and speed switching. The 315-2DP CPU of S7-300 Series are used as the control core of the automation system, and the S7-GRAPH lan- guage is used for critical programming; HMI realizes real-time monitoring and tracking of the equipment and the material as well. As a result, operation stability of the equipment is improved, and the excellent product quality ensured.
