多轴同步伺服运动系统在预精焊生产线上的应用

在螺旋焊管预精焊生产过程中精焊时，为了保证多组V形辊道能够正常同步运行，采用了多轴同步伺服运动系统，并对该系统进行了通讯配置、软件和硬件的编制调试。使用PROFINET和SERCOS总线实现了西门子PLC和倍福PC、倍福PC和力士乐伺服驱动器的连接，并通过报文信息包进行信号的传输；以倍福PC为主控制器进行虚拟主轴的编程，并通过虚拟主轴控制多个从轴来实现同步功能；通过对驱动器速度环和位置环的配置和调试，最终实现稳定的同步功能。实际使用结果表明，该多轴同步伺服运动系统的同步功能稳定，确保了精焊质量。

Application of Multi-axis Synchronous Servo Motor System in Pre-finishing Welding Production Line

In order to guarantee synchronous operation of SAWH pipe multiple sets of V-shaped roller in finish welding, the multi-axis synchronous servo motor system was adopted, and the communication configuration, software and hardware debugging were conducted for this system. Using PROFINET and SERCOS bus to realize the link of Siemens PLC (programmable logic controller) to Beckhoff PC (personal computer), and the link of Beckhoff PC to Rexroth servo drives;used message packets to transmit signal; the Beckhoff PC was used as master controller to conduct virtual axis programming, and through the virtual axis control multiple auxiliary axis to realize synchronization function; it finally realized the stable synchronization function through configuration and debugging of drive speed loop and position loop. The practical use results showed that the synchronization function of multi-axis synchronous servo motor system was stability, ensured the finish welding quality.
