针对螺旋焊管生产机组在生产过程中出现的递送机上下辊不同步运行造成的顿板和烧穿问题，设计了一拖二控制系统。该系统以 Profibus DP 方式与 PLC 主站通讯，通过 Starter 软件对SINAMICS DCM 6RA80控制器进行参数设置和PLC程序运算处理，实现1台控制器对上下辊电机同步控制。上位机采用CP5711连接到PLC主站，对运行参数进行监控。实际运行表明，递送机速度误差为±0.02 m/min，满足生产工艺要求，系统运行同步、稳定。

Aim at the problems of pausing plate and burning through during SAWH pipe production course, which caused by the reason that the up and down rollers of delivery machine are not synchronous, a kind of one-to-two control system was designed. This system communicates with PLC master station in Profibus DP mode, through the parameter setting of Starter software on the SINAMICS DCM 6RA80 controller and the processing of PLC program operation, the goal that one controller synchronously controls two motors of up and down rollers comes ture. The upper computer was connected to PLC master station through CP5711, and monitors the running parameters. Actual operation shows that delivery machine speed error is ±0.02 m/min, meet the requirements of production process, and the operation is synchronous and stable.
