摘要
讨论了利用SIEMENS6RA70系列直流传动控制器的主从控制模式解决中板生产线上双边剪夹送辊传动系统的速度同步和负荷均衡问题的方法。采用该方法,可以有效地防止剪切过程中出现钢板跑偏及负荷不平衡等现象,从而大大降低故障时间,提高生产率。
An approach to speed synchronization and load distribution of the pinch roll system of double side shear in medium plate plant is discussed in this paper,which uses the master/slave control mode of SIEMENS 6RA70 series digital DC converter. The approach can prevent the off-tracking of the would-be-cut plate and keep the load of motors balanced,thus decreasing the failure time and improving productivity.
