摘　　要：针对全电动注塑机控制系统的抗干扰能力及控制精度较差的特点,分析了注塑机高速、高精度性能对运动控制系统性能的要求,提出了一种根据各个层的分工独立设计软件的功能模块的方法,并选择西门子S7-300PLC作为控制中枢,实现了一种全电动注塑机的伺服运动控制系统。实际运行结果表明,该系统的抗干扰能力及控制精度得到了进一步的提高,能够较好地满足了全电动注塑机控制的速度、精度和稳定性要求。Aimed at the shortcomings of the anti--interference ability and control precision of fully-electric injection molding machine control system can not meet the requirements,analyzes its control requirements for motion control system, proposes a method accord- ing to the division of labor and independent design of each layer of software＇s functionality modules and designs an servo motion control system based on the Siemens S7-300 PLC. The practical results show that the anti--interference ability and control precision of the system are improved greatly, and it meets the requirements of the control precision, control speed and stability greatly.
