SINAMICS G120变频器应用方案
在石化行业中,应用变频器对风机,泵类负载进行变频调速控制,不但可以延长风机,泵类负载的使用寿命,同时可以节约电能,提供系统的安全性和可靠性。以泵类负载为例,使用SINAMICS G120系列变频器90KW对泵类负载的驱动电机进行变频控制,同时结合西门子S7-300系列PLC完成整个控制系统的自动化控制。
西门子变频器SINAMICS G120系列在工业自动化控制领域应用广泛,为用户提供高精度的速度控制或转矩控制。它采用模块化设计,提供了高度的灵活性,便于用户使用,维护,并可以在带电的情况下更换模块。同时它还具有强大的通讯功能,能和多个设备之间进行通讯,使用户可以方便的变频器的运行状态并修改参数。西门子变频器SINAMICS G120系列的核心是控制单元,用户通过设定控制单元上的参数来实现变频器的正常运行。用户可以通过操作面板来设定变频器的参数,本文下面对西门子变频器SINAMICS G120系列的参数特点做一个简单介绍,供用户在配置时进行参考。
