触摸屏画面由ProTool等软件进行设计,然后先通过编程电脑调试,合格后再到触摸屏。触摸屏画面总数应在其存储空间允许的范围内,各画面之间尽量做到可相互及强制切换。 (1)主画面的设计 一般的,可用欢迎画面或被控系统的主系统画面作为主画面,该画面可进入到各分画面。各分画面均能一步返回主画面。若是将被控主系统画面作为主画面,则应在画面中显示被控系统的一些住要参数,以便在此画面上对整个被控系统有大致的了结。
西门子电机软启动器的常见故障
1、电动机起不来
电动机起不来的原因大致分两种情况:一是六只可控硅的其中一只触发不可靠或是不导通,此时一相电路通过的是半波直流,电动机的两相绕组通过的直流对电动机起到了制动作用,不仅电机起不来,严重的还会烧毁电机和可控硅。二是启动参数或启动曲线不合适造成电机起不来,这是常见故障。前者在使用过程当中会发生,但几率低于接触器的故障率。后者多发生在次投运调试,调试好以后就不会出现。多数的厂家不会出现此现象,启动程序性能好,出厂值设定的适用性强。只有很少厂家的产品需要厂家自己去调试。
