舒张届3199变频器接线图 - 变频器,双电源上的接线柱,R,S,T各表示什么?
符尝琳15261715829 ______ 在变频器的接线中,主线路有电源和负载的接线端子,其中R、S、T三接线柱分别接入电源的A、B、C相,有的变频器连线图上有“L1/R、L2/S、L3/T”标示. 这里的“R、S、T”即代表接入电源的相序. 附带说一下,变频器主线路输出接入负载的端子一般用字母U、V、W表示.也有例外的情况,接线时一定要看清连线图.
舒张届3199fshtu ht6000e变频器的说明书起动接线图 -
符尝琳15261715829 ______ 变频器的接线原理类似,例如下图:注:1.端子L1/2/3丹380V进线端,接箱内交流接触器,U/V/W丹出线端接电机;2.端子PE接地端必须接地;3.端子12与18丹进控启动/停止,(端子12与27必须启接,进控信号必须丹无源+接点);4.端子60(...
舒张届3199三菱变频器的L1/R、L2/S、L3/T的接线端子接什么地方? -
符尝琳15261715829 ______ l1/r的接线端子在变频器背面左下数第一个的位置接口,然后l2/s在他后面偏下的位置,并且有红色标志标明,最后l3/t则位于机器背后中央位置,很显眼.
舒张届3199如何接连接变频器与电机? -
符尝琳15261715829 ______ 如果只是简单的运用,只需要接主接线端子,一般的是R/S/T为进线,接电源,U/V/W为出线,接电机就可以了.如果需要,后面还有两个端子接刹车电阻 但如果需要使用外部端子控制变频器的运行,根据需要不同,控制方式也不同,同时参数还要做相应的修改才可以,如果要和上位机进行通讯,则涉及的内容更多,是很难用几名话说清楚的,而且每个品牌/或者同一个品牌不同系列的变频器也不一样,需要分别对待.还是要根据你的需求来定,你可以把要求说清楚点,看大家能不能帮上你
舒张届3199第一图接第二图的变频器,怎样接呢? -
符尝琳15261715829 ______ 第一图绿端子红线接第二图FWD,黑线接COM;第一图橙端子红线接第二图右侧的VCC,灰色线接AV1,黑色线接GND.接线就这样,关键是设置变频器,设置不对也不能正常工作.
舒张届3199变频器电机之间屏蔽线的接法 -
符尝琳15261715829 ______ 1.屏蔽线是单边接地的!你在变频器侧接了地那么现场电器设备就不用再接地,反之在现场接了地则在变频器侧不用再接地. 2.电机必须有接地线!可以单独再用一根线做地线用. 3.380V工业动力配电主线一般没必要用屏蔽线!变频器与电机之间直接用一根四芯线(红黄绿+蓝)就行.选好线径! 屏蔽线作用是防止干扰、防雷等,自控仪表的信号线一般必须用屏蔽线.

舒张届3199这是个宏升卓越变频施工升降机变频器的接线图,我想知道它是怎样接线的? -
符尝琳15261715829 ______ 你这个图是变频器的接线图,几乎所有的变频器都有这么一张图.如何看变频器的接线,你可以给它划分几部分:1、一次线路的输入输出2、二次线路的输入输出(数字量和模拟量) 比如R/S/T是你的输入一次线路,U/V/W是输出给电动机的.+10V,AL1/AL2/com是你的模拟量电压/电流输入,AO1是你的模拟量电压/电流输出(根据你内部设定里决定到底是电压,还是电流) 你的SW1就是的数字量控制输入信号.你的R1A/R1B/R1C是你的数字量控制输出信号.估计你要的接线图,包括现场按钮(上,下,到位)这样的信号,这个图纸是整个控制图.你要看你的电路图,跟变频器的图没太大关联.
