杜禄熊889变频器一般怎么接线? -
路琬适19784805837 ______ 变频器380V的主要接线端子为输入:R;S;T;输出:U;V;W;还有制动单元的 端子:P+;P;R;R';,普通常用接法就是把输入和 输出接上用键盘就 可以 调速,如果需要外部控制可 在控制板端子上找相应功能即可,参见产品说明; 端子功能分为:方向控制,多段速控制,故障复位,程序控制辅助继电器输出等等功能,每个厂家的变频器端子功能都有定义,可参见产品说明书!

杜禄熊889220v1.5kw变频器正反转接线路 -
路琬适19784805837 ______ 在变频器二次端子上找到com(公共线)fwd(正转)rew(反转)三个接线点,外引接上三位置旋钮就行了.注意:要在参数里改设置为外控.

杜禄熊889变频器怎样用行程开关控制正反转接线图 -
路琬适19784805837 ______ 变频器上有正反转控制端子,查下变频器说明书就知道啦,关于控制方面就是普通的接触器正反转控制,用两个行程开关控制到位停止或者反转就行了. 变频器(Variable-frequency Drive,VFD)是应用变频技术与微电子技术,通过改变电机工...

杜禄熊889变频器正反转如何控制的 -
路琬适19784805837 ______ 1、正转控制 按下按钮SB4继电器KA1线圈得电,KA1的1个常闭触点断开,3个常开触点闭合KA1的常闭触点断开使KA2线圈无法得电. KA1的3个常开触点闭合分别锁定KA1线圈得电、短接按钮SB1和接通STF、SD端子STF、SD端子接通,相...

杜禄熊889变频器正反点动怎么接线
路琬适19784805837 ______ 正转信号+点动信号或者反转信号+点动信号 接线按照说明书对应端子连接就行

杜禄熊889德力西cdl - e系列变频器,外部端子怎么接正反转 -
路琬适19784805837 ______ di1+com,是正转;di2+com是反转,di1~di6为多功能端子,可以在变频器的参数中进行定义.

杜禄熊889变频器如何接线.能不能只用开关来连接变频器 -
路琬适19784805837 ______ 一般变频器上有5-6个数字输入端子,它的功能可以通过参数设置,比如正传、反转、频率加减、故障复位、PID暂停等功能,设定所需的功能,将对应的端子和公共端(一般是COM或GND,不同变频器稍有区别)通过开关或自锁型的按钮连起来就可以了. 另外就是,变频器默认的是键盘启停,在变频器的面板上,,绿色的按键,FWD正传,REV反转,或者是RUN运行,另一个绿色的就是切换方向,,,,,红色的STOP停止

杜禄熊889我想用变频器控制电机正反转,一去一回就自己停,怎么接线,最好是发接线图,谢谢, -
路琬适19784805837 ______ 在变频器设置,

杜禄熊889现在我想给变频接个开关控制反转(离变频很远)怎么接线? -
路琬适19784805837 ______ 变频器DI端子可以设定不同的功能,你可以接一个转换开关到DI端子上,或者用两个中间继电器,DI端子的接线具体还要看变频器说明书~
