视频信号传输线有同轴电缆(不平衡电缆)、平衡对称电缆(电话电缆)、光缆。平衡对称电缆和光缆一般用于长距离传输,对于宾馆酒店等建筑一般采用同轴电缆传输视频基带信号的传输方式。当采用75-5同轴电缆时,一般传输距离在300m时,应考虑使用电缆补偿器。
变频器的保护功能动作时,继电器的常闭触点控制接触器电路,会使接触器断开,从而切断变频器的主电路电源。不应以主电路的通断来进行变频器的运行、停止操作。需用控制面板上的运行键(RUN)和停止键(STOP)或用控制电路端子FWD(REV)来操作。变频器输出端子(U、V、W)经热继电器再接至三相电动机上,当旋转方向与设定方向不一致时,要调换U、V、W三相中的任意两相。变频器的输出端子不要连接到电力电容器或浪涌吸收器上。

在需要低成本实现位置、角度等控制目标的应用场景。步进电机是常见的应用器件。在使用步进电机的过程中,有哪些需要注意的问题点?无接线图情况下如何连接驱动器与步进电机?——可以使用万用表的通断档,测量电机任意两线间的通断。若测得两线导通,则说明此为电机的一个绕组,应接入驱动器对应的同一输出,如A+,A-两个位置。电机运行方向反向?——将电机的任意一个绕组的线调换位置,如原本A+接红色电缆,A-接黄色电缆,更改为A+接黄色电缆,A-接红色电缆。
这种区别是由历史原因造成的,而不是由于技术原因或生产厂家。同轴电缆的这种结构,使它具有高带宽和极好的噪声抑制特性。同轴电缆的带宽取决于电缆长度。1km的电缆可以达到1Gb/s~2Gb/s的数据传输速率。
