　　RS485通信电缆特点：RS-485通讯电缆特性阻抗为120欧姆，导体为2*24AWG多股绞合镀锡铜丝，PE绝缘介质，由铝箔/聚酯复合带覆盖+镀锡铜丝90%覆盖共2层屏蔽，附有独立接地导线，工业灰色PVC外护套。

变频器接线要求1)变频器和电机的距离应该尽量的短。这样减小了电缆的对地电容，减少干扰的发射源。2)电机电缆应独立于其它电缆走线，其小距离为500mm。同时应避免电机电缆与其它电缆长距离平行走线，这样才能减少变频器输出电压快速变化而产生的电磁干扰。如果控制电缆和电源电缆交叉，应尽可能使它们按90度角交叉。与变频器有关的模拟量信号线与主回路线分开走线，即使在控制柜中也要如此。3)模拟量控制线选用屏蔽线，屏蔽一端接变频器控制电路的公共端(COM)，不要接变频器地端或大地，另一端悬空;动力电缆选用屏蔽或者从变频器到电机全部用穿线管屏蔽，或遵从变频器的用户手册。

The outer conductor knitting is usually 60%-80% suitable. The mould design and processing for insulation production are also key. It should ensure that the product reaches the ideal uniform structure and the e interface constant meets the design re



Oil-filled cable model HYAT armouring oil-filled cable HYAT22 HYYT23 HYAT23 HYAT53 oil-filled cable standard: YD/ t322-2013

The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 square, tell from some cable, power cable according to the demand of power grid more generally for 5 core, and control cable transmission control, some more, according to the terms of more than 61 core, but also can produce according to user re

使用程序状态功能监视数据块点击数据块工具栏上的监视按钮，自动切换到“数据视图”显示方式，数据块内的存储单元在线的数值在实际值列中显示，程序状态被激活后，不能切换“声明视图”方式。结构的生成和使用结构的生成可以在数据块中或逻辑块的声明表中定义结构，下面介绍在数据块中定义的方法，在上面DB3数据块中，再定义一个结构，名为stack的结构由3个不同数据类型的变量组成。如下图所示：在“ARRAY”下面的INT，按回车键，在该单元下面生成一个空白行，在名称输入stack，在类型列单元点右键选择复杂数据类型，选择STRUCT，（也可以直接输入STRUCT），按回车后再改行下面出现新的行，按如图输入。
