  目前,常用的有两类:50Ω和75Ω的射频同轴电缆。特性阻抗75Ω射频同轴电缆常用于,故称为CATV电缆,传输带宽可达1GHz,目前常用CATV电缆的传输带宽为750MHz。(2)对称射频电缆对称射频电缆回路其电磁场是开放型的,由于在高频下有辐射电磁能,因而使衰减增大,并导致屏蔽性能差,再加上大气条件的影响,通常较少采用。

在连接时,将电缆的COM头插入计算机的COM接口,电缆另端圆形插头插入PLC的编程口内。如果计算机没有COM接口,可选用FX-USB-AW电缆将计算机与PLC连接起来。在连接时,将电缆的USB头插入计算机的USB接口,电缆另一端圆形插头插入PLC的编程口内。当将FX-USB-AW电缆插到计算机USB接口时,还需要在计算机中安装这条电缆配带的驱动程序。驱动程序安装完成后,在计算机桌面上右击“我的计算机”,在弹出的菜单中选择“设备管理器”,弹出设备管理器窗口,。

  采用对绞、对屏、总屏(或三线组合、组屏蔽、组屏总屏)等结构形式,具有介质损耗小、传输传号能力强、抗干扰性能好等特点,能可靠地传输微弱的模拟信号,可广泛地应用于发电、冶金、石油、化工、轻纺等部门的检测和控制用计算机系统或自动化装置,以及一般的工业计算机上。

分析起来,是因为启动时间太短,母线电容的电压瞬间被掏空了,而整流器瞬间有大的电流充进来,引起母线电压突然变高,这样母线的电压波动太厉害,瞬间可能会超过了700伏,加上了制动电阻,就可以及时消除这个波动的高压,让变频器工作在正常状态。还有一种特殊的情况,是矢量控制场合,电机的扭矩和速度方向相反,或者工作在零转速百分百扭矩输出的场合,比如吊机掉了重物停在半空中,收放卷场合需要力矩控制,都需要让电机工作在发电机状态,源源不断的电流会反充到母线电容中,通过制动电阻,就可以及时消耗掉这些能量,保持母线电压平衡稳定了。
