根据计算结果，有序地向逆变桥中各逆变器件发出“通”和“断”的动作指令。(2)调节频率时，一方面，调制波与载波的周期要同时改变(改变的规律本文不作介绍)；另一方面，调制波的振幅要随频率而变，而载波的振幅则不变，所以，每次调节后，所胶点的时间坐标都必须重新计算。要满足上述要求，只有在计算机技术取得长足进步的20世纪80年代才有可能，同时，又由于大规模集成电路的飞速发展，迄今，已经有能够产生满足要求的SPWM波形的集成电路了。西门子420变频器PID调试：总结在变频器page5-13.14详细讲解在说明书page10-84.85..86.87.88.89.90.91.92.93.94重要几个参数为1.P0004改为22.page10-62.P2200改为1允许PID控制器投入3.P2257PID设定值的斜坡上升时间p2258PID设定值的斜坡下降时间P2261PID设定值的滤波时间常数P2264PID反馈信号P2265PID反馈滤波时间常数P2267PID反馈信号的上限值P2268PID反馈信号的下限值P2269PID反馈信号的增益P2270PID传感器的反馈型式P2280PID比例增益系数P2285PID积分时间P2291PID输出上限P2292PID输出下限P2293PID限幅值的斜坡上升/下降时间噪声与振动及其对策采用变频器调速。

检查变频器内A10主板、A22电源板上的LED指示灯均正常，用试电笔测变频器的进线电源，发现有一相显示不正常，用万用表测量三相结果为:Vab=390V，Vac=190V，Vbc=190V。经检查系进线端子排处接触不良。ready指示灯是变频器内各种状态信息的综合反映，当它不亮时可提示维护人员注意变频器尚未就绪。此时在进线电源不正常时变频器的故障记录中未能反映未就绪的原因，可能与电路的设计有关。(4)调试过程中变频器启动后即过流跳闸变频器供货方与被控设备的供货方因沟通上的原因，在容量上不匹配(电机功率为30kW)。将变频器的控制模式选为矢量控制，在输入电机参数时，变频器自动将电机的额定电流60A限定在45A。

通过改变控制角α或导通角θ，改变负载上脉冲直流电压的平均值UL，实现了可控整流。小功率塑封双向可控硅通常用作声光控灯光系统。额定电流：IA小于2A。大；中功率塑封和铁封可控硅通常用作功率型可控调压电路。像可调压输出直流电源等等。大功率高频可控硅通常用作工业中；高频熔炼炉等。鉴别编辑可控硅从外形上分主要有螺旋式、平板式和平底式三种，螺旋式的应用较多。可控硅有三个电极---阳极（A）阴极（C）和控制极（G）。它有管芯是P型导体和N型导体交迭组成的四层结构，共有三个PN结。可控硅和只有一个PN结的硅整流二极度管在结构上迥然不同。可控硅的四层结构和控制极的引用，为其发挥“以小控大”的优异控制特性奠定了基础。

故在电路中起着自动调节、保护、转换电路等作用。主要用于发电机、变压器和输电线的继电保护装置中，作为过电压保护或低电压闭锁的启动原件。[1]中文名电压继电器外文名Voltagerelay类别电气设备学科电工学作用自动调节、保护、转换电路分类过电压继电器、欠电压继电器目录1介绍2分类3电磁式电压继电器4静态电压继电器介绍编辑电压继电器是输入量、特性量为电压的量度继电器，分为过电压继电器和欠电压继电器。前者由于电压值增加达到整定值而动作，然后处于动后状态；后者由于电压值减少达到整定值而动作，然后处于释放状态。电压继电器有电磁型、晶体管型。电磁型电压继电器原理及结构如图1所示，当电压达到整定值时，铁芯将舌片吸合。
