又称为SoftStarter。它不仅实现在整个起动过程中无冲击而平滑的起动电机，而且可根据电动机负载的特性来调节起动过程中的参数，如限流值、起动时间等。此外，它还具有多种对电机保护功能，这就从根本上解决了传统的降压起动设备的诸多弊端。发展趋势编辑随着国产变频器产业的迅速发展，变频器的价格不再高高在上，它不仅解决了电机启动产生大冲击电流的问题，并且具有很好的节能效果，因此，曾经风光一时的软启动器似乎有些没落，声音越来越小。但是软启动器面临的替代压力确实越来越大，[1]这种情况在尤为明显。由于工业技术一直较为落后，在十多年前，的变频器产业刚刚起步，没有定价权，国内市场大部分为品牌占据，变频器的成本一直居高不下。

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。

给继电器输入一组电压，且在供电回路中串入电流表进行监测。慢慢调高电源电压，听到继电器吸合声时，记下该吸合电压和吸合电流。为求准确，可以试多几次而求平均值。释放电压电流也是像上述那样连接测试，当继电器发生吸合后，再逐渐降低供电电压，当听到继电器再次发生释放声音时，记下此时的电压和电流，亦可尝试多几次而取得平均的释放电压和释放电流。一般情况下，继电器的释放电压约在吸合电压的10～50%，如果释放电压太小（小于1/10的吸合电压），则不能正常使用了，这样会对电路的稳定性造成威胁，工作不可靠。电符号和触点编辑继电器线圈在电路中用一个长方框符号表示，如果继电器有两个线圈，就画两个并列的长方框。同时在长方框内或长方框旁标上继电器的文字符号“J”。

采用交—直—交工作方式，即是输入为交流电源，交流电压三相整流桥整流后变为直流电压，然后直流电压经三相桥式逆变电路变换为调压调频的三相交流电输出到负载。当变频器刚上电时，由于直流侧的平波电容容量非常大，充电电流很大，通常采用一个起动电阻来限制充电电流，常见的变频起动两种电路，如图1所示。充电完成后，控制电路通过继电器的触点或晶闸管将电阻短路，起动电路故障一般表现为起动电阻烧坏，变频器报警显示为直流母线电压故障，一般设计者在设计变频器的起动电路时，为了减少变频器的体积选择起动电阻，都选择小一些，电阻值在10～50Ω，功率为10～50W。当变频器的交流输入电源频繁通时，或者旁路接触器的触点接触不良时。

继电器的触点有两种表示方法：一种是把它们直接画在长方框一侧，这种表示法较为直观。另一种是按照电路连接的需要，把各个触点分别画到各自的控制电路中，通常在同一继电器的触点与线圈旁分别标注上相同的文字符号，并将触点组编上号码，以示区别。继电器的触点有三种基本形式：1.动合型（H型）线圈不通电时两触点是断开的，通电后，两个触点就闭合。以合字的拼音字头“H”表示。2.动断型（D型）线圈不通电时两触点是闭合的，通电后两个触点就断开。用断字的拼音字头“D”表示。3.转换型（Z型）这是触点组型。这种触点组共有三个触点，即中间是动触点，上下各一个静触点。线圈不通电时，动触点和其中一个静触点断开和另一个闭合，线圈通电后。
