　1、電源電壓不足：變頻器的工作電壓達(dá)到規(guī)定的要求，如果電壓不足，變頻器就無法正常工作，從而導(dǎo)致無法啟動。

　　2、變頻器內(nèi)部組件損壞：變頻器內(nèi)部的電路組件如果損壞，變頻器就無法正常工作，從而導(dǎo)致無法啟動。

　　3、變頻器設(shè)置參數(shù)不正確：變頻器的參數(shù)設(shè)置不正確，可能會導(dǎo)致變頻器無法正常工作，從而導(dǎo)致無法啟動。

　　4、變頻器連接線路接觸不良：變頻器的連接線路如果接觸不良，可能會導(dǎo)致變頻器無法正常工作，從而導(dǎo)致無法啟動。

　　5、變頻器控制系統(tǒng)故障：變頻器的控制系統(tǒng)如果出現(xiàn)故障，可能會導(dǎo)致變頻器無法正常工作，從而導(dǎo)致無法啟動。

　　6、變頻器外部環(huán)境溫度過高：變頻器的外部環(huán)境溫度如果過高，可能會導(dǎo)致變頻器無法正常工作，從而導(dǎo)致無法啟動。

　　變頻器的6種調(diào)速方法

　　變頻器調(diào)速度快慢可以通過調(diào)節(jié)輸入電壓或頻率來實現(xiàn)，也可以通過調(diào)節(jié)輸出電壓或頻率來實現(xiàn)。

　　1.使用變頻器鍵盤上下鍵調(diào)整變頻器速度（上鍵加速，下鍵減速）

　　2.使用面板電位器調(diào)整速度

　　3.0-10V模擬量調(diào)整速度

　　4.0.20ma或者4-20ma調(diào)整速度

　　5.通過多段速指令調(diào)整速度

　　6.通過簡易PLC調(diào)整運行及速度
