版本：A/01安全注意事項
（1）主回路電源得電后即存在危險電壓。
（2）不允許將輸入端(1L1、3L2、5L3)接到輸出端(2T1、4T2、
6T3)或(B1、B2、B3)。
（3）不允許軟起動器輸出端(2T1、4T2、6T3)和(B1、B2、B3)
!
接補償電容或壓敏電阻。
（4）軟起動器與變頻器互為備用時，二者輸出端要彼此隔離。
（5）請勿嘗試修復損壞的元器件，請與供貨商聯(lián)系。
（6）散熱器的溫度可能較高，請勿觸摸。
（7）嚴禁在軟起動輸出端反送電。
（8）軟起動器在起動或停止狀態(tài)時，輸出側都存在高壓。目 錄

1CMC-LX系列軟起動器產(chǎn)品說明書
第一章 CMC-LX 軟起動器的作用及特點
1.1 作用
CMC-LX系列電機軟起動器是一種將電力電子技術，微處理器和
自動控制相結合的新型電機起動、保護裝置。它能無階躍地平穩(wěn)起動/
停止電機，避免因采用直接起動、星/三角起動、自耦降壓起動等傳統(tǒng)
起動方式起動電機而引起的機械與電氣沖擊等問題，并能有效地降低
起動電流及配電容量，避免增容投資。同時CMC-LX系列軟起動器內
部集成電流互感器，用戶無需外接。
1.2 特點
? 獨特的SCR觸發(fā)閉環(huán)控制算法
獨特的SCR閉環(huán)控制功能，專為標準負載和重型負載特殊設計。
用戶可根據(jù)負載情況選擇限流起動和電壓斜坡起動，實現(xiàn)絕對平滑的
無轉矩震蕩起動效果。
? 控制精度高實時高效
采用高性能的Cortex-M332位內核CPU執(zhí)行中心控制，速度快、
精度高、抗干擾能力強。
? 優(yōu)美的外觀
專利保護的主回路三進六出結構，內置電流互感器方案，接線方
便、可靠性高。
? 可配的標準Modbus-RTU協(xié)議
用戶在選型時可根據(jù)現(xiàn)場需要，選配帶標準Modbus-RTU通訊模
塊或不帶。
