我用三凌二NPLC與2AD和變頻器連接，用觸模屏操作各功能，運行時(shí)屏上設定30H，變頻器也顯示30HZ，運行正常，可運行一段時(shí)間電機轉速下降，變頻器顯示10HZ左右而屏上還是顯示30HZ，電機發(fā)熱歷害，請問(wèn)各高手是怎么會(huì )事。

樓主查一下在運行過(guò)程中負載是否發(fā)生突變，變頻器容量和電機功率是否匹配？選用的是普通電機還是帶有強拍風(fēng)的變頻電機，要是冷卻風(fēng)扇裝在電機軸上進(jìn)行冷卻的話(huà)10Hz頻率運行時(shí)間長(cháng)電機發(fā)熱是正�，F象，只要保持在70度以?xún)仁菦](méi)有任何問(wèn)題的，看一下故障時(shí)變頻器面板上的輸出電流是否超出電機的額定電流，PLC輸出給變頻器的信號是否正常，一切正常的話(huà)如果故障依然不能排除，請樓主對照電機數據把電動(dòng)機名牌上的參數輸入變頻器，然后再給變頻器運行一次自整定試試，要是還不行的話(huà)可能是變頻器有問(wèn)題，換一臺變頻器試試。
以上~~
