DP通訊控制變頻器運行時,在設備出現(xiàn)故障時,編寫程序是否需要先使變頻器的運行速度為0,然后再使變頻器停止運行即控制字的第0位為0.如果不按這個順序進行,變頻器是不是會燒元件呀。
答:設備出現(xiàn)故障時,變頻器脈沖封鎖,轉速會將為0,,但你在編這個程序時,為了安全,應該在變頻器報故障時,將速度給定設為0,否則故障復位時設備會啟動。
編寫程序是否需要先使變頻器的運行速度為0,然后再使變頻器停止運行即控制字的第0位為0.如果不按這個順序進行,變頻器是不是會燒元件呀——
不必這樣做。如果不按這個順序進行,變頻器是不是會燒元件的??刂谱值牡?位為0后,變頻器會自動轉速降為0后,再停止運行的。你可以放心。
