DP通訊控制變頻器運行時，在設(shè)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(shè)備出現(xiàn)故障時，變頻器脈沖封鎖，轉(zhuǎn)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(shè)為0，否則故障復位時設(shè)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(zhuǎn)速降為0后，再停止運行的。你可以放心。
