描述
自控系統(tǒng)的設(shè)定信號可通過變頻器靈活自如地指揮頻率變化,控制工藝指標(biāo),如在煙草行業(yè)的糖料、香料工序,可由皮帶稱的流量信號來控制變頻器頻率,使泵的轉(zhuǎn)速隨流量信號自動變化,調(diào)節(jié)加料量,均勻地加入香精、糖料。也可利用生產(chǎn)線起停信號通過正、反端子控制變頻器的起、停及正、反轉(zhuǎn),成為自動流水線的一部分。此外在流水生產(chǎn)線上,當(dāng)前方設(shè)備有故障時後方設(shè)備應(yīng)自動停機。變頻器的緊急停止端可以實現(xiàn)這一功能。在SANKEN、MF、FUT和FVT系列變頻器中可以預(yù)先設(shè)定三四個甚至多達七個頻率,在有些設(shè)備上可據(jù)此設(shè)置自動生產(chǎn)流程。設(shè)定好工作頻率及時間後,變頻器可使電機按順序在不同的
