順序控制電路分析

1、順序控制電路分析1 順序控制線路 在裝有多臺(tái)電動(dòng)機(jī)的生產(chǎn)機(jī)械上，各電動(dòng)機(jī)所起的作用是不同的，有時(shí)需按一定的順序啟動(dòng)或停止，才能保證操作過程的合理和工作的安全可靠。 2主電路實(shí)現(xiàn)順序控制M13L1L2L3FU1FU2KM1KM2KH1KH2SB1SB2SB3KM1KM2KM1KM2KH1UVWQSKH2M233L1L2L3FU1FU2KM1KM2KH1KH2SB1SB2SB3KM1KM2KM1KM2KH1UVWQS合上電源開關(guān)QSM13M23KH2主電路實(shí)現(xiàn)順序控制4L1L2L3FU1FU2KM1KM2KH1KH2SB1SB2SB3KM1KM2KM1KM2KH1UVWQS只能先按下SB1M13M
