順序控制電路分析

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