6、然后返回A点，停车20s装料，如此反复。3.2 运料小车控制系统的控制内容与要求3.2.1 运料小车的控制系统主回路运料小车由一台三相异步电动机拖动，电机正转，小车向左行，电机反转, 小向右行。电动机正反转主回路如图 3-1所示。i r ssr aplctor tl_o failtlI oaicto lmanagementsyst s and measures eSabihd by a n a rube of pagmatc combne d palseury a s rcuedir te a rnral irex Slim ir te ”ctor o te dy - m orrltuk ar

30、简单应用。将PLC应用到运料小车电气控制系统，可实现运料小车的自动化控制，降 低系统的运行费用。PLC运料小车电气控制系统具有连线简单，控制速度快， 精度高，可靠性和可维护性好，安装、维修和改造方便等优点。运料小车控制流程图如图3-4所小。maroe-erosr.podct o 一 nils atacirgpols-rigoce tL pe-e _urtoe eI .d Cisorayis ard sotcy O-osy e rhrced sclty lider ird sert r he lom a lgua lust epae te o d lp - ut.hi Iy wcuiyshol
