摘要
介绍了Allen Bradley公司 1747 L40C型可编程程序控制器在振打电机控制中的应用 ,分析了振打电机的工作过程及时序图 ,给出了硬件接线图及程序设计框图。将第一电场的振打时序作为后续电场时序控制的基准 ,从而避免了定时器累积误差所造成各电场之间的逻辑关系错误 ,并在实际应用中取得了良好的效果。
This paper introduced the application of the type 1747 L40C PLC in the rapping motor control and analyzed the operating principle and timing diagrams. The wiring diagram and the flowchart were also given. At the first time, the rapping sequence of the first electric field is used for the timing reference, so the right logic rapping relations between the electric fields are continuously maintained.
