在现有回路的基础上,提出了一种新的、用于实现动力滑台运动的二流量阀并联的两工进速度换接回路,给出了其组成图和工作原理;采用FX2N32MR型PLC设计了其控制系统,得出了新回路及其控制系统的特点,展现了PLC在工业控制领域的广阔应用前景。
On the basis of the existing circuit, a new two-speed switchover circuit connected in parallel with the two-flow valve used to realize the power slide movement is proposed. The composition diagram and working principle are given. The FX2N32MR PLC Designed its control system, obtained the characteristics of the new circuit and its control system, and demonstrated the broad application prospect of PLC in the field of industrial control.
