PLC和变频器在龙门刨床控制中的应用

The Application of the PLC and Inverter In the Planer Control

叙述了龙门刨床主拖动控制线路的控制要求及采用PLC和变频器进行改造设计的方法和步骤,给出PLC编程程序梯形图、变频器参数设置表。通过PLC和变频器对龙门刨床控制系统的改造,简化了原机床控制电路,节省大量的继电器元件,维修方便,使机床的工作效率更高.

Requirements of the main drag control circuit in planer and design methods and procedures with PLC and Inverter are introduced. Then the PLC ladder programming proce- dures and Inverter parameter settings are presented. Through Machine reconstruction with PLC and Inverter, driving control is move simplified than original machine tool control. A lot of relay components is saved and maintenance and check is easy. The machine works more efficiently.
