Mainly pulling adopts and regards enlarger of the electrical machinery as the direct current generator of the excitation regulator-motor system of this double housing planer,because the working bench works in apply-brake-reverse reciprocating the motion state, high control requirement,and the maintenance inconvenience of direct current machine, it is very difficult to use the system to meet the control requests. The device uses electrical control relay to control circuit, using a large number of intermediate relay and time relay resulted in large, complex circuits, relays the high incidence of failure, poor reliability, and maintenance workload. Adopt Mitsubishi FX2N-80MR programmable controller and Emerson TD2000 inverter to implement the tranformation to the double housing planer. Mitsubishi PLC finishes the collection of the data and task of control on apparatus such as frequency converter, electrical machinery in the system. The software GX Developer8.0 of programming based on FX2N PLC adopts the module procedure design method, uses a large number code reuse, reduces software development and maintenance.
