Abstract: Have mainly illustrated the rebuilding of the conventional Longmen planer electricity control system(that is electric machine enlarger and electric generator and electric motor group) on the application of the modern frequency conversion and PLC software logic control technique. Thus, the rebuilding can obviously reduce its possibility of trouble and power loss in order to improve its control accuracy and machining quality.
