The study of principal axis controller in open CNC system

The research of open numerical control, which is used PLC and the frequency converter in order to carry out counter-rotating and viable speed, is adopted the imbedding open numerical control. The IPC, as the platform of the open numerical, can make the utmost of the software and hardware resource of the computer and the latest development result. The mechanical structure of spindelantrieb can be into simplification which can handily control the counter-rotating of the spindle and realize a wide-range stepless regulation with regard to the study of open numerical control.
