Transform of Location Test Systems Based on Variables Access Function
Wang Kanfu · Journal of Shanghai Dianji University · 2011
Both closed and semi-closed servo system can be obtained from data control elements of SIMENSE SINUMERIK 840D and SIMODRIVE 611D.The FB3 function elements can assign and revise machine data,and thus realize transform between closed servo systems and semi-closed servo systems.In this paper,by analyzing location control of the SINUMERIK 840D data control system,the above transform approach is studied,and a programmable logic controller(PLC) program is presented.
