摘　　要：西门子SINUMERIK 840D数控系统与SIMODRIVE 611D数字驱动模块可组成半闭环或全闭环伺服系统,利用功能块FB3可设定和修改机床数据,从而实现闭环与半闭环伺服系统的切换。通过对SINUMERIK 840D数控系统位置控制的分析,给出了运用功能块FB3实现位置测量系统转换的可编程逻辑控制器(PLC)程序。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 semiclosed 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.
