摘　　要：针对ETC3650数控车床的控制要求,提出基于华中数控HNC808T的控制方案。利用NCUC总线实现数控系统与HSV-160U交流伺服驱动、PLC模块的连接。匹配广数伺服电动机,采用BISS协议绝对位置检测完成了2个基本伺服轴的半闭环控制。通过PLC轴控模块10 V模拟接口,采用无传感器矢量控制方式控制WJ200日立变频器,驱动主轴。机床输入输出全部使用远程I/O。经实际运行考验,证明机床的数控改造取得了成功。In order to meet the requirement on ETC3650 lathe machine,the control scheme based on HNC808 T NC system is put forward. NCUC bus is applied for the feed servo drive and PLC modules. GSK servo motors with the absolute position encoder are equipped for semi close- loop control. The spindle is driven by WJ200 HITACHI inverter which is controlled by the vector control without sensor through 10 V analog interface of axis control module. The remote I / O is applied for the machine. The practical application shows that the CNC retrofit is successful.
