摘要
在对T68镗床的基本结构和控制要求进行分析后,选择了西门子公司的S7-200系列PLC,取代了原继电器-接触器控制电路,完成了控制系统的技术改造,经过调试满足实际生产要求。经过改造后的镗床控制系统硬件电路得到了简化,提高了机床工作的可靠性。
In the basic structure and the control of T68 boring machine requirements analysis, choose S7-200 series PLC Siemens company, instead of the original relay contactor control circuit, completed the technological transformation of control system, through debugging meet the requirements of production. After the system hardware circuit reliability of machine tool works. controlled by reconstruction is simplified, improves the
