摘要
数控机床的PLC故障大多数出现在电气线路或者电气元件上,快速诊断和排除其PLC故障可以确保生产率。以基于西门子802C数控系统的数控机床为例,分析了数控机床用PLC的信号传递方式,阐述了数控机床PLC故障诊断与排除的方法和流程。通过实际案例的剖析,总结了快速诊断与排除数控机床PLC故障的方法和机床维修人员所需具备的能力。该方法也为其他数控机床PLC故障的诊断与排除提供借鉴和经验。
The vast majority of PLC failures of the CNC machine tools occur on the input or output interface circuits or their electrical components. Productivity can be ensured through rapid diagnosis and troubleshooting. Take Sinumerik 802 C CNC as an example,this paper analyzes the role of signal transmission of PLC used in CNC machine tools,expounds the fault diagnosis and elimination method and process of it. The methods of fast fault diagnosis and eliminate of PLC and the ability of maintenance personnel needed are summarized through the actual case. The methods can provide reference for PLC fault diagnosis and eliminate of other CNC machine tools.
