FANUC系统基于自诊断功能的参数故障分析与处理

Parameter Failure Analysis and Processing Based on Self-diagnosis Function for FANUC System

数控机床参数的正确性直接决定着数控机床的功能与性能;数控机床在使用过程中,难免会出现参数的丢失、错乱或者人为因素的破坏;这必然会导致机床无法正常运行;在出现类似故障时,要迅速准确查明故障的原因和部位,从而快速排除故障;分析了FANUC系统参数的具体形式和常见参数故障,灵活运用现代数控系统丰富和完善的自诊断功能;通过具体实例,给出了利用自诊断功能对参数故障进行检查、分析与排除的方法;这种方法不需要借助于诊断仪器,能够快捷有效地对参数故障进行诊断和处理,可以广泛应用在现代数控机床的维修中。

The correctness of the parameters directly decides the function and performance of NC machine tools.However,it is hard to avoid the loss of the parameters,confusion or the destruction of the human factors in practical use of NC machine tools.It will inevitably lead to the failure of normal operation.In this kind of failure,it need to find out the reason and the location of the fault rapidly and accurately,and rule out the fault quickly.The article analyze the specific form and basic operation of parameters for FANUC system and flexiblly use the rich and complete self-diagnosis function of the modern numerical control system.Through specific examples,the method using self-diagnosis function to inspect,analysize and eliminate the fault related to the parameters is gived.This method does not rely on diagnostic instrument,can diagnose and treat parameter fault quickly and effectively,and can be widely used in maintenance of modern NC machine tools.
