numerical control machine Sometimes, it is inevitable to have a failure. What is the matter? Basically, it can be divided into two categories:

The first is due to NC The problem of machine parameters in the system (sometimes due to improper settings, sometimes due to unexpected changes or confusion) caused by the parameters, for this kind of soft fault, as long as the parameters are adjusted properly, the fault will disappear naturally. ¡¡¡¡

The second kind of soft fault is usually caused by accidental reasons NC Generated when the system is in a dead loop state. For this kind of fault, the system can be recovered by forced reset and restart.

In order to make it easier for you to understand, we will explain it through two examples

¡¡¡¡ one , one FANUC-OT The CNC lathe of the system, every time the CNC machine tool starts up, the phenomenon of machine crash occurs, any command can not operate normally. After the system memory is cleared to zero, the system returns to normal. After inputting the parameters and programs of the machine tool again, the machine tool can be used normally. This fault is caused by the confusion of machine parameters. ¡¡¡¡

¡¡¡¡ two In the CNC system of Siemens, the alarm is displayed on a CNC machine¡° LIMITSWITCH ¡±This kind of failure is caused by Y If the shaft stroke exceeds the limit value set by the software, check that the program value does not change. After careful observation of the fault phenomenon, when there is a fault, the Y After carefully adjusting the software input limit value, it is found that the software input limit value is adjusted properly. This fault is caused by improper setting of software limit parameters of CNC machine tools.
