Example 1: A CNC machine tool adopting SINUMERIKSYSTEM3 from Germany Siemens, its PLC adopts S5─130W/B, and a failure occurs. The R parameter input through the PC function of the NC system does not work during processing, and the R parameter in the processing program cannot be changed. The value of. Through the analysis of the working principle and failure phenomenon of the NC system, we believe that there is a problem with the PLC main board. After swapping with the main board of another machine tool, it is further determined to be the problem with the PLC main board. After repair by professional manufacturers, the fault was eliminated.

 

 

Example 2: Another machine tool also uses the SINUMERIKSYSTEM3 numerical control system, and its processing program program number cannot be entered, and automatic processing cannot be performed. It was confirmed that there was a problem with the NC system memory board. After repair, the fault was eliminated.
