Principle analysis method: Based on the composition principle of the CNC system, the logical levels and characteristics parameters (such as voltage values or waveforms) of each point can be analyzed logically, and then measured, analyzed, and compared with a multimeter, logic pen, oscilloscope, or logic analyzer to find the fault. Spare board replacement method: use spare circuit boards to replace templates with suspected errors is a fast and simple way to determine the cause of errors.

Measurement comparison method: for the convenience of detection, modules or units are equipped with detection terminals. Instruments such as multimeters and oscilloscopes are used to detect the level or waveform through these terminals. The normal value is compared with the value at the time of the error to analyze the cause and location of the error. ???? ???? ????: ?? ????? ????? ???? ???? ??? ??? ??? ??? ??. ??? ?????? ???? ?? ?? ???? ????? ?? ????? ????? ?? ???? ?????? ??? ???? ??????? ????? ?????? ??? ????? ????? ????? ????? ?? ???? ??? ?????? ?? ????? ?????? ???? ??. ??? ????? ???? ?? ??? ???? ???? ?? ????? ?? ?? ????? ????? ?? ?????? ??? ????? ???? ?? ?????? ??? ????? ????? ?? ???? ??? ??????? ???? ?????? ??????: ?????? ?????? ?? ?? ?? ????? ????? ?? ??????? ??? ???????? ?? ????? ???? ??. ?? ????? ???? ?????? ?? ??? ????? ?????? ??????? ?? ???? ????? ????? ?? ???? ?????? ???? ??? ????? ???? ????? ???? ?? ???? ????? ??? ???. ??? ??? ???? ?????? ??? ???? ?????? ???? ?????? ????? ?????? ?????? ???? ??? ???. ?????? ??????: ??? ???? ??? ???? ?????? ?? ?????? ???? ???? ?? ???? ????? ????? ??? ?????? ?????? ?? ?????? ?? ???? ?????. ?? ??? ???? ????? ????? ?? ???? ??? ????? ?? ??? ??? ???? ??? ??? ?? ??? ??? ?????? ?? ????? ?????. ??? ???? ????? ????? ?? ????? ?? ?????? ??? ????? ??? ????? ??? ???? ???? ??????
