The self-diagnosis of the CNC system can not only display fault alarm information on the CRT display, but also provide machine parameters and status information in the form of multi-page "diagnosis address" and "diagnosis data". Common data and status checks include parameter check and There are two types of interface checks.
1) Parametrlarni tekshirish CNC dastgoh asboblarining dastgoh ma'lumotlari bir qator sinovlar va sozlashlardan so'ng olingan muhim parametrlar bo'lib, dastgohning normal ishlashi uchun kafolatdir. Ushbu ma'lumotlarga daromad, tezlashtirish, konturni kuzatish tolerantliklari, teskari tebranish kompensatsiyasi va qo'rg'oshin vinti qadamining kompensatsiyasi kiradi. Tashqi aralashuvga duchor bo'lganda, ma'lumotlar yo'qoladi yoki chalkashib ketadi va dastgoh normal ishlay olmaydi.
2) Interface check The input/output interface signals between the CNC system and the machine tool include the interface input/output signals between the CNC system and the PLC, and between the PLC and the machine tool. The input/output interface diagnosis of the CNC system can display the status of all switching signals on the CRT display, and use "1" or "0" to indicate the presence or absence of the signal. Using the status display, you can check whether the CNC system has output the signal to the machine tool. side, whether the switch signal on the machine tool side has been input to the CNC system, so that the fault can be located on the machine tool side or in the CNC system.
