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）パラメータ検査CNC工作機械の工作機械データは、一連のテストと調整の後に得られる重要なパラメータであり、工作機械の正常な動作を保証するものです。 これらのデータには、ゲイン、加速度、輪郭監視公差、バックラッシュ補正、送りねじピッチ補正が含まれます。 外部干渉を受けると、データが失われたり混乱したりして、工作機械が正常に動作しなくなります。
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.
