The numerical control device control system fault mainly uses the self-diagnosis function alarm number, the information status indicator of each board of the computer, the waveform and voltage value of each key test point, the adjustment of each relevant potentiometer, the setting of each short-circuit pin, and the relevant machine tool parameter value. The settings, special diagnostic components, and reference to the control system maintenance manual, electrical atlas, etc. are excluded. Common faults in the control system and their diagnosis are as follows. (1) CNC machine tool battery alarm failure. When the CNC machine is powered off, in order to save the machine parameters and machining procedures of the machine control system, it is necessary to support the backup battery. When these batteries reach the end of their useful life, that is, when their voltage is lower than the allowable value, a battery failure alarm is generated. When the alarm light is on, it should be replaced in time. Otherwise, the machine parameters are easily lost. Because of changing or replacing. If the results are not effective or the buttons used do not work, you can further check the interface circuit, system control software and cable connection status of this part. (2) CNC machine tool keyboard failure. When using the keyboard to input the program, if it is found that the characters cannot be input, cannot be eliminated, the program cannot be reset, or the display cannot change the page, etc., first consider whether the button is not in good contact, and the well is repaired or replaced. If the results are not effective or the buttons used do not work, you can further check the interface circuit, system control software and cable connection status of this part. (3) Fuse failure of CNC machine tools. The fault of the fuse blown in the control system occurs mostly in the case of misoperation of the measurement of the numerical control system or accidents such as a collision of the machine tool. Therefore, maintenance personnel should be familiar with the protection range of each fuse so that it can be detected and replaced in case of problems. (4) Change of tool position parameters of CNC machine tools. Once the tool position is found to be incorrect, check whether the tool location number of the control system matches the actual tool post position. If it does not match, refer to the method described in the manual to change the tool position number in the control system memory to the position of the tool post in time. Consistent. (5) "NOTREADY" fault of the CNC machine control system. 1 First check whether there are other fault indicators on the CRT display panel and the fault information prompts. If there is any problem, it should be solved according to the prompt of the fault information catalog. 2 Check whether the servo system power supply device has fuse disconnection, circuit breaker trip, etc. If the circuit breaker is tripped after closing or replacing the fuse, check whether there is any problem in the power supply part; check whether there is motor overheating, high power transistor The fault of the component overcurrent causes the computer monitoring circuit to function; check whether the faulty light is displayed on each board of the control system. 3 Check whether the voltage values ​​of the AC power and DC power supplies required by the control system are normal. If the voltage is not normal, it can also cause logic confusion and cause a "NOTREADY" fault. (6) Modification of machine tool parameters. For each CNC machine tool, it is necessary to fully understand the meaning and function of each machine tool parameter. In addition to helping the operator to understand the performance of the machine tool well, it is also beneficial to improve the working efficiency of the machine tool or to solve the problem. There are many faults in the control system, such as: insufficient brightness of the CRT display device; no frame synchronization, no display; failure of the optical reader; input and output printer failure. As for the complete elimination method of the machine parameters, the initialization method of the numerical control device, the replacement method of the spare board, and the precautions, the method is different depending on the system, which requires specific analysis according to the specific situation, refer to the relevant maintenance information and individuals. Work experience is resolved.
