Fault diagnosis method for electrical system of CNC vertical

返回列表 source:未知
1, visual inspection

To put it simply, it is to use the inspection of the senses. The fault site personnel are carefully asked about the process of the fault, the fault appearance and the fault consequences, and may be asked multiple times during the entire analysis and judgment process.

2, the instrument inspection method uses conventional electrical instruments

For each group of AC and DC power supply voltages, measure the relevant DC and pulse signals, and find possible faults. For example, use a multimeter to check the status of each power supply, and measure the relevant signal state measurement points set on some boards. Use an oscilloscope to observe the amplitude, phase, or even the relevant ripple signal. Use the PLC programmer to find the PLC program. The location and cause of the fault.

3. Numerical control vertical lathe signal and alarm indication analysis method

Hardware alarm indication This refers to various status and fault indicators on various electronic and electrical devices including numerical control system and servo system. Combined with the indicator status and corresponding function description, the indication content and the cause and troubleshooting method can be obtained. .

4, interface status check method

Modern CNC systems integrate PLCs in them, and CNC and PLC communicate with each other in a series of interface signals. Some faults are related to the error or loss of interface signals. Some of these interface signals can be displayed on the corresponding interface board and input/output board, and some can be displayed on the CRT screen by simple operation, and all interfaces The signal can be called up with the PLC programmer. For each group of AC and DC power supply voltages, measure the relevant DC and pulse signals, and find possible faults. example

5, parameter adjustment method

CNC vertical lathe CNC system, PLC and servo drive system are equipped with many modifiable parameters to meet the requirements of different machine tools and different working conditions. These parameters not only match the electrical system to the specific machine, but are also necessary to optimize the machine's functions.

6, spare parts replacement method

When the fault analysis results are concentrated on a certain printed circuit board, it is very difficult to implement the fault on a certain area or even a certain component due to the continuous expansion of the circuit integration. In order to reduce the downtime, the same is true. Under the condition of spare parts, you can replace the spare parts first, and then check the repair fault board. Pay attention to the following problems when replacing the spare parts board. Any replacement of spare parts must be carried out in the event of a power failure.

7. Cross-transposition method

When the faulty board is found or the faulty board cannot be determined and there is no spare part, the same or compatible two boards in the system can be interchanged and checked, for example, the exchange of the two coordinate command boards or servo boards can determine the fault board. Or the fault location. This cross-transposition method should pay special attention to not only the correct exchange of hardware wiring, but also a series of corresponding parameters exchange, otherwise it will not achieve the purpose, but will create new faults causing confusion of thinking, must be considered in advance , design a good software and hardware exchange program, and then exchange and check accurately.

8, special treatment

The numerical control system of today's CNC vertical lathes has entered the development stage of PC-based and open-ended, in which the software content is more and more abundant, there are system software, machine tool builder software, and even users' own software, due to software logic. Some of the inevitable problems in the design will make some fault states unrecognizable, such as crashes. For this kind of fault phenomenon, special measures can be taken to deal with it. For example, the whole machine is powered off, and then restarted after a pause, and sometimes the fault may be eliminated. Maintenance personnel can explore their laws or other effective methods in their long-term practice.

The troubleshooting of the electrical system of the CNC vertical lathe is a difficult project for many people. These basic troubleshooting knowledge hopes to deal with the small troubles in the process of using the machine.
