Methods of eliminating electrical faults in busbar machines

There may be some electrical faults during the use of the bus machine. Therefore, the analysis process of the bus machine electrical fault is also the troubleshooting process. Therefore, some common troubleshooting methods of the bus machine electrical fault.   1. Power supply: The power supply is the energy source for the normal operation of the maintenance system and the entire machine tool. Its failure or minor failure will cause data loss and cause downtime. The severe ones will destroy part or even all of the system. Western countries have sufficient power and high quality power grids, so the power supply design of their electrical systems is less considered. This is slightly insufficient for the power supply network with fluctuations and higher harmonics in my country, plus some man-made factors , It is inevitable that there will be failures caused by the power supply.   2. Position loop failure of CNC system    1. Position loop alarm. It may be that the position measurement loop is open; the measurement element is damaged; the interface signal established by the position control does not exist, etc.   2. The coordinate axis moves without a command. It may be that the drift is too large; the position loop or the speed loop is connected to a positive feedback; the feedback wiring is open; the measuring element is damaged.   3. The machine coordinate cannot find the zero point. It may be that the zero direction is far away from the zero point; the encoder is damaged or the wiring is open; the grating zero mark is shifted; the zero return deceleration switch fails.   Fourth, the dynamic characteristics of the machine tool deteriorate, the quality of workpiece processing decreases, and the machine tool even vibrates at a certain speed. One of the larger ones may be caused by excessive clearance of the mechanical transmission system or even serious wear or insufficient lubrication or even wear of the guide rail; for the electrical control system, it may be that the speed loop, position loop and related parameters are no longer well matched. The status should be re-adjusted after the mechanical failure is basically eliminated.   Five, occasional shutdown failure. There are two possible situations: one situation is that the problem in the related software design as mentioned above causes a shutdown failure under some specific operation and function operation combination. In general, the machine tool will be re-energized after the power is cut off. Disappear;    Another situation is caused by environmental conditions, such as strong interference (power grid or peripheral equipment), excessive temperature, excessive humidity, etc. Such environmental factors are often overlooked by people. For example, in the southern region, machine tools are placed in ordinary workshops or even near open doors, electrical cabinets are opened for a long time, and there are a lot of equipment that generates dust, metal chips or water mist nearby.   The above is the method of troubleshooting the bus machine that our company brings to you, can you understand? If there is anything you don’t know, please consult us!
