Four manifestations of electrical failure of precision CNC machine tools
Generally, if the precision CNC machine tools are faulty, you can use the alarm number of the machine self-diagnostic function to remind you. You can also refer to the ladder diagram or check the signal status of the i / o interface. , Data, troubleshooting flowcharts and adjustment methods, so as to combine the experience of the staff to carry out inspections.
Generally, this kind of fault can use the alarm number of the self-diagnostic function of the precision CNC machine tools, the information status indicators of the computer and the servo amplifier driver board, and the fault alarm indicator. The parameters and settings of the computer, servo amplifier board, the setting of the short-circuit pin and the adjustment of its related potentiometer, and the replacement of the function-compatible board or spare board are used for diagnosis and troubleshooting.
Failure of the precision CNC machine tools computer department. Generally, this kind of failure mainly uses the alarm number of the computer self-diagnostic function, the information status indicator on each board of the computer, the waveform and voltage value of each hub test point, the adjustment of various potentiometers, the setting of short-circuit pins, and the relevant machine tool parameters. Value setting, special diagnostic components, and refer to the computer control system maintenance manual, electrical diagrams, etc. for diagnosis and exclusion.
The AC spindle control system is malfunctioning. When the AC spindle control system fails, first understand whether the operator has accidentally operated inconsistent with the operating procedures, whether the power voltage has been transiently abnormal, and perform visual inspections to check for short-circuiter trips and fuse disconnections. failure. If not, reconfirm that it is an alarm display type fault. It is still an alarm display type fault.
