1. The large current causes the alarm of CNC cars. In general, there are two perhaps a large current alert. It is the output power of the core CNC machine tool to manipulate the output power on the module to promote the damage and short -circuit fault.
2. High voltage will also cause alarms of CNC cars. There are generally three possible situations that generate high -voltage alerts. Perhaps the processing voltage of the core CNC machine tool is higher than the rated value, or the insulation in the servo motor is exchanged. A decrease in action, or the high voltage caused by the processing rate of the module to manipulate the module.
3. The work voltage is too low to cause the alarm of CNC cars. The risk of processing the core of processing is to count the counting. This situation may be that the working voltage may be less than 85 % of the rated value, or the switching power supply is poorly connected. cause.
4. Chemical reaction lines that test efficiency are disconnected to cause alarm. This phenomenon is incorrect, because there is no problem with the airfield skills, and the inspection reflects that there are problems with the management system. Most of these alarms are the core CNC machine tools of the processing of processing The rate of AC servo motors reflects the line break or its inspection reflects the poor route contact.
5. Maintaining the operation alert operation of the power supply switch, maintaining the power supply switch is a device that maintains the number of lathes to maintain CNC lathes. For example, the large working voltage will damage some components such as some components. In the process, maintaining the power switch will run to prevent many unnecessary parts from destroying, similar to security interruptions.
6. Load alarm, due to the production of load alerts, there is an abnormal load of the processing core CNC device, or the upper limit value of the motor volume on the power manipulating module is too low. The permanent magnetic field on the permanent magnet motor will also cause a load alarm. If the motor of the core CNC machine tool does not have a brake system, it cannot be turned around or the driving shaft is very laborious, which means that the permanent magnetic is completely falling.
7. Machining the core CNC machine tool The melting wire burning on the module or cutting the circuit breaker.
