What are the reasons why vertical machining centers generate alarms after the spindle is overloaded?
More and more machines are used in life, and there are often situations where machines cannot be separated. CNC vertical machining center is a titanium cnc machining process testing instrument used in the field of mechanical engineering. Vertical machining centers are widely used CNC machine tool processing equipment in the market. Although they have many advantages, they may also encounter some malfunctions during use. For example, after the spindle is overloaded, the machining center will generate an alarm. Usually the alarm number is It is 751. If the alarm number of the spindle servo module is AL-73, then what is the specific reason why the vertical machining center generates this alarm? This article will conduct a simple analysis next.
Vertical machining center alarms after the spindle is overloaded can usually be divided into three situations. One is the alarm occurs when the motor excitation is turned off. In this case, there are the following reasons, such as errors in parameter setting. , at this time it is necessary to confirm whether the setting parameters of the sensor are correct; if the cable is disconnected, it will also cause this alarm condition, and the cable needs to be replaced at this time. If there is a failure in sensor adjustment, the sensor signal needs to be adjusted accordingly. If there is really no way to adjust, the connected cable or sensor should be replaced.
The second situation in which an alarm occurs after the spindle of a vertical machining center is overloaded is when the spindle is running or when the cable is touched. The reason for this may be that the wire is broken. At this time, the cable should be replaced. If cutting is found If oil invades the connector part, the user needs to clean it in time.
In the latter case, an alarm occurs when the motor rotates. The main cause of this situation is a fault in the cable shielding between the sensor and the SPM. At this time, the metal jewelry manufacturers and cable shielding needs to be confirmed. It is also possible that the cable between the sensor and SPM and the power line of the servo motor are tied together. In this case, they need to be tied separately.
