FANUC Feed Servo System Common Fault Analysis
Feed servo system is one of the most important components of CNC system and plays a decisive role in machining accuracy and surface roughness of workpiece. FANUC feed servo system is the most widely used system in CNC vertices. This article will analyze the common faults of FANUC feed servo system and propose the appropriate rectification methods.
First of all, short-circuit failure is a common fault of FANUC feed servo system. This kind of fault is due to the fact that more than two lines close to each other, so that the normally open line is closed, which causes a short circuit, resulting in the failure of the drive system.
The rectification method for this kind of fault is usually to rectify the wiring of the line, and check whether the wiring of the drive system conforms to the wiring rule. Make sure that all the line positions are correct and whether the line is too crowded.
The second kind of common faults is the failure of the drive itself. This failure is due to the dust in the internal canister, resulting in the insulation surface of the device being contaminated and the short circuit of the coil.
In this case, the solution is to clean the dust in the canister thoroughly and replace the damaged electrical components. In addition, the fan of the cabinet should also be adjusted to ensure enough air flow, so that the running temperature of the drive itself is in a reasonable range.
The third common fault is overload. This kind of fault is due to the fact that the load is too large, resulting in the overvoltage of the drive, resulting in the incapability of the drive itself. The rectification method of this fault is to adjust the load capacity of the drive system so that it is sufficient to ensure the regular operation of the drive.
Finally, the common faults of FANUC feed servo system are lack of electricity and poor emergency. In this case, the solution is to check whether there is a lack of power supply in the external power supply, and to check whether the emergency circuit of the machine tool is intact. If the emergency of the machine tool is poor, it needs to be adjusted to ensure the smooth operation of the machine tool.
In summary, FANUC feed servo system is one of the most important elements of CNC system. Any failure of the system will cause great losses. Therefore, it is necessary to analyze the common faults of FANUC feed servo system and propose efficient rectification methods to ensure the normal operation of the whole system.
