Symptoms: A CNC vertical machining center supporting FANUC-0M system often has an overload alarm during processing. The alarm number is 434. The manifestation is that the Z axis motor current is too high, the motor heats, and the alarm disappears after about 40 minutes. Then the alarm disappears. After working for a while, similar alarms appeared again.
Analysis and treatment process: After checking the electrical servo system is not faulty, it is estimated that the load is too heavy to be fixed. In order to distinguish between an electrical fault and a mechanical fault, the Z-axis motor is removed and mechanically disengaged and the fault no longer occurs during operation. It was confirmed that the mechanical screw or the moving part is too tight. Adjust Z-axis screw locknut, the effect is not obvious, and later adjust the Z-axis guide rails, machine load significantly reduced, the failure to eliminate.
