Busbar Processing Machine Electrical Troubleshooting Solutions
1. Power Supply: The power supply is the energy source that maintains the normal operation of the system and even the entire machine tool. Its failure or malfunction can result in data loss, downtime, and even partial or complete system damage. Western countries enjoy abundant electricity and high-quality power grids, so their electrical system power supply design is less considered. This is insufficient for my country's power supply network, which is subject to high fluctuations and harmonics. Add to this the fact that power supply problems can inevitably lead to failures.
2. CNC System Position Loop Failure
1. Position loop alarm. This could be caused by a position measurement circuit break, a damaged measuring element, or the absence of the interface signal establishing position control.
2. Axis movement without command. Possible causes: Excessive drift; positive feedback connected to the position or velocity loop; a feedback wiring break; or a damaged measuring element.
3. The machine tool coordinates cannot find their zero point. This could be caused by: the zero position direction being too far from the zero point; a damaged encoder or wiring break; a shifted grating zero mark; or a malfunctioning zero return deceleration switch. 4. The dynamic characteristics of copper busbar machine tools deteriorate, reducing workpiece machining quality and even causing vibration at certain speeds. A major cause may be excessive clearance in the mechanical transmission system, severe guideway wear, insufficient lubrication, or even wear. For electrical control systems, this could be due to the speed loop, position loop, and related parameters no longer being optimally matched. Optimization should be performed after the mechanical fault has been largely eliminated.
5. Occasional shutdown failures. This can occur in two ways: One is due to software design issues, as described above, leading to shutdown failures under certain specific operations and function combinations. Generally, the fault disappears after the machine tool is powered off. The other is due to environmental conditions, such as strong interference (from the power grid or peripheral equipment), high temperatures, or high humidity. These environmental factors are often overlooked. For example, in southern China, machine tools are often placed in ordinary factory buildings, even near open doors. Electrical control cabinets are often left open, near numerous devices that generate dust, metal shavings, or water mist.
