Logic analysis and inspection for PLC programs

Through the logic analysis of the PLC program, it is convenient to find out the location of the problem. For example, the diagnostic screen of the ANUNU-OT system, the T command in the ANUNU-7M system.

Checking the drive chain conditions Drive chain failures are often reflected when machining parts. For example, the positioning accuracy is not accurate, the backlash is too large, the machine tool is crawling, and the feed drive is not in place. When checking, it can be performed by manual function or manual matching. If the running error is small (0. 01-0, 05m), most of them are mechanical faults. If the error is large and disorder, it can be judged that the control part is faulty. . Common faults and troubleshooting methods for CNC machine tools From the application point of view, faults can be divided into machine tool control device faults and mechanical faults; from the overall aspect of the system, faults are classified into software faults and hardware faults.

Mechanical failure and its troubleshooting methods (1) System overload alarm XH Xi 16 CNC vertical machining center, the system is AFNuC-OM system, this machine often has overload alarm during processing, the alarm number is 434, the expression is the name axis ( In the vertical direction, the motor current is too large, the motor heats up, and the alarm stops after about 40 stops. (2) The size of the machined parts is unstable. A CNC turret lathe adopts the AFUNc-3T system. When machining parts, the radial size is often large and small. Check that the control system and the machining program are normal, then check the connection between the motor and the lead screw in the drive chain, and find that the motor coupling fastening screw is loose. In the case of no-load, especially load, the motor shaft and the lead screw may have relative motion. Because the semi-closed-loop control position detecting element is on the side of the turtle machine, the actual amount of rotation of the lead screw cannot be detected, resulting in dimensional instability. The problem is eliminated after tightening the motor coupling.
