Control device failure and its troubleshooting methods. CNC system hardware failure. An industrial control machine is used as the main control, and the Spanish AFGOR system is used as the CNC part of the CNC profiling milling machine. When a new processing program is replaced with a new processing program after processing parts, it suddenly crashes. And there is no alarm. After forcibly shutting down and restarting the system, the self-test fails at this time, the host cannot be started, and a black screen appears on the Display at the same time. Check that the display is normal, the processing program is correct, and the graphics card replacement and memory failure still exist. After analysis and judgment, there may be a problem with the motherboard. After replacing a new motherboard, the host starts up normally and the machine tool runs normally.
CNC system software failure A machining center using FANUC-OM system, once the machining program cannot be executed normally, the tool change and axis (vertical direction) function is lost, the machine parameters are confused, and the 910 alarm occurs at the same time.
After checking the alarm in the maintenance manual, it indicates that the ARM memory board is faulty. In order to confirm whether the fault is caused by hardware or software, the following inspection steps are taken: a. First check that the voltage of the backup battery is normal; b. Record the system memory parameters and then clear them all; c. Use the RS-232 interface to backup the previous ones The machine parameter file is transferred into the system; after the machine parameter restoration is completed, the power is cut off and the machine is restarted, and everything returns to normal as a result. This failure is caused by the confusion of machine parameters. Main failure phenomenon and cause Failure category Failure phenomenon Failure cause work. The failure of the tool post system to index is mostly the motor damage.
