Brief Analysis of CNC Machining Center Working Faults


Author: MULAN -Plastic Molding Manufacturer

CNC machining center is an automatic machine tool product composed of mechanical equipment and numerical control system that can process complex parts. CNC machining centers occasionally encounter some problems in daily use. In our daily use of CNC machining centers, we not only need to pay attention to maintenance, but also need to pay attention to operating according to the rules of CNC machining centers. Do not operate blindly. The following lists some faults and a simple analysis of the faults in the daily use of CNC machining centers.

CNC machining center encoder pulse count error alarm problem This kind of problem usually displays 6 on the LED display screen, and 303/304/305/308 alarm is displayed on the PMM screen in the system screen. The main cause of the fault is that the serial encoder of the servo motor is running. It is caused by not counting numbers or pulse loss. This kind of phenomenon needs to be turned off and then turned on, and the alarm will often disappear. If there is still an alarm, the motor or feedback cable should be replaced immediately, but if the alarm disappears, it is not too much. Happy, we need to run other commands for debugging after returning to the reference point of the CNC machining center. The weak PMM308 alarm may be caused by interference, just turn it off and turn it on again. CNC machining center serial encoder communication error alarm For this kind of problem, we should first check the encoder amplifier of the CNC machining center CNC motor and the connection accuracy of the feedback line or whether there is disconnection. If there is shielding of the motor feedback line If it is not in good condition, please go to the manufacturer for warranty as soon as possible. Usually, the encoder of the motor is integrated with the motor in CNC machining, so try not to disassemble it. The above is for reference only, and I hope it will be helpful to friends in the industry.
