CNC machine tool machining center is an automatic machine tool product composed of mechanical equipment and CNC system that can process complex parts. The CNC machining center will encounter some problems in daily use. This is the process we usually use for CNC machining centers. Not only should we pay attention to maintenance, but also need to pay attention to the operation of the CNC machining center. Do not operate blindly. The following are some of the failures of the CNC machining center in daily use and some of the failures of the CNC machining center. Simple Analysis.
1. The problem of encoder pulse counting error alarm of CNC machine tool machining center
This type of problem is usually displayed on the LED display 6, and the PMM screen in the system screen displays 303/304/305/308 alarm. The main reason is that the serial encoder of the servo motor does not calculate the number during operation or it is caused by the pulse loss This kind of phenomenon needs to be turned on after shutdown, 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 sound disappears, it is not too happy. We need to return to the CNC machining center. After the reference point, run other commands to debug, the weak PMM308 alarm may be caused by interference, just turn off and on
2. CNC machining center machining center serial encoder communication error alarm
For this kind of problem, we should first check the connection accuracy or disconnection of the encoder amplifier of the CNC motor of the CNC machine tool machining center and the feedback line. If the shield of the motor feedback line is not intact, please go to the manufacturer's warranty as soon as possible. In CNC machining, the encoder of the motor is connected with the motor, it is best not to disassemble.
