Failure of the module or absolute encoder. Then the C axis and the C10 axis drive module and control module are swapped and restarted, and the fault still exists. Prove that there is no problem with the drive module and the control module. The reason may be that it is on the absolute encoder. In order to replace the C10 axis absolute encoder, the drive mechanism of the C10 shaft must be readjusted to meet the absolute encoder installation conditions. First, the mechanical brake is opened by short-circuiting to open the brake, the jack is used to hold the ram, and then the electric brake of the C-axis is opened by the short-circuit method. The machine starts, and the ram is adjusted with the jack to make the motor shaft and the encoder The connection matches the installation location. Install a new encoder, restore the original state of the machine, restart, and troubleshoot. Cooling water failure phenomenon There is no cooling water. After a few seconds of cooling water, the following alarms appear; the pump motor is processed during the process, the motor works normally, the pipeline near the first stage filter is warm, near the second stage filter The pipeline is cool. It is judged that the first-stage filter is blocked. After the removal, the filter core is found to be dirty and sloppy, and replaced. After the replacement, the cooling water is only a little bit of water. After analysis, it is considered that there may be a blockage of the cooling water pipe on the milling head. After the cooling water switch is turned on, another cooling motor is forced to turn, and the cooling water is sprayed out. . The installation angle difference of the accessory is 90. The alarm occurs after the C-axis rotation angle. After the recovery, the C-axis angle differs by 90° when the milling head is automatically loaded and unloaded. The processing method rotates the accessory milling head by the manual movement method or the manual power-off method to the position of the unloading head, relaxes the C-axis, forcibly unloads the milling head, and completes with a red signal indication. Power on the bed, restart, find the machine reference point, automatically install the milling head, and rotate the C axis 90°. After the execution, manually rotate the C axis to the position where the milling head is automatically installed, start the power failure, find the reference point, direct the spindle, automatically install the accessory milling head, and everything will return to normal. Conclusion CNC machine tools are high, precise and pointed equipment. The troubleshooting must follow certain rules. Maintenance personnel should be proficient in the control principle and sequence of the machine, and should have comprehensive knowledge of automatic control and mechanical and hydraulic aspects. The combination of machine, electricity and liquid phase can smoothly eliminate mechanical failures, speed up the maintenance schedule, improve the utilization rate of CNC machine tools, and make CNC machine tools fully effective. The axis appears to drive the alarm. The machine stops automatically when the machine is in the normal automatic program. The C10 axis drive alarm occurs and cannot be eliminated by the reset method. The machine has lost power and the alarm still exists when restarting. The processing method firstly adjusts the position loop cable of the C axis and the C10 axis, restarts, and the alarm still exists, which proves that the C10 axis position loop cable is not faulty, and may be the drive module.
