When the full set of equipment can not operate when the plastic ladder ring servo maintenance and inspection work can not be ignored. Yung economic electromechanical technicians in addition to quickly resolve problems on the factory floor, the Remote Assistance Similarly, their strengths. A more common plastic ladder ring servo repair failure: 1, machine hiccup: that is faster or slower when the fan, no display. General control panel short circuit, remove the control panel and then power-on, such as hiccups may be thick-film device around bad. 2, the fan weakness, slow speed: the drive circuit breakdown. On telegraph 8888: FECDF21U1 board U8 bad, there is a small crack. Load downtime reported 8888: Server inductance quantitative difference or the PC9 former Vice edge of insulation is not enough. Run newspaper in 8888: drive optocoupler short circuit. 4, the high-power servers: the original fault bombing run no output or E019 repair the often bad U9. No output Q2 is also sometimes bad. 5, low-power servers: the original fault bombing, repair power no output, often bad R13. Repair bombing is to make a habit of measuring R13 whether 10 European, or other parameters. Plastic ladder ring servo repair applications Universal type server it is not only with some kind of equipment, it is widely used in paper, textile, printing machinery, steel strip, film, painting equipment speed range, accuracy high, tension control process control field; elevators, cranes, promotion, parking equipment, or three-dimensional garage need high-speed operation, high starting torque and position control, the promotion of the control field; construction machinery, wire drawing machine, extruder transmission equipment requires high-speed operation, a high starting torque and position control the field of machine control. Common the plastic ladder on top of ring the servo repair work non knowledge, experience the accumulation or need long-term practice. Yung economic technicians can also be consulted for more resources.
