When the full set of equipment can not operate when dimensional movement mixer inverter 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. First, the more common of the two-dimensional movement mixer drive repair the fault: 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. With load shutdown at 8888: inverter 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 inverter: the original fault bombing run no output or E019 repair the often bad U9. No output Q2 is also sometimes bad. Small power inverter: 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. Second, the generic type of inverter dimensional movement mixer converter repair applications is really not only speed range with some kind of equipment, it is widely used in paper, textile, printing machinery, steel strip, film, painting equipment , high precision the need 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 control field; engineering machinery, wire drawing machine, squeeze presses, transmission equipment, such as the need for high-speed operation, a high starting torque and position control of the machine control area. Converter repair work non-dimensional movement mixer on top several common knowledge, the accumulation of experience, or need long-term practice. Yung economic technicians can also be consulted for more resources.
