Kuhn QUIN drive repair
Model: LINQ4218230V
Fault: communication failure
Fault analysis: the customer brought by other maintenance personnel repaired, open the shell detection module and the driving circuit is normal, static measurements show that the switching power supply has obvious fault, short circuit and output diode IC measurement replacement after electrical measurement found normal voltage. On the computer link test everything is normal. This failure is mainly due to the output level short circuit fault. The earliest people had to replace the rectifier. This driver is the earliest failure of the power supply fault module, is now after the customer is said to be linked to the host computer communication failure, this drive for the printer specific drive, according to the fault measurement power supply voltage is normal. Connecting the computer test communications is not normal. After a long time to check the motherboard communication circuit is found to have a IC waveform is not normal. After changing the test on line communication is normal.
Jia Hong Wei repair can repair the common failure of Kuhn QUIN drive: no show, lack of phase, over current, over voltage, under pressure, overheating, overload, communication, parameter errors, there is no output display, module damage, etc..
