Roest servo driver maintenance
Failure phenomenon: boot without display
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. But the main board HC04, 751168 high temperature, less than 2 minutes and power burned, the motherboard has short circuit, to check that the U12 chip has short circuit board, after the replacement of the power after the restoration of electricity normally for a long time. On the computer link test everything is normal. This fault is mainly the main board short circuit and the output level short circuit causes the power fault. The earliest people replaced the rectifier and power supply.
Jiahong maintenance Weilusite servo driver, servo driver maintenance, servo controller, driver module, common fault repair roest servo driver: no display, lack of phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display no damage, error; Hong Jia Wei complete accessories, professional maintenance engineers, detected by the test software with servo motor testing to ensure the quality of maintenance. Professional maintenance, module deep fried, the output voltage is low, the red light is bright, no show, lack of phase, accessories complete, the price is reasonable.
