Xinje servo drive repair
Failure phenomenon: customer response through the display of E-007 (over current) alarm
Fault analysis: U, V, check the W connection, see whether the reverse phase; resistance measurement of the motor, see the white resistance is not balanced; this is the normal use is no problem. Check the encoder, the servo driver to U-10, slowly by hand to loosen the motor shaft, see the U-10 value change is normal, incremental decline in one direction, a direction (0-9999 cycle); the normal. U, V, W, PE and are short circuit; the results of U and N have short circuit phenomenon.
Fault repair: replacement of IGBT phase U tube by the power of the normal test.
Hong Jia Wei xinje servo driver maintenance professional maintenance, servo motor maintenance, fault repair can drive: no display, xinje phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display no damage, error; Jia Hong Wei accessories complete, professional engineer maintenance, testing through 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.
