YASKAWA drive maintenance
Model: SGDM-08AD
Fault phenomenon: reported current fault
Fault analysis: This is the old Yaskawa server, according to the fault measurement module of IGBT V drive power to remove short circuit, electrical measuring voltage V module not normal. The detection of V phase rectifier diode and a voltage stabilizing tube to burn, after the replacement of measuring voltage in normal, the new module installed after the encoder fault test report. After the motor is connected to the lifting of the fault.
Fault repair: replace the V phase power supply voltage regulator tube, diode, after the module is all normal.
Hong Jia Wei maintenance YASKAWA Yaskawa server maintenance without display, lack of phase, overcurrent, overvoltage, undervoltage, overheating, overload, grounding, parameter error, output module, display without damage, error, Yaskawa server maintenance models: SGDA, SGDB, SGDV, SGDM, SGDS, SGDP, CACR etc..
