Servo drive system maintenance
Model: ED514V
Failure phenomenon: AL-04 alarm
Fault analysis: according to the fault code prompt query for the intelligent fault module, measurement module was found to burn, found on V P measurement module in the short circuit, measuring the driving foot V phase short-circuit this phase rectifier diode to open circuit. Remove module to repair power supply. The replacement of rectifier diode and capacitor on electric power coupling, normal. Driving voltage is also normal. External plus trigger signal to measure the output waveform is normal. Replacing the new module on everything is normal.
Repair: the replacement of rectifier diode, optocoupler, capacitor, normal module.
