Servo motor maintenance
Model: ASD-A20721
Failure phenomenon: AL001 alarm (over current)
Fault analysis: according to the fault description for the customers to work just start spraying reciprocating machine appeared AL001 alarm from other devices installed on the same drive down OK, according to the description of the fault is recognised as servo drive failure. Open the case to check the power supply is normal. Measurement of the main circuit IGBT module U and P have a short circuit phenomenon. Remove the module to measure the driving voltage is normal. The initial suspicion is that the short circuit of the IGBT module leads to the failure of the AL001 fault. The replacement of the new module on the electrical test paper AL011 fault. Connect motor and encoder test everything to normal.
Fault repair: replacement of the new IGBT module fault repair.
