During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as adjustment welding mode error, pilot arc control exception, plasma unit or servo wire feed control exception, the teach pendant will usually display a hardware and control-level alarm in the 5103 to 5114 range. If these faults are not investigated promptly, they may cause serious operational safety hazards or damage to core components such as the reducer.
To help on-site engineers and mechanics quickly locate problems, we have organized the diagnostic terminology from the official maintenance manual to provide you with the following intuitive fault quick reference table. We recommend using the search function, entering the error code (e.g., 5103), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (5103-5114)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 5103 | Adjustment Welding Mode Point Error | The welding mode of the AS function is different from the welding mode of the adjustment target. | Check the welding mode to be adjusted, and then execute an exception reset. |
| 5104 | Pilot Arc Start Exception | Pilot arc was not closed. | Check the cable connection status, and restarting regeneration can eliminate the fault. |
| 5105 | Plasma Unit Exception | An exception occurred in the plasma fine unit. | Refer to the plasma fine unit manual, eliminate the exception, and then reset the fault. |
| 5106 | Pilot Arc Extinguish Exception | Pilot arc extinguished. | Check the cable connection status, and restarting regeneration can eliminate the fault. |
| 5107 | Pilot Arc OFF Exception | Cannot turn off the pilot arc. | Check the cable connection status, and then reset the fault. |
| 5108 | Pilot Arc ON Exception | Because cleaning is turned on, the pilot arc cannot be turned on. | Turn off cleaning, and then reset the fault. |
| 5109 | Servo Wire Feed Control Unit Exception | An exception occurred in the servo wire feed control unit. | Refer to the servo wire feed control unit manual to eliminate the cause of the problem, and then reset the fault. |
| 5110 | Retract Operation Execution Time Exceeded 10 Seconds | To protect the auxiliary feeding device, the retract operation was stopped. | If there are many retract procedures, choose to execute after 90 seconds, and then reset the fault. |
| 5113 | Cannot Set WCR Input Signal | WCR input signal is not assigned. | Assign the WCR input signal, and then reset the fault. |
| 5114 | Arc Welding Unit Setting Exception | Two or more welding machine units are registered, and welding cannot be executed. | Change the welding machine registration information in the unit, and then reset the fault. |
