During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as end point not detected, laser control failure, unstable arc sensing, or sensor not connected, the teach pendant will usually display a hardware and control-level alarm in the 5244 to 5253 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., 5244), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (5244-5253)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 5244 | End Point Not Detected | The end point of the workpiece was not detected. | Modify (increase) the ZN search range or program to correct the error, and then perform an exception reset. |
| 5245 | Exceeded Deviation Range | The distance between the detected end point and the taught point before ZE exceeds the deviation range. | Check the detected point, modify (increase) the deviation range or program to correct the error, and then perform an exception reset. |
| 5246 | Laser ON Failed | The laser is not turned on. | Use Z0N or manual operation to set the laser to ON, and then perform an exception reset. |
| 5247 | Laser Not Ready | ZF/ZT/ZJ is executed within 3 seconds after executing Z0N. | Wait for 3 seconds or more after Z0N execution before executing ZF/ZT/ZJ, and then perform an exception reset. |
| 5248 | Teaching Error in ZN Command | There is no movement command before/after the ZN command, or not enough movement commands are taught between ZN and ZE. | Improve teaching, and then perform an exception reset. |
| 5249 | Exceeded ZT Posture Deviation Range | The robot moved outside the posture deviation range. | Check the target posture, modify (increase) the ZT parameter or program to correct the error, and then perform an exception reset. |
| 5250 | Sensor Not Connected | The control device cannot communicate with the sensor. | Turn on the power of the sensor; check the connection between the sensor and the control device, and then perform an exception reset. |
| 5251 | Arc Sensor Compensation Amount Exceeds Specified Value | The sensor compensation amount exceeds the specified value in the teaching parameters. | Check the welding torch position; increase the CHASINGRANGE value in the parameters or adjust the sensor, and then perform an exception reset. |
| 5252 | Calculation Unstable During Arc Sensing | The stability of arc welding decreased significantly. | Correct the welding conditions to make them stable, and then perform an exception reset. |
| 5253 | Cannot Detect Welding Position | Deviation detection cannot be calculated during arc sensing. | Readjust the sensing parameters, and then perform an exception reset. |

When the robot frequently displays the above hardware-level alarms, and routine reset attempts are ineffective, do not forcefully pull the robot arm or repeatedly force restarts, so as not to cause secondary irreversible damage.
