During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as search timeout, sensor installation parameter error, or starting point not detected, the teach pendant will usually display a hardware and control-level alarm in the 5224 to 5233 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., 5224), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (5224-5233)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 5224 | Search Timeout | This error occurs when the search time is too long. | Reduce the search time to less than 2 seconds or modify the sampling frequency, and then execute an exception reset. |
| 5225 | Sensor Installation Parameter Error | This error occurs when the sensor installation parameter is not set. | Specify the sensor installation direction, calibrate the sensor, and then execute an exception reset. |
| 5226 | Laser Sensor Not Ready | The laser sensor power is not turned on or communication is not connected. | Check the laser sensor power and communication cable, and then execute an exception reset. |
| 5227 | Sensor Internal Fault | The laser sensor internal self-test found an exception. | Restart the sensor power; if ineffective, contact maintenance to replace the sensor. |
| 5228 | Measurement Out of Range | The distance measured by the sensor exceeds the valid measurement range. | Adjust the robot posture to ensure the workpiece is within the effective range of the sensor, and execute an exception reset. |
| 5229 | Reflectivity Exception | The reflection from the workpiece surface is too strong or too weak, causing the sensor to fail to receive a valid signal. | Adjust the laser irradiation angle or clean the workpiece surface, and then execute an exception reset. |
| 5230 | Sensor Communication Timeout | The data exchange between the control device and the sensor timed out. | Check the communication cable shielding and grounding, eliminate interference, and then execute an exception reset. |
| 5231 | Sensor Temperature Too High | The internal temperature of the sensor exceeds the operating upper limit. | Check the heat dissipation environment of the sensor and wait for it to cool before restarting. |
| 5232 | Sensor Trigger Signal Not Received | When executing a measurement command, the sensor did not feed back a successful trigger signal. | Check the I/O signal configuration and sensor trigger circuit, and execute an exception reset. |
| 5233 | Sensor Calibration Data Lost | The calibration data inside the sensor was cleared or damaged. | Use a calibration tool to recalibrate the laser sensor, and then execute 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.
