During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as adaptive running speed exception, automatic calibration failure, or reference point positioning error, the teach pendant will usually display a hardware and control-level alarm in the 5298 to 5307 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., 5298), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (5298-5307)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 5298 | Adaptive Running Speed Too Fast | The running speed specified by adaptive control exceeds the maximum speed display value. | Check the data table, increase the maximum speed display value for adaptive control, and then reset the fault. |
| 5299 | Adaptive Running Speed Insufficient | The running speed specified by adaptive control is lower than the minimum speed display value. | Check the data table, decrease the minimum speed display value for adaptive control, and then reset the fault. |
| 5300 | Cannot Execute Automatic Calibration Function | There is an error in the recording method of functions related to automatic calibration. | The automatic calibration function should be recorded after the movement command, or the mechanism should be correctly selected for CheckGo. |
| 5301 | Other Devices Are Running Programs | CALIBROB (FN702) cannot be executed while executing a program for another device. | After stopping all devices, execute CALIBROB (FN702) again, and perform an exception reset. |
| 5302 | Maximum Compensation Value Error | The compensation amount for joint deviation or tool parameters exceeds the maximum value set by the constant. | Use the welding torch gauge or point mark to correct the clearance of the robot and then acquire the measurement point again, and perform an exception reset. |
| 5303 | Maximum Search Distance Error | This error occurs when the robot moves outside the search range. | Modify (increase) the search range or program, correct the error, no reset operation is required. |
| 5304 | Reference Point for Automatic Calibration Not Acquired | This error occurs when the reference point is not acquired. | Acquire the reference point, no reset operation is required. |
| 5305 | Reference Point Positioning Error | This error occurs when points “A” and “B” have different positionings. | Make points “A” and “B” have the same positioning, no reset operation is required. |
| 5306 | Reference Point Positioning Error (During Search in Z Direction) | The positioning of the reference point during search in the Z direction is different from A1/B1 or A2/B2. | Make points A1 and B1 have the same posture as point A in the Z direction, or A2 and B2 have the same posture as point B in the Z direction, no reset is required. |
| 5307 | Automatic Calibration Sensor Not Registered | This error occurs when the automatic calibration sensor required for the search operation is not set. | Use the constant setting to register the automatic calibration sensor, 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.
