During the operation of the OTC DAIHEN Welding Robot, if the system experiences parameter exceptions such as deviation, speed, area, mismatch, and weave amplitude during adaptive control, the teach pendant will usually display a hardware and control-level alarm in the 6335 to 6404 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., 6335), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (6335-6404)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 6335 | Exceeded ZJ Deviation Range | The distance between the detection point and the ZJ reference point exceeds the Z.T deviation range. | Check the detected position, modify (increase) the Z.T deviation range parameter or change the program. |
| 6336 | Adaptive Line Speed Too Fast | The line speed specified by adaptive control exceeds the maximum line speed display value. | Check the data table via WinUser, increase the maximum line speed display value, and then reset the fault. |
| 6337 | Adaptive Line Speed Insufficient | The line speed specified by adaptive control is lower than the minimum line speed display value. | Check the data table via WinUser, decrease the minimum line speed display value, and then reset the fault. |
| 6338 | Area Too Large | The detected area exceeds the maximum allowable value. | Check the area display value (maximum), increase the area display value if necessary, and then reset. |
| 6339 | Area Insufficient | The detected area is lower than the minimum allowable value. | Check the area display value (minimum), decrease the area display value if necessary, and then reset. |
| 6340 | Mismatch Excessive | The detected mismatch exceeds the maximum allowable value. | Check the mismatch display value (maximum), increase the mismatch display value if necessary, and then reset. |
| 6341 | Mismatch Insufficient | The detected mismatch is lower than the minimum allowable value. | Check the mismatch display value (minimum), decrease the mismatch display value if necessary, and then reset. |
| 6342 | Adaptive EN Ratio Too Large | The EN ratio specified by adaptive control exceeds the maximum EN ratio display value. | Check the data table via WinUser, increase the maximum EN ratio display value, and then reset the fault. |
| 6343 | Adaptive EN Ratio Insufficient | The EN ratio specified by adaptive control is lower than the minimum EN ratio display value. | Check the data table via WinUser, decrease the minimum EN ratio display value, and then reset the fault. |
| 6404 | Adaptive Weave Amplitude Too Large | The weave amplitude specified by adaptive control exceeds the maximum weave amplitude display value. | Check the data table via WinUser, increase the maximum weave amplitude display value, and then reset the fault. |

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.
