During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as measurement point error, speed/current/voltage monitoring exception, adaptive weave amplitude, or ZF posture deviation, the teach pendant will usually display a hardware and control-level alarm in the 5334 to 5410 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., 5334), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (5334-5410)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 5334 | Measurement Point Error | The measurement point was not acquired starting from point 1Q. | Acquire the measurement point starting from point 1Q, and then perform an exception reset. |
| 5335 | Measurement Point Error | The measurement point was not acquired starting from point 1A. | Acquire the measurement point starting from point 1A, and then perform an exception reset. |
| 5400 | Speed Monitoring Range Setting Exception | An exception occurs when the minimum value of speed monitoring exceeds the maximum value set in the adaptive control state. | Check the minimum and maximum values of the speed monitoring value, and then reset the fault. |
| 5401 | Current Monitoring Range Setting Exception | An exception occurs when the minimum value of current monitoring exceeds the maximum value set in the adaptive control state. | Check the minimum and maximum values of the current monitoring value, and then reset the fault. |
| 5402 | Voltage Monitoring Range Setting Exception | An exception occurs when the minimum value of voltage monitoring exceeds the maximum value set in the adaptive control state. | Check the minimum and maximum values of the voltage monitoring value, and then reset the fault. |
| 5403 | Adaptive State Setting Exception | An illegal setting of the adaptive state was changed in the tracking section, making it impossible to switch the validity and invalidity of the adaptive control in the tracking section. | Determine the specified LSR file number and confirm the setting content, and then reset the fault. |
| 5404 | Adaptive Weave Amplitude Too Large | The weave amplitude specified by adaptive control exceeds the maximum weave amplitude display value of the adaptive control. | Use WinUser to check the data table, increase the maximum weave amplitude display value for adaptive control, and then reset. |
| 5406 | Exceeded ZF Posture Deviation Range | The difference between the target posture calculated by the ZF command and the taught posture exceeds the posture deviation range. | Check the target posture, modify (increase) the ZF parameter or change the program, and then reset the fault. |
| 5408 | Maximum Distance in ZN Command Too Long | The target position calculated by the ZN command exceeds the movable area. | Shorten the maximum distance in the ZN command, and then reset the fault. |
| 5410 | Stability Waiting Time Too Long | The stability waiting time has been exceeded. | Modify (increase) the Z.T stability waiting time to correct the error, 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.
