During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as angle detection, arc sensing, or wire feeding issues, the teach pendant will usually display a hardware and control-level alarm in the 6308 to 6334 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., 6308), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (6308-6334)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 6308 | Angle 1 Too Small | The detected angle 1 is smaller than the minimum allowable value. | Check the size of angle 1, modify the allowable value if necessary, and then execute an exception reset. |
| 6309 | Angle 2 Too Large | The detected angle 2 exceeds the maximum allowable value. | Check the size of angle 2, modify the allowable value if necessary, and then execute an exception reset. |
| 6310 | Angle 2 Too Small | The detected angle 2 is smaller than the minimum allowable value. | Check the size of angle 2, modify the allowable value if necessary, and then execute an exception reset. |
| 6311 | Groove Not Detected | Failed to detect the groove position. | Check the setting parameters in the GFF file, and then execute an exception reset. |
| 6312 | Unstable Direction | This error occurs when the measured data is unstable. | Check the target surface conditions and/or measurement angle, and then execute an exception reset. |
| 6330 | 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 in the teaching parameter, or adjust the sensor. |
| 6331 | Calculation Unstable During Arc Sensing | The stability of arc welding decreased significantly. | Correct the welding conditions to make them stable, and then execute an exception reset. |
| 6332 | Cannot Detect Welding Position | Deviation detection cannot be calculated during arc sensing. | Readjust the sensing parameters, and then execute an exception reset. |
| 6333 | Wire Feed Unstable | The wire feed status becomes unstable and the deviation exceeds the specified value. | Check the wire feed device, and then execute an exception reset. |
| 6334 | ST Parameter Error | The teaching parameters of the ST command exceed the setting range. | Confirm whether each parameter is within the setting range, 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.
