During the operation of the OTC DAIHEN Welding Robot, if the system experiences a position command interrupt, a calculation error in the motion control section, or a braking delay, the teach pendant will usually display a hardware and control-level alarm in the 9022 to 9102 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., 9030), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (9022-9102)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 9022 | Waiting for Precise Position Arrival Error | The robot did not accurately reach the set target position. | Please contact the maintenance service department, back up the files to an external CF memory, and perform an error reset. |
| 9023 | Position Command Interrupt Error | The position command at the motion control level was abnormally interrupted. | Please contact the maintenance service department, back up the files to an external CF memory, and perform an error reset. |
| 9024 | Mechanism Resource Acquisition Error | Failed to successfully acquire underlying mechanism resources in the motion control section. | Please contact the maintenance service department, back up the files to an external CF memory, and perform an error reset. |
| 9025 | Safety Deceleration Error | The robot’s operating speed did not decrease to the safety level according to the command. | Please contact the maintenance service department, back up the files to an external CF memory, and perform an error reset. |
| 9026 | Stop Release Error | The stop command in the motion control section was not successfully released. | Please contact the maintenance service department, back up the files to an external CF memory, and perform an error reset. |
| 9028 | Motion Calculation Error | A system calculation logic error was detected in the motion control section. | Please contact the maintenance service department, back up the files to an external CF memory, and perform an error reset. |
| 9030 | Braking Delay Exception During Interference Check | The detected mechanical interference or obstruction persists beyond the specified time, causing the brake axis to fail to lock successfully. | Press the “Motor ON” key on the teach pendant to start the servo motor for an error reset, or turn on the drive preparation again. |
| 9100 | Interpolation Calculation Stopped | The trajectory interpolation calculation was abnormally stopped in the motion control section. | Please contact the maintenance service department, back up the files to an external CF memory, and turn on the control power again. |
| 9101 | Operating Time Exceeded | The robot failed to continuously execute work commands within the timeout threshold. | Please contact the maintenance service department, back up the files to an external CF memory, and turn on the control power again. |
| 9102 | Cannot Continue Regeneration | The underlying system cannot process I/O communication signals normally. | Please contact the maintenance service department, back up the files to an external CF memory, and turn on the control power again. |

When the robot frequently displays hardware-level alarms involving motion calculation exceptions or interpolation stops, 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 to the reducer or servo drive.
