During the operation of the OTC DAIHEN Welding Robot, if the system experiences abnormalities such as glass processing movement amount over limit, conveyor belt synchronization exception, MAPPING/ALIGNMENT function execution conflict, or sensor fault, the teach pendant will usually display a hardware and control-level alarm in the 2670 to 2679 range. If these faults are not investigated promptly, they may cause serious operational safety hazards or damage peripheral devices.
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., 2670), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (2670-2679)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 2670 | Y Bending Movement Amount Greater Than Error Limit | In the glass processing operation, the calculated value of the Y-axis bending movement amount exceeds the error limit set by the system. | 1. Verify the parameter configuration of the “XY Bending Table”; 2. Modify the Y bending movement amount value to make it lower than the error limit; 3. Exception reset. |
| 2671 | Conveyor Belt Synchronization Not Turned On (Not ON) | The current program/function command requires the conveyor belt synchronization function to be ON, but the function is not actually enabled. | 1. Enter the parameter interface and set the “Conveyor Belt Synchronization” function to ON (enabled); 2. Exception reset. |
| 2672 | MAPPING Function Usage Incorrect | During the execution of the MAPPING function, the MAPPING execution command is repeatedly issued, resulting in a function conflict. | 1. Check the command call logic and delete repeated MAPPING execution commands; 2. After correcting and saving the program, exception reset. |
| 2673 | ALIGNMENT Function Usage Incorrect | During the execution of the ALIGNMENT function, the ALIGNMENT execution command is repeatedly issued, resulting in a conflict. | 1. Check the command call logic and delete repeated ALIGNMENT execution commands; 2. After correcting and saving the program, exception reset. |
| 2674 | ALIGNMENT Sensor Not Opened/No Input | During the ALIGNMENT calibration search process, the system did not detect the input signal of the alignment sensor. | 1. Confirm that the workpiece passes through the detection area normally and adjust the sensitivity; 2. Check the wiring for short/open circuits; 3. Exception reset. |
| 2675 | Bending Movement Amount Greater Than Error Limit | In the glass processing operation, the calculated value of the overall bending movement amount exceeds the error limit set by the system. | 1. Verify the parameter configuration of the “Bending Table”; 2. Modify the bending movement amount value to make it lower than the error limit; 3. Exception reset. |
| 2676 | SJ Type Manipulator Executed Unsupported Function | A function command not supported by the SJ type manipulator hardware/firmware was called in the current program. | 1. Check the function manual to confirm unsupported functions; 2. Delete or replace with supported function commands. The alarm is automatically eliminated. |
| 2677 | Welding Machine Main Error | The welding machine control board detected a core welding error (such as overcurrent, overvoltage, phase loss) and fed back the fault to the system. | 1. Check the code on the welding machine control panel to locate the cause; 2. Eliminate the core welding error; 3. Exception reset. |
| 2678 | Welding Command Not Executed | The welding machine control board aborted the execution of the welding command sequence due to a fault, and did not respond to the command issued by the robot. | 1. Troubleshoot the cause of the welding machine fault (communication exception, parameter error, etc.); 2. Repair the fault; 3. Exception reset. |
| 2679 | Torsion Movement Amount Greater Than Error Limit | In the glass processing operation, the calculated value of the torsion movement amount exceeds the error limit set by the system. | 1. Verify the parameter configuration of the “Torsion Table”; 2. Modify the torsion movement amount value to make it lower than the error limit; 3. 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.
