During the operation of the OTC DAIHEN Welding Robot, if the system experiences abnormalities such as command pressure out of range, welding machine preparation incomplete, multi-drive axis basic position deviation, or storage media read/write exception, the teach pendant will usually display a hardware and control-level alarm in the 2048 to 2083 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., 2048), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (2048-2083)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 2048 | Command Pressure Out of Range | This error occurs when the specified pressure of the servo welding gun is too large or too small. | Use a pressure suitable for the servo welding gun used, and then reset the exception. |
| 2049 | Welding Machine Preparation Incomplete or Welding Allow Signal Not ON | The power of the welding machine is not turned on, or the welding machine has an exception, or the welding allow signal is not input. | Check the peripheral devices and the welding machine, and then reset the exception. |
| 2050 | Robot Not Maintaining Basic Position Among Multi-Drive Axes | This error occurs when the robot does not maintain the basic position among the multi-drive axes. | Use manual operation (without using multi-drive control) to return the robot to the basic position. Check the basic position or error detection level. Exception reset. |
| 2055 | Pressure Has Reached Specified Value for Manual Operation | The servo welding gun pressure has reached the specified value for manual operation, but the servo welding gun axis does not move (the pressure value is too low). | Modify the pressure data, and then reset the exception. |
| 2059 | Interpolation Action and Acceleration/Deceleration Control May Be Abnormal | The orthogonal coordinate setting at the time of tool registration is different from the current one, resulting in inconsistent setting of the orthogonal coordinate system. | Reset the tool constant with the current orthogonal coordinate system and change the setting. |
| 2060 | Axis 4 Out of Operating Range | This error occurs when the 4th axis exceeds its operating range. Occasionally, it may also be exceeded due to interference from other axes. | In [Constant]-[Mechanical Constant], use the axis operation key to move back to the operating range (be careful of collision). No reset operation is required. |
| 2062 | Welding Conditions Do Not Exist | When setting welding conditions by group, the condition number is out of range, or the transfer fails when the power is turned on. | Confirm the required condition number and try again. |
| 2063 | Welding Condition Group Number Not Set | The welding conditions were not recorded using the group function when executing the spot welding function. | Before executing the spot welding function, use the group function to record the welding conditions. |
| 2082 | Storage Media Not Ready | During file operation, the specified device was not detected. | Confirm whether the device such as a memory card specified by the file operation option is correctly attached. Press any key to release the error. |
| 2083 | Storage Media Write Protected | Write protection is displayed when copying to the memory card. | Prepare a writable storage medium and copy again from the beginning. Press any key to release the error. |

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.
