During the operation of the OTC DAIHEN Welding Robot, if the system experiences abnormalities such as excessive servo deviation, full spot welding count, CPU fan/temperature warning, or automatic backup exception, the teach pendant will usually display a hardware and control-level alarm in the 3010 to 3082 range. If these faults are not investigated promptly, they may cause serious operational safety hazards or burn the core boards.
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., 3010), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (3010-3082)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 3010 | Position at Servo OFF Deviates From Current Position | Due to reasons such as an emergency stop during high-speed operation, the servo could not be disconnected on the normal trajectory. Since the distance exceeds the return limit distance, it cannot return. | When the return limit distance is too narrow, it should be modified in constant mode; to invalidate it, it should be set to 0. |
| 3018 | Spot Welding Count Completed | Exceeded the set number of welding times. | After checking the nozzle, reset the welding counter. There is no special release method. |
| 3021 | Position at Servo OFF Deviates Too Much From Current Position | Due to reasons such as an emergency stop during high-speed regeneration, the robot could not stop normally on the normal trajectory. Since the distance exceeds the error detection distance, it cannot be recovered. | When the error detection limit is too small, it should be modified by constant setting. |
| 3022 | Note: Previous Position Will Not Return at Next Servo ON | At the time of Servo OFF, it is in a state where the return target position cannot be stored; regardless of the return distance, the return action cannot be performed at the next Servo ON. | There is no countermeasure, and no special release is required. |
| 3037 | External Operation of Servo Welding Gun Not Allowed While Running Program | The external operation of the servo welding gun was executed while running a program. | External operation should be executed when the program stops or the servo welding gun is disconnected. No reset operation is required. |
| 3057 | Cannot Start While Reading/Writing Text | This error occurs if start is input while performing operations on the text read/write screen. | The start command should be input after the text read/write operation is completed. No reset operation is required. |
| 3077 | CPU Fan Warning | An exception appears when the fan speed on the CPU board decreases. | 1. Check if the fan is running, or clean the fan; 2. Replace the CPU fan; 3. Replace the CPU board. Fault reset. |
| 3079 | CPU Board Temperature Warning | Detected that the temperature on the CPU board exceeds the alarm temperature. | 1. Check if the fan is running, or clean the fan; 2. Replace the CPU fan; 3. Replace the CPU board. Fault reset. |
| 3081 | Auto Backup Cannot Connect to FTP Server for Auto Backup | Not connected to the FTP server of the backup destination for auto backup, or neither the initial folder nor the name exists in the home directory of the FTP server. | Confirm the host name, user account, password, and initial folder of the FTP client. No reset operation is required. |
| 3082 | Exception Occurred During Auto Backup Creation | Cannot automatically create a backup. It may be that the storage media is not ready, write-protected, or has insufficient storage capacity. | Confirm the status of the storage media. There is no special release method. |

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.
