During the operation of the OTC DAIHEN Welding Robot, if the system experiences a corresponding fault condition, the teach pendant will usually display a hardware and control-level alarm in the 0027-0039 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, to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (0027-0039)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 0027 | Inconsistent Position Detection Exception. | This exception is issued when there is a difference between the position information measured by the main board and the position information measured by the servo board (UM221). | The main board or servo board (UM221) may be malfunctioning. When this exception occurs, it may be in a state where it cannot move. Please contact our maintenance service department. After eliminating the cause of the exception, reset the exception. |
| 0028 | Multiple Drive Control Exception. | This exception is issued when an abnormal state occurs in which multiple drive control (coordination of 2 robots) cannot be executed. | Please contact the repair service department. After eliminating the cause of the exception, reset the exception. |
| 0029 | Safety Plug-in Board Exception Occurred. | An exception was input to the safety plug-in board. | Please confirm the exceptions around the safety plug-in board. After eliminating the cause of the exception, reset the exception. |
| 0030 | Safety Plug-in Board Communication Exception Occurred. | Communication with the safety plug-in board is impossible due to noise or other reasons. | Turn on the power again. If it still does not recover, there may be a malfunction; please contact our maintenance service department. Turn on the power again. |
| 0031 | Unable to Detect Safety Plug-in Board Exception. | When the power is turned on, the system does not detect the safety plug-in board (UM216). The safety plug-in board is not connected or the connector has fallen off. | Please properly reconnect the safety plug-in board (UM216). |
| 0032 | Robot Body Power Cable Disconnected. | The drive power (power cable) of the robot body may be disconnected. For safety reasons, if the power is turned on while the power cable is disconnected, an error will occur after the robot servo is turned on. | Confirm whether the power cable behind the robot body is disconnected. If it still does not recover, the drive unit may be malfunctioning. Please contact our maintenance service department. |
| 0033 | Exception Detected by Watchdog Timer. | The safety plug-in board is not working properly due to noise or other reasons. | Please turn on the power again. If it still does not recover, the safety plug-in board may be malfunctioning; please contact our maintenance service department. Turn on the power again. |
| 0037 | Internal Electromagnetic Switch Action Exception. | The main board did not receive the signal that the internal electromagnetic switch has been activated. | Restart the Servo ON operation. If the fault persists, please contact our maintenance service department. |
| 0038 | Inconsistent Servo ON Condition Exception. | The servo startup operation was performed within 10 seconds after turning on the control power. | The Servo ON operation should be performed more than 10 seconds after turning on the control power. After eliminating the cause of the exception, reset the exception. |
| 0039 | Servo ON Internal State Exception. | A state inconsistency occurred in the drive unit right before turning to the operation preparation state. | Restart the Servo ON operation. If the fault persists, please contact our maintenance service department. |
