Causes and remedies
| Cause | Remedy |
|---|---|
| SDCA01 board (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the SDCA01 board. As a precaution, save CMOS.BIN before replacing the board. • Check the position after the alarm occurs |
| Cable (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, check that the following cables and connectors are connected and fully inserted. [Robot axes] • Cable between encoders • SDCA01 board-CN508 [External axis] • Cable between encoders • SDCA01 board-CN534, CN535, CN536 |
| External influence (interference) | Check the following settings. • Check the grounding of the robot body. • Install a ferrite core on the motor power cable. |
| Other | If the alarm occurs again after implementing the countermeasures, contact our service department and describe the circumstances when CMOS.BIN was saved (operating procedure, etc.). |
