Sub Code: Signifies the axis in
which the alarm occurred
Causes and remedies
| Cause | Remedy |
|---|---|
| Cable (abnormal) | 1. Reset the alarm. 2. If the alarm recurs, check that the following cables and connectors are connected and fully inserted. • SDCA01 board-CN501, CN531, CN532, CN533, CN540, CN541 • Inverter board-CN571, CN573-579 • CPS01 unit-CN157 • SDB (external axis servo unit)-CN591, 594 • Continuity of the motor power cable |
| Cable (abnormal) | 1. Check that the U, V, and W phase wires of the motor power cable are not broken. 2. If a wire is broken, replace the motor power cable. |
| Cable (abnormal) | 1. Check that the motor brake cable has no broken wires. 2. If a wire is broken, replace the motor brake cable. |
| SDCA01 board (abnormal) | 1. Reset the alarm. 2. If the alarm recurs, replace the SDCA01 board. As a precaution, save CMOS.BIN before replacing the board. |
| Amplifier (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the amplifier. |
| Motor (abnormal) | 1. Turn the power off and back on. 2. If the alarm recurs, replace the motor. |
| 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.). |
