The following code lists representative error codes of the Sigma-5(with english)
| Error Code | Description | Cause | Solution |
|---|---|---|---|
| A.020 | Overcurrent | Excessive current through the motor (short circuit, abrupt stop, wiring issue) | Check wiring, load conditions, insulation; avoid sudden stops |
| A.030 | Overvoltage | DC bus voltage exceeded allowable limit | Check regenerative resistor, measure input voltage, slow down deceleration |
| A.040 | Undervoltage | DC bus voltage is too low | Check power supply input, ensure stable power |
| A.050 | Overheat | Internal temperature exceeded allowable limit | Inspect cooling fan, improve ventilation, reduce ambient temperature |
| A.070 | Encoder Error | Encoder connection failure or malfunction | Check encoder cable and connector, replace encoder if faulty |
| A.080 | Regenerative Overload | Failure to absorb regenerative energy | Check or upgrade regenerative resistor, inspect for damage |
| A.090 | Parameter Error | Incorrect or corrupted parameters | Reset or reload correct parameters |
| A.100 | Overspeed | Commanded speed exceeds limit | Adjust speed limit settings, verify command input |
| A.120 | Position Error Overflow | Difference between commanded and actual position too large | Adjust servo gains, inspect mechanical system, review parameters |
| A.130 | Overload | Sustained overload operation | Reduce load, adjust duty cycle |
| A.140 | Communication Error | Failed communication with host (MECHATROLINK, Modbus, etc.) | Check communication wiring and parameters |
| A.150 | Insulation Error | Degradation of motor or cable insulation | Perform insulation test, replace motor or cable if needed |
| A.170 | Encoder Battery Low | Absolute encoder battery voltage low | Replace battery (recommended with power on) |
| A.300 | Safety Circuit Error | FLS, RLS, or safety circuit abnormal | Check safety terminals and interlock wiring |
| A.510 | EEPROM Error | Internal data save error | Initialize or replace drive |
| A.520 | RAM Error | RAM data fault | Drive replacement required |
| A.530 | Flash Memory Error | Program memory corruption | Reinstall firmware or replace drive |
| A.710 | Boot Mode Error | Abnormality during drive startup | Restart, attempt firmware recovery |
| A.910 | Safety Parameter Error | FSoE or STO parameter misconfiguration | Review and correct safety parameters |
| A.930 | Zero-Point Setting Error | Failure in home position setup | Retry zero setting, check configuration |
| A.940 | Abnormal Tuning Stop | Tuning aborted due to error | Investigate cause, retry tuning |
| A.950 | File Format Error | Error during parameter save/load | Try a different parameter file or restore defaults |
๐ Notes
- Model Variations: Some error codes may differ slightly depending on the Sigma-5 model (e.g., SGDV, SGDH).
- Immediate Stop Recommended: Most errors trigger system protectionโstop operation and diagnose immediately.
- Monitor Temperature & Voltage: Repetitive overheating or overvoltage can damage internal circuits.
- For Communication Errors: Confirm proper node settings, cable lengths, and master-slave configuration.
- STO/FSoE Safety: The motor will not operate if the STO terminals are not properly configured or closed.
If you need an official Sigma-5 manual (PDF, EN/KO) or model-specific documentation, let me know the exact model number (e.g., SGDV-120D01A) and Iโll provide it accordingly.
