| Feature | A06B-6117 Series | A06B-6127-H104 |
Communication | FSSB | FSSB (Improved speed) |
Axis Support | 1-axis | 1-axis (but with newer firmware) |
Cooling | Forced air | Enhanced airflow + fan diagnostics |
Integration | Basic | Optimized for newer αi servo motors |
The 6127-H104 offers updated firmware, better efficiency, and smoother integration with modern CNC controllers compared to older 6117 models.
Like other αi amplifiers, this model reports real-time faults through LEDs and CNC display. It aligns with FANUC’s standard fanuc drive alarm list, supporting alarms such as:
| Alarm Code | Description |
AL-01 | Output overcurrent |
AL-02 | Overvoltage in DC bus |
AL-04 | Fan fault or insufficient cooling |
AL-06 | Regenerative discharge circuit failure |
AL-12 | Communication error via FSSB |
Understanding these codes allows for quick diagnostics and minimized downtime, critical in high-volume production environments.
