• Humidity: 10%–90% RH, non‑condensing

• Cooling: Forced air cooling (drive internal fan)

5. Common Alarm Codes (Servo Drive)

• SV‑01: Overcurrent → Check motor wiring, insulation, power module

• SV‑02: Overvoltage → Check input voltage, regeneration circuit

• SV‑03: Undervoltage → Check power supply, fuses, wiring

• SV‑04: Overheat → Check cooling fan, heatsink, ambient temperature

• SV‑05: Speed deviation → Check encoder, cable, motor load

• SV‑06: Encoder error → Check encoder connection, cable, encoder unit

6. Maintenance & Handling

• ESD Protection: Always use anti‑static wristband when handling PCB

• Visual Inspection: Check for burnt components, swollen capacitors, loose connectors

• Cleaning: Remove dust from PCB surface and connectors every 3–6 months

• Connector Check: Ensure pins are secure and free of oxidation

• Voltage Verification: Confirm +5 V and ±15 V supply voltages before power‑up

7. Safety Notes

• High Voltage: Power off drive and discharge capacitors (wait ≥10 minutes) before service

• Qualified Personnel: Only trained technicians should perform installation/maintenance

• Genuine Parts: Use FANUC original replacement parts to ensure reliability

8. Compatibility

• Replaces: A16B-1100-0280 series (/06A, /08A) and other compatible revisions

• Pin‑to‑pin: Mechanically and electrically interchangeable with compatible boards
