7. Installation & Wiring

1. Power off the entire system and lockout/tagout to prevent electric shock.

2. Mount the amplifier vertically on the cabinet panel with four M5 screws; ensure 100 mm clearance above and below for ventilation.

3. Connect DC bus input (DC+, DC‑) to αi power supply module.

4. Connect 24 VDC control power to the CN1 connector.

5. Connect motor power cables to U/V/W terminals for L‑axis and M‑axis.

6. Connect encoder feedback cables to JF1 (L‑axis) and JF2 (M‑axis).

7. Connect FSSB fiber cable to FSSB IN / OUT for CNC communication.

8. Ground the PE terminal securely to cabinet ground.

9. Verify all connections before restoring power; check LED status and clear alarms.

8. Safety & Warnings

• Warning：High voltage present inside; wait at least 10 minutes after power‑off before opening the cover.

• Warning：Only qualified electrical personnel may perform installation, wiring, or maintenance.

• Caution：Use only FANUC‑specified cables and connectors to avoid damage or fire.

• Caution：Do not connect incompatible motors or encoders; this may cause permanent damage.

• Maintenance：Clean the fan and heat sink every 3–6 months; replace the fan if noisy or faulty.

9. Features & Benefits

• Dual‑axis design saves cabinet space and reduces wiring.

• HRV3 control provides fast response and smooth motion for high‑speed machining.

• Built‑in regeneration reduces energy consumption and external components.

• FSSB fiber communication ensures stable, high‑speed data transmission.

• Absolute encoder backup capacitor maintains position data for 10 minutes after power‑off.
