Key Features

• High Precision Control: Dedicated RISC processor for fast response; smooth motion with minimal torque ripple.

• Fiber-Optic Communication: FSSB bus ensures high-speed, noise-immune data transmission up to 50 m, reducing EMI interference.

• Modular Design: Compact, stackable form for easy integration into electrical cabinets; shared parts for simplified maintenance.

• Robust Protection: Comprehensive fault detection with LED alarms; safeguards against motor/amplifier damage.

• Global Compliance: CE, UL, and RoHS certifications for worldwide industrial deployment.

Application Scope

• CNC Machine Tools: Lathes, mills, machining centers, grinders (αi-B series compatible).

• Robotics: FANUC R-30iB series robot controllers (6-axis servo drive).

• Automation Equipment: High-speed positioning systems, multi-axis synchronisation platforms.

• Retrofit Projects: Replacement for older FANUC servo systems (e.g., A06B-6050/6060 series).

Installation Instructions

1. Pre-Installation: Power off the CNC/robot controller; disconnect all cables. Mount the amplifier vertically in a ventilated cabinet (allow 100 mm clearance top/bottom for cooling).

2. Wiring: Connect AC power to the L1/L2 terminals; link motor power cables to U/V/W; connect encoder feedback to the FSSB fiber port. Use shielded cables for all signal lines.

3. Grounding: Ensure reliable PE (protective earth) connection to reduce EMI and electric shock risk.

4. Configuration: Power on the system; set servo parameters via the CNC/robot teach pendant (e.g., motor type, gear ratio, homing mode).

5. Testing: Perform a trial run with no load; verify smooth movement and correct encoder feedback.

Wiring Requirements

• Power Cables: Use 2.5–4 mm² copper wires for AC power; 4–6 mm² for motor power (per model current rating).

• Signal Cables: FANUC-certified shielded twisted-pair cables for encoder signals; separate high-power and signal cables by ≥30 cm to avoid crosstalk.

• Fiber Optics: Use FSSB single-mode fiber connectors; avoid sharp bends (radius >50 mm) to prevent signal loss.

• Terminals: Tighten all screws to 1.2–1.5 N·m; ensure no loose wires or cold joints.

Working Environment

• Ambient Temperature: 0°C to +55°C (operating); –20°C to +70°C (storage).

• Humidity: ≤85% RH (non-condensing).

• Vibration: ≤0.5 g (10–100 Hz); avoid direct impact.

• Atmosphere: No corrosive gases, oil mist, or conductive dust; keep cabinet dry and ventilated.

Maintenance Instructions

• Daily Check: Verify LED status (normal: POWER green, ALARM off); check for abnormal noise or overheating.

• Monthly Maintenance: Power off and clean dust from cooling fans/vents with a dry brush; check cable connections for tightness.

• Quarterly Inspection: Test FSSB fiber continuity; verify encoder signal quality; check for terminal oxidation.

• Annual Service: Replace aging cooling fans; back up servo parameters; perform full-load operation test.

Safety Precautions

• Qualified Personnel: Only certified electrical technicians may install, wire, or maintain the amplifier.

• Power Safety: Never connect/disconnect cables while powered on; wait 10 minutes after power-off for capacitor discharge.

• Fault Handling: If an alarm triggers (e.g., overcurrent), power off immediately; inspect motor, wiring, and load before restarting.

• Modification: Do not alter internal circuits or use non-FANUC replacement parts; voids warranty and risks safety hazards.
