Product Overview

• Brand: FANUC Corporation
• Model: A06B-6097-H204
• Series: Alpha i Series (High-Power Servo Amplifier Line)
• Type: 3-Axis Integrated Servo Amplifier Module
• Industry: CNC machining (milling machines, lathes, machining centers), industrial robotics (FANUC robots, collaborative robots), automated assembly lines, and precision manufacturing (aerospace, automotive, electronics).
• Function: Acts as a central drive unit to control up to 3 independent servo motors. It receives motion commands from a FANUC CNC controller (e.g., FANUC 0i, 30i/31i/32i-B Series) or robot controller, converts these commands into precise electrical power signals, and drives servo motors to achieve high-accuracy position, speed, and torque control. The module integrates power conversion, signal processing, and safety functions to ensure smooth, reliable motion for critical manufacturing processes.

Key Features

1. 3-Axis Integrated Design
   • Combines 3 independent servo drive channels in a single compact unit, reducing the required installation space in control cabinets compared to single-axis amplifiers. This integration simplifies wiring (shared power input and communication bus) and lowers system complexity for multi-axis equipment (e.g., 3-axis CNC milling machines).
   • Each axis supports independent parameter configuration (e.g., motor type, control mode, gain settings) via FANUC’s Servo Guide software or CNC controller HMI.
2. High-Precision Motion Control
   • Equipped with FANUC’s advanced High-Response Digital Servo (HDS) technology, which delivers a control loop update rate of up to 250 µs (4 kHz). This enables ultra-fast response to command changes, minimizing following error and ensuring precise trajectory control (critical for high-speed machining of complex parts).
   • Compatible with FANUC’s high-resolution feedback devices:
     • Absolute Encoders: Up to 21-bit resolution (2,097,152 pulses/revolution) for servo motors, enabling sub-micron positioning accuracy.
     • Linear Scales: Supports external linear encoders (e.g., FANUC FSL Series) for direct position feedback, eliminating backlash and pitch error in linear axes.
3. Comprehensive Safety Functions
   • Integrates FANUC’s Safety Integrated features to meet international machine safety standards (EN ISO 13849-1, IEC 61508):
     • Safe Torque Off (STO): Disables motor torque without cutting main power, preventing unexpected motion during maintenance or emergencies.
     • Safe Stop 1 (SS1): Decelerates the motor to a stop before activating STO, reducing mechanical stress on equipment.
     • Overcurrent/Overvoltage Protection: Monitors input/output currents and voltages, triggering shutdowns to protect the amplifier and connected motors from damage.
4. Energy Efficiency & Durability
   • Incorporates an Active Front End (AFE) (model-dependent) to reduce harmonic distortion (THD < 5%) and improve power factor (> 0.95) at the input side, complying with IEEE 519 power quality standards. The AFE also enables regenerative braking, feeding back excess energy from decelerating motors to the AC grid, reducing energy consumption.
   • Rugged industrial design withstands harsh manufacturing environments:
     • Resistant to vibration (IEC 60068-2-6: 10–500 Hz, 5g) and shock (IEC 60068-2-27: 30g peak).
     • Wide operating temperature range (-10°C to +55°C) and dust/water resistance (IP20 when mounted in a control cabinet).

Applications

• CNC Machining Centers:
  • Controls the X, Y, and Z axes of 3-axis CNC milling machines or machining centers, enabling high-speed cutting of metal or composite parts (e.g., automotive engine blocks, aerospace components). The high-response servo system ensures tight tolerance control (±0.001 mm) for precision machining.
• Industrial Robotics:
  • Drives the joint motors of FANUC articulated robots (e.g., LR Mate 200iD, CRX Series collaborative robots), providing smooth motion for pick-and-place, assembly, or welding tasks. The 3-axis design can also be paired with additional amplifiers for 6-axis robot control.

Installation and Maintenance Notes

1. Setup Requirements:
   • Mount in a control cabinet with minimum 100 mm clearance on all sides to ensure adequate airflow for cooling. Avoid installing near heat sources (e.g., transformers, power supplies) to prevent overheating.
   • Configure via FANUC Servo Guide software to match the connected servo motors: load motor parameters (from FANUC’s motor database), set feedback type (absolute/ incremental), and tune servo gains (position loop gain, speed loop gain) for optimal performance.
2. Wiring Guidelines:
   • Use shielded, twisted-pair cables for FSSB communication to minimize electromagnetic interference (EMI) from nearby power cables.
   • For power input, use cables sized according to the amplifier’s rated current (e.g., 16 mm² copper cables for 20 A per axis) and install a dedicated circuit breaker (3-phase, 50 A) for overcurrent protection.
   • Connect the STO safety signal to the machine’s emergency stop circuit to ensure compliance with safety standards.
3. Safety & Troubleshooting:
   • Follow lockout-tagout (LOTO) procedures when wiring or servicing the amplifier—disconnect main power and activate STO to prevent unexpected motor motion.
   • Use the amplifier’s front-panel LED indicators to diagnose status:
     • Green (POWER): Amplifier is powered on.
     • Green (READY): All axes are ready for operation.
     • Red (ALM): Fault detected (e.g., overcurrent, overvoltage, motor overload).
   • For faults, check the FANUC CNC/robot controller’s alarm history (e.g., Alarm 410: Servo Amplifier Overcurrent) and use Servo Guide to analyze waveform data (current, speed, position) for root cause identification. Common issues include loose wiring, motor winding shorts, or incorrect parameter settings.

Critical Notes

1. Model Variability: The A06B-6097-H204 may have sub-variants (indicated by suffixes) for different voltage ranges (200V vs. 400V) or safety features (STO vs. SS1). Confirm the exact variant with FANUC to match your equipment’s power supply and safety requirements.
2. Motor Compatibility: Ensure the amplifier’s current rating (20 A continuous) matches or exceeds the connected servo motors’ rated current. Overloading the amplifier can cause overheating and permanent damage.
3. Genuine Parts Only: Use genuine FANUC A06B-6097-H204 amplifiers for safety-critical applications. Aftermarket alternatives may not meet FANUC’s precision standards or safety certifications, risking motion errors, equipment damage, or safety hazards.
