Key Specifications and Features

  • Model: A06B-6117-H203
  • Series: αi SV 4/20 (Dual-Axis Configuration with Asymmetric Power Ratings)
  • Rated Output Current:
    • Axis 1: 4Arms (continuous), 8Arms (peak, 100ms)
    • Axis 2: 20Arms (continuous), 40Arms (peak, 100ms)
  • Control Method: Full-digital sine-wave PWM with IGBT bridge and HRV3+ control technology, achieving a current loop bandwidth of 1.8kHz for rapid torque response.
  • Input Power: Three-phase AC200V (±10%), 50/60Hz, with active power factor correction (PFC) to reduce harmonic distortion and energy consumption.
  • Compatible CNC Systems: Fully compatible with FANUC 0i-F Plus, 30i/31i/32i-MODEL B Plus, and Power Motion i-MODEL A controllers, supporting advanced functions like AI Nano Contour Control and AI Thermal Displacement Compensation.
  • HRV3+ Control: Enhances position/speed accuracy by suppressing mechanical resonance and vibration, enabling ±0.002mm positioning repeatability in precision machining.
  • Integrated Safety Functions:
    • Overcurrent, overvoltage, overheat, and short-circuit protection.
    • Real-time monitoring of motor temperature, insulation resistance, and encoder health.
    • Compliance with ISO 13849-1 (PL d) and IEC 61508 (SIL 2) safety standards.
  • Thermal Design:
    • Forced-air cooling with integrated temperature sensors and automatic derating at high ambient temperatures.
    • High-efficiency heat sinks and vibration-resistant PCBs for operation in 0°C to +55°C environments.
  • Modular Architecture:
    • Supports daisy-chaining of up to four αi SV 4/20 amplifiers for eight-axis synchronization.
    • Hot-swappable design with LED status indicators for easy maintenance.

Performance Advantages

  • Mixed-Power Axis Control:
    • Ideal for applications requiring one low-power axis (e.g., rotary table) and one high-power axis (e.g., linear feed drive) in a single module.
    • 20-bit absolute encoder feedback (1,048,576 pulses/rev) enables sub-micron positioning accuracy.
  • Energy Efficiency:
    • 97% power conversion efficiency reduces energy waste and heat generation.

    • Active regeneration circuitry recovers braking energy, lowering operational costs.
  • Industrial Robustness:
    • IP67-rated connectors and conformal-coated PCBs resist dust, moisture, and vibration.
    • Shock resistance of 30G (11ms) and vibration resistance of 5–500Hz (1.5G) ensure reliability in harsh environments.
  • Smart Diagnostics:
    • Built-in AI Servo Tuning optimizes PID gains automatically.
    • FANUC Picture Diagnostics provides real-time visualization of motor current, temperature, and vibration spectra.

Application Scenarios

  • Hybrid CNC Machining Centers:
    • Drives a rotary axis (4Arms) and a linear feed axis (20Arms) in 5-axis milling machines for complex part manufacturing (e.g., aerospace components, automotive gearboxes).
  • Robotic Assembly Systems:
    • Controls a low-power wrist axis (4Arms) and a high-power arm axis (20Arms) in collaborative robots, ensuring ±0.05mm repeatability.
  • Printing and Packaging Machinery:
    • Enables precise tension control in reel-to-reel systems and rapid motion in pick-and-place units.
  • Medical Device Manufacturing:
    • Used in CNC lathes for producing orthopedic implants and surgical instruments with Ra 0.2μm surface finishes.
