A06B-6089-H104

The A06B-6089-H104 is a single-axis AC servo amplifier (SVU1-40) in the FANUC Alpha series, designed for high‑performance motion control in CNC machines. It works with FANUC Alpha servo motors and connects to 0i‑C/D, 16i/18i/21i‑A/B CNC systems via fiber‑optic links.

Description

General Description

The A06B-6089-H104 is a single-axis AC servo amplifier (SVU1-40) in the FANUC Alpha series, designed for high‑performance motion control in CNC machines. It works with FANUC Alpha servo motors and connects to 0i‑C/D, 16i/18i/21i‑A/B CNC systems via fiber‑optic links.

Specifications

Electrical
  • Input: Three‑phase 200–230VAC, 50/60Hz; 13.4A at 200V.

  • DC bus: 283–325VDC (from PSM power supply module).

  • Max output voltage: 230VAC.

  • Rated output current: 12.5A (L‑axis); peak 40A.

  • Rated output power: 4.4kW.

  • Regenerative discharge capacity: 100W (no wind).

Mechanical & Environmental
  • Mounting: Vertical in control cabinet.

  • Cooling: Internal fan (forced air).

  • Operating temperature: 0°C to 55°C.

  • Dimensions: 150mm (W) × 380mm (H) × 307mm (D).

  • Weight: 5kg.

Compatibility
  • Motors: FANUC Alpha series (αi‑B, α) servo motors.

  • CNC: 0i‑C/D, 16i/18i/21i‑A/B, Power Mate.

  • Interface: PWM Type A/B (set via front switch).

Key Features

  • High‑precision current/speed/position control with HRV (High‑Response Vector) control.

  • Compact, rugged design for industrial vibration resistance.

  • Built‑in 7‑segment LED display and diagnostic LEDs for real‑time status and fault indication.

  • Multiple protection: overcurrent, overvoltage, undervoltage, overtemperature, fan fault, IPM fault.

  • Regenerative braking feeds energy back to the power supply, improving efficiency.

Common Alarms

  • AL‑01: Overvoltage (HV) – DC bus too high.

  • AL‑02: Low control voltage (LV) – control power supply low.

  • AL‑05: Over‑regenerative discharge (DCOH) – regen energy excessive.

  • AL‑06: L‑axis overcurrent (HCM) – motor current too high.

  • AL‑08: L‑axis IPM alarm (IPML) – power module fault.

Installation & Safety Notes

  • Disconnect all power before installation or maintenance.

  • Verify the “CHARGING” LED is off before handling to avoid electric shock.

  • Provide ≥50mm clearance around the unit for airflow.

  • Tighten mounting screws securely to prevent vibration issues.

  • Periodically inspect fan operation, terminal tightness, and heat sink cleanliness.

  • If an alarm occurs, stop the machine immediately and check motor, wiring, and PSM.

Application Range

  • High‑speed, high‑precision CNC machining centers, heavy‑duty lathes, grinders, and multi‑axis robots.

  • Suitable for single‑axis high‑power applications requiring precise motion control.
