FANUC A06B-6079-H105 Servo Amplifier Module with 4-axis Control 80 A per Axis and HSSB Communication
The FANUC A06B-6079-H105 is a high-power, multi-axis servo amplifier module from FANUC's αiSV80-4i series, designed for demanding CNC machine tool and industrial robotics applications. This unit provides precise current and velocity control for up to four AC servo motors, delivering exceptional torque stability, fast dynamic response, and seamless integration with FANUC's high-speed serial servo bus (HSSB).
Built for heavy-duty continuous operation, the A06B-6079-H105 is commonly used in large machining centers, transfer lines, multi-axis robots, and automated material handling systems. Its modular design allows easy mounting in FANUC's αi series drive cabinets, with shared DC bus and regenerative braking for energy-efficient multi-axis control.
