The FANUC A06B-6117-H103 is an Alpha iSV 20 (αi SV-20) single-axis servo amplifier module designed for high-precision CNC and industrial automation systems. It accepts 283–339V DC input at 2.5 kW and delivers 240V AC output with a rated 6.5A for the L-axis. The unit uses the FSSB (FANUC Serial Servo Bus) interface for communication with the CNC control, supporting the latest generation FANUC 30i, 31i, and 32i series controls. Weighing 7.0 kg, this amplifier is built to FANUC's stringent standards with built-in overcurrent, overvoltage, and thermal protection. It is CE certified and manufactured in Japan, suitable for demanding machine tool spindle and feed axis applications requiring smooth, reliable motion control.
Q: What CNC controls is the A06B-6117-H103 compatible with?
A: It is designed for the latest generation FANUC CNC controls: 30i, 31i, and 32i series.
Q: What is FSSB interface?
A: FSSB (FANUC Serial Servo Bus) is FANUC's high-speed optical fiber-based communication protocol between the CNC controller and servo amplifiers, providing deterministic real-time motion control.
Q: What is the difference between Alpha iSV and Beta SVU?
A: Alpha iSV is the latest generation with FSSB fiber-optic interface for high-end CNC controls (30i/31i/32i), while Beta SVU (6093 series) uses I/O Link for auxiliary axes on older controls (15/16/18/21/i series).
Q: Can this amplifier drive multiple axes?
A: No, the A06B-6117-H103 is a single-axis amplifier for the L-axis only.
Q: What does the 2.5 kW rated input power mean?
A: The amplifier draws up to 2.5 kW of DC power from the CNC power supply unit to drive the connected servo motor.
