The FANUC A06B-6093-H174 is a Beta SVU-80 standalone servo amplifier from the 2nd generation I/O Link series. Designed as a single-axis drive unit with built-in power supply, it delivers 18.9 Arms rated output current with 80 Apeak current limiting capability. The unit communicates via the I/O Link protocol through a Power Motion Manager (PMM) and is compatible with FANUC Beta b22/2000 servo motors. It integrates with FANUC 15, 16, 18, 20, 21, and i series CNC controls, making it suitable for auxiliary axis applications such as ATC mechanisms, turret indexers, and pallet changers on machine tools. With a compact 45mm width, it can be mounted anywhere on the machine. The unit includes internal wiring board A20B-2100-0291 / A16B-3200-0291 and control PCB A20B-2100-0187. Note: This model has been discontinued by FANUC and superseded by the 6132 Beta i I/O Link series.
Q: What is the difference between SVU-80 and SVU-40?
A: The SVU-80 (A06B-6093-H174) has a rated output of 18.9 Arms / 80 Apeak, while the SVU-40 (A06B-6093-H173) is rated at 12 Arms / 40 Apeak. The SVU-80 drives larger Beta motors such as b22/2000.
Q: What CNC controls are compatible with the A06B-6093-H174?
A: It is compatible with FANUC 15, 16, 18, 20, 21, and i series controls.
Q: Can the A06B-6093-H174 be replaced by a newer model?
A: Yes, but not directly. FANUC has discontinued this series and replaced it with the 6132 Beta i I/O Link series. Replacement requires changes to wiring and CNC configuration.
Q: What does I/O Link interface mean?
A: The I/O Link is FANUC's serial communication protocol between the CNC and servo amplifier, running through a PMM (Power Motion Manager). It allows the amplifier to be mounted anywhere on the machine without PWM cables running back to the CNC.
Q: What are the internal PCBs included?
A: The unit includes the A20B-2100-0187 control PCB and A20B-2100-0291 / A16B-3200-0291 wiring board. These are not sold separately.
