A06B-6117-H205 Fanuc Servo Amplifier Alpha iSV 2-20/20 30i

Buy online your A06B-6117-H205 Fanuc Servo Amplifier Alpha iSV 2-20/20 30i reference A06B-6117-H205 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This FANUC Alpha iSV dual-axis servo amplifier from the 6117 iSV family drives two feed axes in FANUC i-series CNC systems and robotics. Positioned between the CNC and the Alpha i servo motors, it handles power output and closed-loop control via the FSSB fiber-optic interface, making it a dependable CNC replacement component for maintenance teams managing FANUC-based machines.

The iSV2-20/20 variant supports two coordinated axes in one compact module, commonly used on machining centers, lathes and gantry equipment running FANUC 30i and other i-series controls. It communicates with the CNC over FSSB and works with FANUC Alpha i servo motors equipped with serial feedback, allowing consistent axis tuning and stable operation across a wide range of machine-tool platforms.

Integration is straightforward for field replacements when the existing unit matches the same rating and series. The module fits the Alpha i rack environment with the appropriate power supply unit, power bus and motor power connectors. When sourced as a replacement unit or refurbished unit, it is typically selected to clear axis alarms caused by a failed servo channel, restore motion on X, Y or auxiliary axes and support preventive maintenance on older FANUC installations.

For robot cells and handling equipment using FANUC i Control, this amplifier provides two-axis drive capability in a single frame, reducing footprint while simplifying spare inventory. The optical FSSB link helps reduce electrical noise issues on the production floor, which is valuable in environments with high spindle loads, welding equipment or long cable runs.

Manufacturer: FANUC

Product type: FANUC Servo Drive 6114 6117 iSV

Main function: Dual-axis servo amplification and feedback processing for FANUC Alpha i feed motors over FSSB

Applications: CNC machining centers, turning machines, gantry axes and FANUC robot axes using i-series controls

Key technical data: Alpha iSV2-20/20 dual-axis module, FSSB optical fiber interface to FANUC i-series including 30i, compatible with FANUC Alpha i servo motors with serial feedback, Japan build quality, supplied as a tested unit with warranty, suitable for replacement, exchange service or repair service depending on maintenance strategy.

In day-to-day maintenance, this model is commonly used to replace a faulty drive channel that triggers axis alarms or intermittent trips under load. Keeping a stocked spare on the shelf enables a quick swap during planned stops and helps minimize machine downtime while the removed unit goes through repair service or analysis.

For retrofit or life-extension projects, matching the exact rating, series and FSSB interface ensures a clean drop-in swap without reworking cabling or motor selections. Many shops maintain at least one industrial spare inventory unit for machines that run extended shifts or critical production schedules.

Each drive is functionally tested on CNC simulators with FANUC Alpha i servo motors by skilled engineers. Units are packed with protective foam, antistatic materials and connector protection to safeguard the fiber port and power terminals during transit. A warranty is provided, and packaging is prepared for worldwide industrial shipping.

This module is suitable as an emergency spare part for aging FANUC systems where sourcing can be time-sensitive. Cnc-shopping supports obsolete part requests and can assist with exchange service, refurbished unit options or repair service to keep legacy FANUC i-series machines running with reliable motion control.

Frequently asked questions about A06B-6117-H205:

Which controls does this amplifier work with?
It links over FSSB to FANUC i-series controls, including 30i and related i-model CNCs. It is also used in FANUC robot applications that rely on FSSB-connected Alpha i drives.

What motors are supported?
It is designed for FANUC Alpha i servo motors with serial feedback. Use the same motor class and rating as the original installation for a direct field replacement.

Can it replace other iSV2 modules with different ratings?
Stay with the same series and rating to avoid mismatches in power capability and parameters. If the original label shows iSV2-20/20, select the same to maintain performance and compatibility.

Do I need special cables for the optical link?
Use the appropriate FANUC FSSB fiber-optic cable length and type specified for the machine. Inspect connectors and fiber ends during replacement to avoid link faults after power-up.
