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 US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This FANUC dual-axis module from the 6117 iSV family is a servo amplifier that drives two coordinated feed axes and manages closed-loop feedback over the FSSB optical fiber link. Positioned between the i-series CNC and Alpha i servo motors, it serves as a reliable replacement unit or spare part for maintenance teams supporting FANUC-controlled machining centers, turning machines and robot axes.

The iSV2-20/20 rating provides two channels in one compact frame for machines running FANUC 30i and related i-series controls. It works with FANUC Alpha i servo motors with serial feedback and fits into the Alpha i rack alongside the matched power supply and DC bus. In field service, matching rating and series allows a clean drop-in replacement that helps restore axis motion and clear servo alarms caused by a failed channel or intermittent trips under load.

The fiber-based FSSB link supports stable communication in cabinets exposed to electrical noise from high spindle loads, welding equipment or long motor leads. The two-axis format also helps reduce cabinet space and simplifies industrial spare inventory planning for plants running multiple machines on the same drive platform.

Reference: A06B-6117-H205

Manufacturer: FANUC

Product type: FANUC Servo Drive 6114 6117 iSV

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

Applications: CNC machining centers, lathes, gantry axes and FANUC robot axes using i-series controls including 30i

Key technical data: Alpha iSV2-20/20 two-axis module, FSSB fiber-optic interface to FANUC i-series, compatible with Alpha i motors with serial feedback, integrates in the Alpha i rack with the appropriate PSU and DC bus, Japan build quality, supplied as a tested unit with warranty, available as a replacement, refurbished unit, exchange service or repair service depending on maintenance strategy.

On the production floor this model is commonly selected to replace a faulty drive channel that triggers axis alarms or nuisance trips during acceleration. Keeping a stocked spare on the shelf allows a quick field swap during a planned stop, limiting machine downtime while the removed amplifier goes out for repair service or analysis.

For life-extension or retrofit work, staying with the same series and the iSV2-20/20 rating avoids cabling changes and preserves established motor selections. Many shops standardize on this module as a drop-in replacement for X, Y or auxiliary axes across multiple FANUC i-series machines.

Each Fanuc Servo drive is functionally tested on CNC simulators with FANUC Alpha i servo motors by skilled engineers, then packaged with protective foam, antistatic materials and connector caps to protect the fiber port and power terminals. A warranty is included. Many stocked items ship directly from our Florida facility, with worldwide industrial shipping available.

This unit also serves as an effective emergency spare part for older FANUC installations where sourcing time is critical. Cnc-shopping USA supports obsolete part requests and can assist with exchange service, refurbished unit options or repair service to keep legacy i-series machines running.

Frequently asked questions about A06B-6117-H205:

Is this module compatible with FANUC 30i controls?
Yes. It links to the CNC over the FSSB optical fiber network used by FANUC i-series controls, including 30i. Match the same rack architecture and PSU used on the machine.

Which motors does the iSV2-20/20 work with?
It is designed for FANUC Alpha i servo motors that use serial feedback. Use the same motor class and ratings as the original build for a direct field replacement.

Can I substitute a different iSV2 rating?
Stay with the same series and the 20/20 rating (A06B-6117-H205)  to maintain power capability and parameter compatibility. Mixing ratings can create mismatches in current capacity and setup.

What should I check during a field swap?
Verify FSSB fiber condition and orientation (your FANUC A66L Optic fiber cable), confirm the DC bus and Servo motor power connections match the original layout and inspect cabinet cooling and grounds before power-up.

Do you offer exchange or repair options for this reference?
Yes. Depending on availability you can source a replacement unit, arrange an exchange service or request a repair service to support your maintenance plan.
