Description

FANUC A06B-6114-H211 – Alpha i Dual-Axis Servo Amplifier

Product Overview

The FANUC A06B-6114-H211 is an Alpha i series dual-axis servo amplifier module, identified as the SVM2-160/160i. It is designed for FANUC CNC servo systems and provides power amplification for two servo axes, converting the DC bus supply into controlled motor output for precise machine motion. FANUC documentation lists the H211 configuration as the SVM2-160/160i model, while available technical references specify approximately 39 A output capability for both the L and M axes.

The module is intended for CNC machine tools and other FANUC-controlled motion systems where accurate positioning, acceleration, deceleration, and speed regulation are required. The amplifier communicates with the CNC control through the FANUC servo interface, including fiber-optic communication in the Alpha i architecture. For replacement work, the exact amplifier designation, connected motor ratings, axis assignment, and system generation should be verified before installation.

Key Features and Benefits — A06B-6114-H211

• Two-axis servo amplification for FANUC CNC applications.
• Alpha i SVM2-160/160i architecture.
• Supports high-current servo motor operation.
• 39 A rated output capability for both L and M axes.
• Designed for precise closed-loop CNC motion control.
• Fiber-optic communication supports the FANUC CNC servo architecture.
• Integrated cooling arrangement supports continuous industrial operation.
• Suitable for CNC machine-tool maintenance and replacement applications.

The dual-axis configuration is particularly useful in machines where two servo axes can be controlled from one amplifier module, reducing cabinet space and simplifying the servo power architecture.

Installation and Maintenance — A06B-6114-H211

Before replacement, verify the CNC control model, servo amplifier configuration, motor part numbers, axis assignment, DC bus voltage, and fiber-optic communication connections. Record the original amplifier’s part number and revision before removal.

Because this is a high-power servo amplifier, DC-bus discharge time and the machine manufacturer’s electrical isolation procedure must be observed. Inspect cooling fans, heat sinks, connectors, power terminals, and fiber-optic cables for contamination or damage.

After installation, verify amplifier initialization, axis communication, motor feedback, alarm status, and axis movement under controlled commissioning conditions. Do not assume that a physically similar SVM2 module is electrically interchangeable; the rated current and axis configuration must match the application.

Product Warranty — A06B-6114-H211

Warranty coverage depends on supplier, product condition, and purchase agreement. For critical CNC spare inventory, confirm the exact FANUC part number, hardware revision, tested condition, serial-number traceability, and warranty terms before procurement.

The FANUC A06B-6114-H211 is a high-current, dual-axis Alpha i servo amplifier intended for demanding CNC motion-control applications. Personally, I would verify both connected servo motor ratings before approving a replacement; matching the amplifier alone does not guarantee a correct system configuration.
