The FANUC A06B-6240-H207 is an αiSV 40/40-B dual-axis servo amplifier module used in compatible FANUC CNC servo systems.

FANUC documentation classifies this model as a 200V input-series, two-axis αi-B servo amplifier. It controls two servo axes and communicates with the CNC through the FSSB fiber-optic servo interface.

For both the L-axis and M-axis, the official specifications list a rated output current of 13 Arms and a nominal current limit of 40 Apeak. The supported servo output frequency range is 0–550 Hz.

The A06B-6240-H207 is commonly searched for as a FANUC servo amplifier module, AiSV 40/40-B servo drive, dual-axis servo amplifier, or Alpha i-B servo drive.

It is suitable for replacement when a confirmed amplifier fault causes servo alarms, failure of one or both axes, unstable motor control, FSSB communication errors, abnormal amplifier status indications, or failure to enable the connected servo motors.

Referenced CNC Systems

FANUC documentation lists the αiSV-B amplifier family for applicable configurations within these control families:

• FANUC Series 30i-B
• FANUC Series 31i-B
• FANUC Series 32i-B
• FANUC Series 35i-B
• FANUC Power Motion i-Model A
• FANUC Series 0i-Model D

This is a series-level reference and does not mean the A06B-6240-H207 is automatically compatible with every machine using one of these controls.

Compatibility Note

Before ordering the A06B-6240-H207, please verify:

• Complete servo amplifier part number
• Model marking αiSV 40/40-B
• Two-axis amplifier requirement
• 200V-class servo system
• Original connector and terminal arrangement
• FSSB communication configuration
• Connected servo-motor models
• CNC parameters and amplifier software configuration

Do not confuse A06B-6240-H207 with A06B-6290-H207. The latter is the αiSV 40/40HV-B 400V-class model and is not the same amplifier.

Common Use Cases

• FANUC αiSV 40/40-B amplifier replacement
• Dual-axis CNC servo-drive maintenance
• Troubleshooting alarms affecting one or both axes
• Repair of FSSB communication faults
• Diagnosis of unstable servo-motor operation
• Replacement of a physically damaged amplifier module
• Preparation of a tested spare drive for machine maintenance
