The FANUC A06B-6240-H106 is an αiSV 160-B single-axis servo amplifier module designed for compatible FANUC CNC servo systems.

FANUC documentation classifies this model as part of the αiSV-B 200V input series. It provides servo-motor power and control for one axis and communicates with the CNC through the FANUC servo interface.

The amplifier has an official rated output current of 45 Arms, with a nominal current limit of 160 Apeak. Its supported servo output frequency range is 0–550 Hz.

The A06B-6240-H106 is widely searched for as a FANUC servo amplifier module, AiSV 160-B servo drive, Alpha i-B servo amplifier, or single-axis CNC drive.

It is suitable for replacing an amplifier with confirmed servo alarms, unstable motor operation, failure to enable the axis, internal communication faults, abnormal status indications, or damaged power and control circuitry.

Referenced CNC Systems

FANUC documentation lists the αiSV-B amplifier family for applicable configurations within the following 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

These are series-level references. Compatibility with a particular machine still depends on its complete CNC specification, connected servo motor, software, parameters, and amplifier configuration.

Technical Clarification

The 17W value sometimes shown in product databases is not the rated motor power or amplifier output power.

In the FANUC heat-dissipation calculation table, the A06B-6240-H106 / αiSV 160-B has:

• Base heat-dissipation value: 17W
• HRV2 coefficient: 4.1 W/Arms
• HRV3 coefficient: 5.3 W/Arms
• HRV4 coefficient: 7.6 W/Arms

These figures are used for cabinet thermal calculations and should not be presented as the amplifier’s output-power rating.

Compatibility Note

Before ordering the A06B-6240-H106, please verify:

• Complete FANUC amplifier part number
• Model marking αiSV 160-B
• Single-axis amplifier requirement
• 200V-class servo-system configuration
• Connected FANUC servo-motor model
• Original connectors and terminal layout
• CNC control model and FSSB configuration
• Amplifier software and CNC parameter settings

Do not confuse A06B-6240-H106 with A06B-6240-H126. Both are listed as αiSV 160-B, but the H126 is a later configuration supporting connection to the Servo Safety Module, so direct interchangeability should be confirmed before replacement.

Common Use Cases

• FANUC αiSV 160-B amplifier replacement
• Single-axis CNC servo-drive maintenance
• Diagnosis of servo amplifier startup failures
• Repair of unstable or non-responsive axis operation
• Troubleshooting FSSB communication faults
• Replacement of damaged control or power circuitry
• Preparation of a tested spare drive for machine maintenance
