The FANUC A06B-6240-H126 is an αiSV 160-B single-axis servo amplifier module used in compatible FANUC CNC servo systems.

FANUC technical documentation identifies the A06B-6240-H126 as an upgraded version of the αiSV-B 200V-series single-axis amplifier. It also supports connection to an SSM, distinguishing it from some earlier αiSV 160-B configurations.

The amplifier provides power and control for one servo axis. It is commonly searched for as a FANUC AiSV 160-B servo amplifier, Alpha i-B servo drive, single-axis servo amplifier module, or CNC servo drive.

Published specifications consistently list an input range of 283–339VDC, a maximum output voltage of 240VAC, an output current of 45A for one axis, and an output frequency range of 0–550Hz.

The A06B-6240-H126 is suitable for replacing a confirmed faulty amplifier associated with servo alarms, failure to enable the axis, unstable motor control, abnormal amplifier indications, or damaged control and power circuitry.

Compatibility Note

The A06B-6240-H106 and A06B-6240-H126 are both identified as αiSV 160-B amplifiers, but FANUC documentation lists H126 separately as an upgraded specification with SSM connection support. They should not be treated as automatically interchangeable without checking the complete machine configuration.

Before ordering, please verify:

• Complete FANUC amplifier part number
• Model marking αiSV 160-B
• H106 or H126 specification
• SSM connection requirement
• Single-axis and 200V-class configuration
• Connected FANUC servo motor model
• Original terminal and connector arrangement
• CNC parameters and servo-system configuration
• Hardware revision shown on the original unit

Common Use Cases
