FANUC A06B-6240-H208 is a two-axis αiSV 40/80-B servo amplifier module in the FANUC SERVO AMPLIFIER αi-B Series. Designed for 200V-class CNC drive systems, it controls two compatible AC servo motors through separate L and M outputs.

The 40/80 designation identifies nominal peak-current classes, not continuous output current. FANUC specifies 13 Arms with a 40 Apeak limit for the L axis and 22.5 Arms with an 80 Apeak limit for the M axis. It is also searched as A06B6240H208.

A06B-6240-H208 Product Specifications

Dual-Axis αiSV Servo Control

A06B-6240-H208 uses FANUC FSSB communication to receive CNC commands and regulate current, speed and position for two machine axes. The αiSV-B platform is documented for selected FANUC 30i, 31i, 32i, 35i-B, Power Motion i-A and 0i-D systems; compatibility still depends on the complete machine configuration.

Motor and Replacement Compatibility

Confirm the full A06B-6240-H208 nameplate, L/M motor models, αiPS power supply, FSSB connection, feedback devices, connectors, software and servo parameters. Do not substitute A06B-6240-H207, H209 or H210 based on appearance; their current combinations differ.

Testing and Installation Notes

REACO CNC checks the label, housing, connectors, fans, control boards, power stages, FSSB communication, alarms and both servo channels as applicable. Back up parameters before replacement. Qualified personnel must isolate power and allow the DC link to discharge before installation.
