FANUC A06B-6320-H332 is a βiSVSP40/40/40-11-B integrated servo and spindle amplifier for compatible FANUC CNC machine tools. It combines power conversion, three servo-axis channels and one spindle channel in a 260mm-wide module.

The unit provides three 40-class servo channels with 13Arms rated output per axis and an 11kW-class spindle channel rated at 56Arms.

A06B-6320-H332 Product Specifications

Integrated Three-Axis and Spindle Control

The module controls three CNC feed axes and the machine spindle. FSSB carries servo commands and feedback data, while the spindle section manages speed and position feedback according to the installed CNC, motor and sensor configuration.

Model and Replacement Compatibility

Match the complete A06B-6320-H332 nameplate. H333 is the related 40/40/40-15-B version with different spindle capacity; H312 is a 20/20/40-11-B model. A06B-6321-H332 has the same channel designation but uses a narrower 180mm construction, so it is not an automatic physical replacement.

Testing and Installation Notes

REACO CNC checks the nameplate, power stage, DC link, three servo channels, spindle channel, FSSB, cooling and alarms as applicable. Confirm the motors, feedback devices, connectors, AC supply and CNC parameters.

Qualified personnel must isolate power and verify the charge indicator is off before handling. Related resources: FANUC servo and spindle drives and FANUC CNC drive repair service.
