FANUC A06B-6320-H364 Servo Spindle Amplifier 80/80/80-18-B for CNC Machine Tools

The FANUC A06B-6320-H364 is a Beta i-B Series integrated servo and spindle amplifier module for CNC machine-tool drive systems.

Its amplifier designation is Beta i SVSP 80/80/80-18-B. The module combines three servo amplifier channels and one spindle amplifier section in a single cabinet-mounted drive unit. This integrated architecture reduces the number of separate drive modules required inside a compatible CNC electrical cabinet.

The three servo channels are identified by the 80/80/80 designation, while the spindle section is identified by the 18 designation. The exact connected motor combination must be confirmed from the original machine documentation and amplifier configuration before replacement.

The module operates from a three-phase 200 to 240 VAC supply at 50 or 60 Hz. Available nameplate data identifies a rated input current of 82 A at 200 VAC.

The A06B-6320-H364 is used to control compatible FANUC servo axes and an AC spindle motor within the same CNC drive architecture. It is not a synchronous servo motor, standalone PLC, I/O module, POWERLINK device, or general-purpose frequency inverter.

Installation Notes

Confirm that the original amplifier model is A06B-6320-H364 before replacement.

Check the complete nameplate, including the Beta i SVSP 80/80/80-18-B designation, input-voltage class, motor models, servo-axis assignments, spindle motor, feedback cables, and CNC parameters.

Do not use A06B-6320-H223 as a direct substitute without engineering confirmation. It is a different Beta i SVSP amplifier configuration.

Before removing the original unit, record the cable positions and back up applicable CNC and drive parameters.

Verify the following before commissioning:

Main power wiring

Servo motor connections

Spindle motor connection

Feedback cable assignment

Cooling fans

Grounding and shielding

CNC communication wiring

Alarm status

Axis movement and spindle rotation
