The FANUC A06B-6164-H312#H580 is a βiSVSP 20/20/40-11 combined servo and spindle amplifier module used in compatible FANUC CNC drive systems.

Unlike a standard servo amplifier that controls only feed axes, this integrated module combines:

• Three servo amplifier channels
• One spindle amplifier channel
• Main power conversion
• FSSB servo communication
• Spindle feedback and control interfaces

FANUC documentation describes this configuration as a servo three-axis and spindle-motor amplifier for a spindle motor using an αiM or αiMZ sensor.

The three servo channels are identified as the L, M, and N axes. Their official rated output currents are:

• L Axis: 6.5 Arms
• M Axis: 6.5 Arms
• N Axis: 13 Arms

The corresponding servo current limits are 20 Apeak, 20 Apeak, and 40 Apeak. The supported servo output-frequency range is 0–400Hz.

The spindle channel has an official rated output current of 56 Arms, a base output frequency of 60Hz, and an output-frequency range of 0Hz–1kHz for the sensor-equipped H580 configuration.

The A06B-6164-H312#H580 is commonly searched for as a FANUC servo/spindle amplifier module, Beta iSVSP 20/20/40-11 amplifier, combined CNC servo spindle drive, or FANUC βiSVSP drive unit.

It is suitable for replacement when a confirmed amplifier fault causes servo-axis alarms, spindle alarms, failure of one or more motors to enable, unstable speed or positioning, FSSB communication errors, or damage to the internal control and power circuits.

The specifications above are taken from the FANUC βi series technical table for the exact A06B-6164-H312#H580 order specification.

Internal PCB References

FANUC documentation lists the following internal boards for the A06B-6164-H312#H580:

• Power PCB: A20B-2101-0582
• Control PCB: A20B-2101-0711
• Control PCB Module: A20B-2902-0671

These board numbers are useful when diagnosing whether the fault is located in the complete amplifier, power PCB, control PCB, or plug-in control module.

Cooling and AC Reactor References

FANUC documentation specifies the following associated components:

• Optional Cooling Fan Unit: A06B-6134-K001, one piece
• Recommended AC Reactor: A81L-0001-0155
• AC Reactor Rated Output: 11kW

The fan and reactor configuration should be checked against the original machine installation before replacement.

Compatibility Note

Before ordering the A06B-6164-H312#H580, please verify:

• Complete part number, including #H580
• Model marking βiSVSP 20/20/40-11
• Requirement for three servo axes and one spindle channel
• Spindle sensor type and feedback configuration
• Connected servo- and spindle-motor models
• 200–240VAC three-phase input
• FSSB and spindle-interface connections
• Original internal PCB numbers
• CNC parameters and motor-control settings
• Existing alarm codes and fault diagnosis

Do not confuse this model with A06B-6165-H312#H560. The latter has the same βiSVSP 20/20/40-11 capacity designation but is listed by FANUC as the sensor-less spindle configuration, while the A06B-6164-H312#H580 is the spindle-sensor version.

Common Use Cases

• FANUC βiSVSP 20/20/40-11 amplifier replacement
• Three-axis servo and spindle-drive maintenance
• Troubleshooting FSSB communication faults
• Diagnosis of servo or spindle motors that cannot enable
• Repair of unstable axis positioning or spindle speed
• Replacement of damaged power or control PCBs
• Restoration of combined FANUC drive systems
• Preparation of a tested spare amplifier for maintenance
