The FANUC A06B-6220-H022#H600 is an αiSP 22-B spindle amplifier module used in compatible FANUC CNC spindle-drive systems.

FANUC technical documentation identifies this exact order specification as the αiSP 22-B, part of the αi-B spindle amplifier family. It is also commonly listed in organic search results as a FANUC spindle drive, spindle amplifier module, Alpha iSP 22-B amplifier, or CNC spindle drive unit.

The amplifier receives control commands from the compatible CNC system and regulates the connected FANUC spindle motor during machine operation. It supports spindle acceleration, deceleration, speed control, orientation-related operation, and internal drive monitoring when correctly configured with the CNC and motor.

Published electrical specifications consistently identify the following ratings:

• Input Voltage: 283–339VDC
• Input Current: 89A at 283V
• Maximum Output Voltage: 240VAC
• Rated Output: 200VAC, 3-Phase
• Rated Output Current: 109A
• Spindle Output Frequency: 1Hz–1.5kHz

FANUC system documentation references the A06B-6220-H022#H600 as an iSP 22 spindle amplifier for applicable Series 30i-B configurations. Compatibility still depends on the complete CNC, spindle motor, power-supply module, software, and parameter setup.

It is suitable for replacing a confirmed faulty spindle amplifier associated with spindle alarms, failure of the spindle motor to start, unstable speed, abnormal amplifier status indications, orientation faults, or damage to the internal control and power circuits.

Cooling Fan Reference

FANUC maintenance documentation groups the A06B-6220-H022#H600 with the αiSP 22-B, 26-B, and 30-B models and lists the following cooling components:

• Internal Cooling Fan Motor: A90L-0001-0581
• Radiator Cooling Fan Motor: A90L-0001-0577

The complete fan unit and motor number should be checked against the amplifier edition before replacement.

Compatibility Note

Before ordering the A06B-6220-H022#H600, please verify:

• Complete FANUC order specification, including #H600
• Model marking αiSP 22-B
• CNC controller and spindle-system configuration
• Connected spindle motor model
• Power-supply module specification
• Original terminal and connector arrangement
• Amplifier hardware and software edition
• Spindle parameters and motor data
• Existing alarm code and fault diagnosis

Do not confuse A06B-6220-H022#H600 with A06B-6222-H022#H610. FANUC documentation lists both as αiSP 22-B specifications, but they belong to different hardware/order configurations and should not be treated as automatically interchangeable.

Common Use Cases

• FANUC αiSP 22-B spindle amplifier replacement
• CNC spindle-drive alarm troubleshooting
• Repair of a spindle motor that cannot start or enable
• Diagnosis of unstable spindle speed or abnormal output
• Troubleshooting spindle orientation and communication faults
• Replacement of damaged control or power circuitry
• Preparation of a tested spare spindle drive for maintenance
