A06B-6141-H022#H580 Fanuc Spindle Drive Alpha iSP22

Buy online your A06B-6141-H022#H580 Fanuc Spindle Drive Alpha iSP22 reference A06B-6141-H022-580 from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This is a FANUC Alpha iSP22 spindle amplifier module for the 200V class, used to drive and regulate FANUC Alpha i spindle motors under CNC command. It functions as the spindle power interface in the drive chain, delivering controlled current to the motor for reliable speed and torque control during cutting, threading and high-speed indexing. Commonly sourced as a replacement unit or spare part for FANUC-equipped machine tools, it is suited for field replacement when the same rating and option code are required.

The module manages the spindle motor’s acceleration, deceleration and steady-state operation based on CNC setpoints and feedback. It installs in the electrical cabinet alongside the matching FANUC power supply and servo modules used on Alpha i systems. The iSP22 rating is sized for applications that need robust current delivery for steel machining, heavy starts and frequent spindle reversals, provided the machine builder specified this class. It is a complete assembly with power section and control PCB, supplied ready to integrate in a correctly configured FANUC Alpha i cabinet.

Key electrical data for this reference include a rated input of 283 to 339 V, 25.2 kW, and a rated output current of 95 A. In practical terms this supports demanding spindle cycles with consistent thermal behavior when installed in a cabinet with proper airflow and within the original OEM specification. The #H580 variant follows FANUC’s option code scheme, so matching the suffix with the machine’s BOM is important for a true drop-in swap with A06B-6141-H022 units used in 200V-class installations.

Built for FANUC Alpha i environments across machining centers, lathes and grinders, this amplifier is typically paired with the designated Alpha i spindle motor size defined by the machine builder. It is manufactured in Japan and is suitable for both direct replacement and retrofit projects where the original rating and voltage class must be preserved.

Reference: A06B-6141-H022/H580

Manufacturer: FANUC

Product type: FANUC Spindle drive

Main function: AC spindle amplifier for FANUC Alpha i systems, governing spindle speed and torque under CNC control.

Applications: FANUC-controlled CNC machine tools using Alpha i spindle systems in 200V cabinets, including machining centers, turning machines and grinding equipment when specified for the 22 class.

Key technical data: Alpha iSP22 200V class module with rated input 283 to 339 V at 25.2 kW, rated output current 95 A, complete with power board and control PCB, including the #H580 software, designed for use in FANUC servo and spindle drive cabinets, manufactured in Japan, listed for immediate shipment on our platform. Many stocked items ship directly from our Florida facility.

On the production floor this unit is commonly used to restore spindle operation after alarms related to overcurrent, blown power stages or control faults. Maintenance teams typically keep at least one stocked spare for critical machines so a field replacement can be performed with minimal downtime when the same reference and suffix are required. For planned overhauls, it can be integrated during scheduled stops to extend machine lifetime within the original drive topology.

For quality assurance, each tested unit is verified by skilled engineers on CNC simulators with Fanuc servo motors to confirm proper drive enable, commutation and command response. Units are packed in protective industrial packaging suitable for carrier handling, and they include a warranty as indicated on the product page. Depending on availability, products are commonly dispatched from our Florida warehouse.

This Fanuc module can serve as an emergency spare for unplanned failures, especially where the original amplifier is now an obsolete part or has long repair turnaround. Cnc-shopping USA supports repair service and may offer exchange service or refurbished unit options to keep legacy FANUC installations running with dependable spindle control.

Frequently asked questions about A06B-6141-H022#H580:

Is this a direct drop-in for A06B-6141-H022 with a different suffix?
It is a drop-in replacement when the #H580 Software option code, voltage class and rating match the original BOM. Always verify the full code on the machine’s nameplate and Fanuc maintenance manual documentation before ordering.

Which spindle motors does the iSP22 rating support?
It is used with FANUC Alpha i spindle motors specified by the OEM for the 22 class within the same 200V architecture. Pair it only with the motor and power supply combination defined by the machine builder.

Can it replace iSP11 or iSP30 modules?
No. Use the exact amplifier rating specified for the machine. Substituting different iSP sizes can lead to incorrect current capability or protection behavior.

Does it include the control PCB and power sections?
Yes. This reference is supplied as a complete spindle amplifier assembly with its power board and control PCB, ready for integration in a compatible FANUC Alpha i cabinet.

What should be checked before installation?
Confirm the reference and suffix, the 200V class, cabinet interface, and that the motor and power supply ratings match. Keep the machine’s maintenance records available for any required parameter checks during commissioning.
