A06B-6122-H030#H550 Fanuc Spindle amplifier SPM-30HVi

Buy online your A06B-6122-H030#H550 Fanuc Spindle amplifier SPM-30HVi reference A06B-6122-H030-H550 from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

This FANUC module is a SPM-30HVi spindle amplifier used in the FANUC αi drive platform. It regulates spindle speed and torque command from the CNC, supplies controlled power to the spindle motor, and maintains stable machining at low and high RPM. Suitable as a replacement unit or spare part for service teams managing FANUC-equipped machine tools.

The unit operates within the FANUC αi drive system where a matching power supply module feeds the shared DC link. The amplifier handles current control and speed loops for the spindle motor and supports spindle orientation functions commanded by the CNC. Typical use is in vertical machining centers, turning centers and grinding machines running FANUC Series i controls.

Integration follows the standard FANUC cabinet layout with the SPM mounted alongside servo amplifiers and the power supply module. The option suffix H550 identifies a defined Software configuration that must align with the machine build and parameters. Technicians usually verify the unit label, option code and connector layout before a field replacement to ensure a drop-in fit.

Because it is part of the αi family, this amplifier pairs with compatible FANUC αi spindle motors and communicates within the FANUC drive system managed by the CNC. Correct matching of capacity, firmware level and option code helps maintain stable acceleration, deceleration and spindle orientation without rework on wiring.

Reference: A06B-6122-H030-H550

Manufacturer: FANUC

Product type: FANUC Spindle drive

Main function: Controls and powers the FANUC αi spindle motor, providing closed-loop spindle speed and torque regulation under CNC command.

Applications: Field replacement in FANUC-driven machining centers, lathes and grinders using Series i controls in maintenance, repair and retrofit contexts.

Key technical data: Model SPM-30HVi code A06B-6122-H030 with option H550, Japan made. Works within the αi drive platform on a shared DC bus with a matching FANUC power supply module. Designed for cabinet mounting near αi servo amplifiers. Commonly sourced as a CNC replacement component for planned spares and emergency repairs, with fast dispatch depending on availability.

In real maintenance conditions this model is used to restore machines with spindle alarms, power stage faults or unstable spindle regulation. Keeping a tested unit on the shelf shortens downtime during unplanned stops and supports preventive maintenance programs on older FANUC cabinets. Many shops standardize on this code to simplify troubleshooting and reduce restart time after a failure.

Each drive is checked by skilled engineers on CNC simulators with spindle motors to confirm current control, speed response and interface behavior before shipment. Units are packed in antistatic protection with foam bracing for industrial transport and covered by our standard warranty terms. Repair service and exchange service may also be available based on condition and turnaround needs.

For legacy equipment this module can act as an emergency spare to reduce unexpected downtime. Cnc-shopping supports sourcing of obsolete parts and offers options for refurbished units when appropriate, helping keep older FANUC installations productive with reliable spare-part support and worldwide shipping.

Frequently asked questions about A06B-6122-H030-H550:

Is the H550 option mandatory when replacing an existing SPM-30HVi?
Yes, match the option code to the original nameplate. The #H550 suffix defines the Fanuc software for this spindle amplifier hardware configuration details used by the machine builder, so using the same #H550 code helps ensure a direct swap without wiring or parameter mismatches.

Which power supply module should be used with this amplifier?
Use a compatible FANUC αi power supply such as A06B-6120-Hxxx sized to your cabinet and spindle load. Check the machine’s drive list and the power supply nameplate to confirm DC bus compatibility and capacity.

Will I need to transfer spindle parameters after replacement?
Spindle-related settings are stored in the CNC and must be consistent with the installed amplifier and motor. Back up parameters before removal and verify spindle orientation and acceleration limits after installation.

Can this code be used on machining centers and turning centers with FANUC Series i controls?
This model is commonly found in both applications when the machine is built on the FANUC αi drive platform. Confirm the exact code against the machine documentation and drive layout to validate compatibility.

What checks help confirm a healthy amplifier before running production?
Verify cooling airflow (your FANUC A90L fans), cabinet grounding, connector seating and alarm-free power up. Run a controlled spindle speed sweep without load, then confirm orientation and braking behavior according to the machine manual.
