A06B-6122-H011#H570 Spindle drive Fanuc SPM-30HVi #H570

Buy online your A06B-6122-H011#H570 Spindle drive Fanuc SPM-30HVi #H570 from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The FANUC A06B-6122-H011#H570 is a spindle drive module from the SPM-30HVi family designed to control FANUC αi high-voltage spindle motors in CNC machine tools. It regulates spindle speed and torque under CNC command, ensuring stable acceleration, deceleration, and spindle orientation during machining operations.

This module operates within the FANUC αi HV system and works with a shared DC bus and the corresponding power supply module. It is commonly used on machining centers, CNC lathes, and grinders equipped with FANUC control systems, where reliable spindle performance and precise speed regulation are essential.

The drive is integrated into cabinet-mounted FANUC αi systems and is widely used with 0i and 30i series CNC controls through FANUC's high-speed communication interface. The H570 suffix identifies a specific option configuration defined by FANUC and should be matched with the original nameplate to ensure full compatibility during replacement.

This spindle amplifier belongs to the SERVO AMPLIFIER αi SERIES – αi SP 11HV range. It operates with an input voltage of 565 to 679 V, delivers 13.2 kW of power, and provides a rated output of 480 V at 23 A. The module is equipped with a Type B interface and is designed for installation in enclosed industrial electrical cabinets.

In maintenance applications, the A06B-6122-H011#H570 is frequently selected to replace faulty spindle amplifiers that cause drive alarms, unstable spindle speed, or complete spindle failure. When installed as a like-for-like replacement with the correct option code and rating, it can usually restore machine operation without significant parameter adjustments.

This module is also used in retrofit and lifecycle maintenance programs where the original FANUC αi HV architecture is retained and only the defective drive is exchanged. Keeping a tested unit in spare inventory helps reduce machine downtime and supports rapid recovery during unexpected failures.

Each drive can be inspected and tested on dedicated CNC test benches to verify communication, current output, and operational performance before shipment. Protective anti-static packaging and industrial-grade cushioning ensure safe transportation. The FANUC A06B-6122-H011#H570 is a reliable replacement solution for maintaining and extending the service life of FANUC CNC installations and legacy αi spindle systems.
