FANUC A06B-6220-H030#H600 — αiSP 30-B Spindle Amplifier Module

Part No.: A06B-6220-H030#H600 ▏Series: αiSP-B (200V Class) ▏Type: Spindle Amplifier Module ▏Condition: New Original ▏Also known as: AiSP-30 / SPM-30i

Overview

The A06B-6220-H030#H600 is a single-spindle amplifier module from FANUC's αiSP-B (Alpha i Spindle, B-generation) product line, designated internally as the αiSP 30-B. It occupies the mid-to-upper tier of FANUC's 200V-class spindle drive range, purpose-built to handle the continuous and peak torque demands of heavy-duty machining centres, turning centres, and compound multi-axis machines equipped with mid-range to large-frame FANUC α-series spindle motors.

Unlike standalone drive units, the αiSP-B operates within FANUC's shared DC-bus architecture. It draws regulated DC power directly from a companion αiPS-B power supply module (PSM), which manages AC-to-DC rectification and energy regeneration centrally. The amplifier module itself then handles all spindle-specific functions: current regulation, speed loop control, orientation, and C-axis positioning when configured accordingly.

The #H600 suffix confirms this is the 200V input class variant, distinguishing it from the 400V HV series (A06B-6221/A06B-6222 families). Physically the module consists of a power PCB and a dedicated control PCB contained in a single plug-in chassis, allowing field replacement of either board independently if required.

Technical Specifications

Compatible Spindle Motors

This module is matched to the following FANUC α-series spindle motors within the 200V class:

• αiIP 60/5000 — integral motor, 60 kW, 5,000 rpm continuous
• αiIT 15/15000 — through-spindle type, 15 kW, 15,000 rpm
• αiIT 15/15000 (Power Up model) — enhanced torque variant
• αiIL 8/20000 — in-line motor, 8 kW, 20,000 rpm
• αiIL 15/15000 — in-line motor, 15 kW, 15,000 rpm
• αiIL 26/15000 — in-line motor, 26 kW, 15,000 rpm

Motor selection must align with the amplifier's 148A peak output and the DC bus capacity of the installed PSM. Confirm motor cable and encoder cable routing follows FANUC's cabinet layout guidelines to avoid EMI-induced communication faults.

CNC System Compatibility

The αiSP 30-B communicates with the CNC via FANUC's FSSB (Fanuc Serial Servo Bus) fibre-optic link, making it compatible across the following control platforms:

• FANUC Series 30i / 30i-B
• FANUC Series 31i / 31i-B
• FANUC Series 32i / 32i-B
• FANUC Power Motion i-A (for robot and multi-axis motion applications)

Machines running the older 0i-D/F or 16i/18i/21i generations require a different amplifier family (A06B-6114 / A06B-6096 series) and are not compatible with this module.

Shared DC Bus Architecture

One of the defining characteristics of the αiSP-B series is the absence of an internal rectifier. All modules on the cabinet bus — servo axes and spindle — share a single DC rail supplied by the αiPS-B PSM. This arrangement reduces total cabinet component count and enables regenerative energy from decelerating axes to be redistributed across the bus in real time rather than dissipated as heat through braking resistors. When specifying a replacement PSM, verify that its continuous output rating covers the sum of all connected servo and spindle amplifier peak demands.

Alarm Reference (Common)

Fan alarms (AL-31 equivalent) are among the most common field faults; the internal fan A90L-0001-0581 and external fan A90L-0001-0577 should be inspected at scheduled maintenance intervals.

FAQ

Q1: What is the difference between A06B-6220-H030#H600 and A06B-6222-H030#H610?

Both are αiSP 30-B spindle amplifiers, but they belong to slightly different revision batches of the same 200V-class family. The A06B-6222 series represents a later production revision with minor PCB layout updates; the core electrical specifications — 283–339V DC input, 148A output — are identical. They are generally interchangeable within the same cabinet configuration, though FANUC recommends confirming parameter settings match the original unit before swapping.

Q2: Does this module include a built-in regenerative braking circuit?

No. The αiSP-B operates on a shared DC bus fed by the αiPS-B power supply module, which manages regeneration centrally for the entire amplifier stack. There is no separate braking resistor or chopper inside the A06B-6220-H030#H600 itself. If the bus voltage rises during rapid spindle deceleration, the PSM handles that energy — either returning it to the AC line or, on older PSM variants, diverting it to an external resistor.

Q3: Can this amplifier be used with a 400V three-phase mains supply?

Not directly. The A06B-6220-H030#H600 is the 200V class module; its DC bus input is specified at 283–339V DC, which is produced by a 200V-series αiPS-B power supply from a 200–240V AC three-phase mains. For 380–480V AC mains environments, the correct spindle amplifier family is the 400V HV series (e.g., A06B-6221 or A06B-6222 with #H610 or #H580 suffixes).

Q4: My machine is displaying spindle alarm C0 or C1 — does this indicate the amplifier has failed?

C0/C1/C2 alarms signal a communication error on the FSSB fibre-optic link between the CNC and the spindle amplifier, not necessarily a failed output stage. Before replacing the module, inspect the fibre-optic cables connecting the CNC to the SPM for physical damage, dust contamination on the connectors, or excessive bend radius. A loose or dirty optical connector is the most frequent cause of these alarms and can be resolved without hardware replacement.

Q5: What spare parts should be kept on hand alongside this amplifier module?

The two cooling fans are the highest-wear components: internal fan A90L-0001-0581 and external fan A90L-0001-0577. Both should be stocked as standard maintenance items, particularly in environments with elevated ambient temperatures or airborne particulates. In addition, having a spare FSSB fibre-optic cable set on hand allows rapid isolation of communication-related alarms during troubleshooting without waiting on parts procurement.
