Technical specifications
Axis ratings, power architecture, interfaces and installation requirements for A06B-6240-H109.
Single-axis αiSV 360-B module
A06B-6240-H109 is the standard αiSV 360-B servo-axis amplifier for a FANUC αi-B 200 V-class drive system. It drives one servo motor and communicates with the CNC over FSSB. It is not a spindle amplifier, a mains power-supply module or an integrated servo/spindle unit.

Current rating by motor channel
| Parameter / condition | Rated current (Arms) | Nominal current limit (Apeak) |
|---|---|---|
| Single motor channel | 130 | 360 |
Rated RMS output current and peak current limit are different quantities. FANUC gives the nominal peak limit as a standard value with approximately ±10% circuit-constant variation; ambient temperature and HRV control mode govern output-current derating.
Model numbers are not continuous amperage
αiSV 360-B provides 130 Arms rated RMS output current. The 360 model-size figures identify the nominal peak current-limit class, not a continuous current rating. Motor selection uses the appropriate channel’s rated/peak requirements and the manufacturer motor/amplifier combination table.
The power supply feeds a shared DC link
In the 200 V-class system, three-phase 200–240 V AC enters the separately selected αiPS-B power supply. The αiSV-B receives the resulting DC-link power at TB1 and supplies controlled three-phase motor output. Do not connect the AC mains directly to the servo module’s DC-link terminals.

A FANUC servo-bus module, not an Ethernet drive
FSSB carries servo communication on optical cables. The applicable CNC families listed in B-65412EN/02 are 30i/31i/32i/35i-B, Power Motion i-A and 0i-D. The module is not specified here as an EtherCAT, PROFINET, analog-command or pulse-train standalone drive.
Original external-DBM connection diagram
B-65412EN/02, printed page 225. Use the αiSV 360-B case for this 200 V module; other HV models named in the shared original diagram are outside this PDP. One external DBM is required for each amplifier.
Isolate and discharge before servicing
Important fit check
The shared DC link can retain hazardous energy after the supply is removed. Do not touch the module or connected power cables while its DC-link charge indicator is lit. Isolate all relevant supplies and follow the manufacturer discharge and grounding procedure.
External dynamic brake module required
αiSV 360-B does not use the built-in dynamic-braking arrangement of the smaller modules. FANUC specifies one external DBM per amplifier. The standard options include A06B-6079-H401 with 200 V AC actuation or A06B-6079-H403 with 24 V DC actuation; select the module and its control wiring as a separate system component.

STO depends on the hardware edition
The manufacturer STO support table lists A06B-6240-H109 from Edition A onward, together with specified CNC servo-software requirements. JX8 and SW1 are the associated hardware interface and switch. An order code alone does not identify the installed hardware edition or configure a complete machine safety function. STO removes torque; it does not mechanically hold a vertical axis.
Keep the full module identity and channel layout
For a replacement, retain A06B-6240-H109, the αiSV 360-B axis configuration and the installed hardware/software edition. The single-axis current class and feedback arrangement are part of the configuration. Different H suffixes can change axis count, current capacity, SSM support or braking arrangements; similar yellow housings do not establish interchangeability.

Original module-outline comparison
B-65412EN/02, printed page 139, dimensions in millimetres. This model uses outline 4: 150 mm wide, with an external fin. Other outlines in the original comparison do not describe this product.
Original 200 V current-derating curves
B-65412EN/02, printed page 22. Select the curve for the actual HRV control mode; the 0–55 °C operating range is not a full-current guarantee throughout that range.
Reserve cooling and service space
Provide at least 50 mm of maintenance space above the module; FANUC recommends 80 mm for easier fan work. Keep airflow unobstructed and protect the radiator from coolant, oil mist and chips. Cable routing and maintenance space add to the module outline; do not size the cabinet from body dimensions alone.
