What Is the A06B-0247-B000?
The A06B-0247-B000 is a FANUC AC Servo Motor belonging to the Alpha i F (AiF) series — FANUC’s high-performance servo motor family optimised for CNC machine tool axis drives requiring high torque output combined with precision positioning accuracy. The model designation AiF 22/3000 encodes the motor’s key performance parameters: 22 Nm stall torque and 3000 RPM rated speed. The -B000 suffix in FANUC’s A06B part numbering convention indicates a straight shaft (non-tapered) configuration, no electromagnetic brake, and the standard encoder specification. The motor operates at 4.0 kW continuous output power, 230 VAC 3-phase input (200–240 VAC range, 50/60 Hz), 8-pole configuration, at 200 Hz electrical frequency at rated speed. It carries IP65 ingress protection and Insulation Class F, making it suitable for the oil mist, coolant splash, and chip-contaminated environments typical of CNC machining centres and turning centres. The AiF series motors are designed to work with FANUC Alpha i series servo amplifiers (SVM — Servo Module) and are compatible with the full range of FANUC CNC controllers from Series 16i through to the current Series 30i/31i/32i and 0i-F platform. The A06B-0247 series (AiF 22/3000) is one of the most widely installed FANUC servo motor models globally, found in large vertical machining centres, gantry-type machining systems, and heavy-duty turning centres where high Z-axis and feed-axis torque is required.

AiF Series Applications and Amplifier Compatibility
The A06B-0247-B000 (AiF 22/3000) is optimised for high-torque feed axis applications in large CNC machine tools — typically the Z-axis (vertical) of large vertical machining centres, the X or Z axis of heavy-duty CNC lathes, and the main table axis of large horizontal machining centres where sustained high torque during heavy cutting operations is the primary requirement. The AiF designation (F = frame size) indicates a physically larger motor than the standard AiS series, providing higher torque output from the same rated speed. In the FANUC modular servo system, the A06B-0247-B000 is paired with a FANUC SVM (Servo Module) from the Alpha i series amplifier family — the appropriate SVM model is determined by the motor’s rated current and the CNC controller axis configuration. The motor is compatible with all FANUC CNC systems supporting Alpha i series servo: Series 16i, 18i, 21i, 30i, 31i, 32i, and 0i-D/F. The pulse coder interface uses FANUC’s high-speed serial encoder protocol (HSSB or FSSB depending on system generation), and the motor parameter (motor type number in FANUC parameter #2020) must be set correctly in the CNC controller to match the A06B-0247 motor characteristics.
Expert Tips
When the A06B-0247-B000 is installed as a replacement motor, always perform a servo parameter initialisation in the FANUC CNC after installation — set parameter #2020 (motor type number) to the correct value for the AiF 22/3000 as specified in the FANUC AC Servo Motor Descriptions manual (B-65262EN). An incorrect motor type number will cause the servo amplifier to use wrong current limits and gain settings, potentially resulting in servo oscillation, overheating, or immediate SV-alarm. Verify that the replacement motor’s encoder (pulse coder) is compatible with the amplifier’s interface: older AiF 22/3000 motors used the AiA 128 or AiA 64 pulse coder while newer revisions use the AiA 1000 — the pulse coder type determines the resolution available for positioning and must match the CNC parameter settings. After mechanical installation, check shaft runout with a dial indicator before connecting the motor coupling or ballscrew — FANUC AiF series motors have a shaft runout tolerance of 0.01 mm TIR, and excessive runout will cause premature bearing wear in the machine’s ballscrew coupling. If the motor has been in storage, rotate the shaft manually before powering up to redistribute the grease in the bearings — motors stored for more than 6 months may have partially dried bearing grease that can cause initial noise or vibration on first power-up.
Frequently Asked Questions
Q: What is the difference between A06B-0247-B000, B075, B100, and B705 variants?
A: All are AiF 22/3000 motors sharing the same electromagnetic specifications (22 Nm, 3000 RPM, 4kW). The suffix letters encode mechanical and options differences: B000 = straight shaft, no brake, standard encoder; B075 = tapered shaft (SLK), no brake; B100 = straight shaft, no brake, A1000 encoder variant; B705 = tapered shaft, 90V electromagnetic brake, 64ia encoder. Select the variant matching your machine’s shaft coupling type, brake requirement, and encoder compatibility.
Q: Which FANUC servo amplifier module (SVM) is compatible with the A06B-0247-B000?
A: The AiF 22/3000 motor (11 A continuous, 18 A stall) is typically paired with an SVM1-80 (A06B-6096-H105) or SVM1-130 (A06B-6096-H203) servo module depending on the drive configuration and whether it is a single-axis or multi-axis amplifier setup. Consult the FANUC Servo Amplifier Module Descriptions (B-65282EN) and your machine builder’s electrical drawings to confirm the correct SVM specification for your installation.
Q: What FANUC alarm indicates the A06B-0247-B000 motor encoder has failed?
A: Encoder failure on the A06B-0247-B000 typically generates SV-364 (APC: battery voltage zero — for absolute encoder), SV-365 (APC: battery low — encoder battery needs replacement), SV-366 (APC: pulse coder communication error), or SV-380 (excessive position error) depending on the nature of the failure. An intermittent SV-380 that occurs only during acceleration or deceleration often indicates a mechanical issue (coupling slip or ballscrew backlash) rather than an encoder fault.
