A06B-0114-B075#0008 Fanuc AC Servo Motor A06B0114B075#0008 AO6B-OII4-BO75#OOO8 A06B-0114-B075/0008

FANUC A06B-0114-B075#0008 | BM0.4/4000 AC Servo Motor — #0008 Option Variant

Part Number: A06B-0114-B075#0008

Base Part Number: A06B-0114-B075

Manufacturer: FANUC Corporation (Japan) 

The #0008 Suffix in Context

The A06B-0114-B075#0008 is the BM0.4/4000 servo motor in the #0008 option configuration. In FANUC's motor ordering system, the four-digit suffix after the # symbol encodes the specific combination of shaft type, brake option, and encoder configuration for that unit. The #0008 designation identifies this as a specific factory configuration within the A06B-0114-B075 base motor series.

Mechanically and electrically, the motor shares the same core specifications as the A06B-0114-B075 base: 0.4 Nm rated torque, 4,000 rpm, BA64B incremental encoder, and a straight shaft with machined keyway. The suffix specifies the exact combination of options as built — relevant when verifying the correct replacement for a specific machine installation, because the shaft, encoder, and brake configuration must match the original to ensure compatibility with the mechanical coupling, the servo drive interface, and the machine's safety system.

When ordering a replacement, the full part number including the suffix — A06B-0114-B075#0008 — is the definitive ordering reference. The base part number without suffix may include multiple configuration variants; only the complete number with suffix guarantees the correct combination.

Key Specifications

FAQ

Q1: What does the #0008 suffix mean on the A06B-0114-B075?

FANUC uses the 4-digit suffix after # to encode the specific factory configuration of shaft type, brake, and encoder options. #0008 identifies a specific combination of these options for this motor. When sourcing a replacement, provide the full part number including #0008 to ensure the correct configuration is supplied.

Q2: Can A06B-0114-B075 (no suffix) substitute for A06B-0114-B075#0008?

The base number and the suffix together define the motor's complete specification. A unit without the #0008 suffix may differ in shaft configuration, brake provision, or encoder type. Before accepting a substitution, confirm the physical shaft dimensions, brake wiring (if applicable), and encoder compatibility with the installed servo drive all match.

Q3: The encoder alarm has appeared. How is it confirmed as an encoder fault vs a cable fault?

Remove the encoder cable at both ends and inspect connectors for corrosion, bent pins, or damaged insulation. Reseat firmly and test. If the alarm clears, the connector was the fault. If it persists with confirmed-good connector and cable, the encoder on the motor has failed. Replace the encoder or the complete motor depending on availability.

Q4: After replacing the motor with a new A06B-0114-B075#0008, the axis shows position drift at rest. What should be checked?

Position drift at rest after motor replacement typically points to encoder calibration or feedback parameter settings. Verify the servo drive's feedback scaling parameters match the BA64B encoder's specification. Also check that the encoder cable shield is properly grounded at the drive end — ungrounded shields pick up noise that produces apparent drift at low speeds.

Q5: Is A06B-0114-B075#0008 available new or only as a used part?

BM series motors are discontinued by FANUC and are available primarily through the CNC parts aftermarket — tested surplus units and refurbished motors from specialist repair companies. Confirm the suffix #0008 is present on the supplied unit's nameplate before accepting delivery.
