FANUC A06B-0314-B041 Model 5S AC Servo Motor with 2000P Absolute Pulse Coder

This motor should be selected as a replacement using the complete FANUC number and original nameplate data. Similar A06B-0314 motors can have different feedback devices, shafts, brakes and modification suffixes even when their housings appear identical.

Verified Model 5S Nameplate Data

• Manufacturer: FANUC
• Part number: A06B-0314-B041
• Motor series: FANUC S Series
• Motor model: 5S
• Maximum speed: 2,000 min⁻¹
• Stall torque: 5.9 N·m
• Stall current: 5.8 A
• Motor voltage: 126 V
• Electrical configuration: Three phase, eight poles
• Shaft: Tapered; keyway configuration must be checked by suffix
• Feedback: 2,000P absolute pulse coder
• Brake: No holding brake

The 126 V value is motor-side nameplate data and is not an instruction for direct connection to an AC power supply. The motor requires a compatible FANUC servo amplifier, the correct feedback interface and machine-specific CNC parameters.

2000P Absolute Position Feedback

The absolute pulse coder returns rotor-position and speed information to the FANUC servo-control system. The replacement motor must retain the required absolute-feedback type; a 2,000P incremental encoder or another pulse-coder resolution should not be treated as an automatic substitute.

Absolute-position retention may depend on the CNC or servo-system backup battery. Before removing the original motor, check battery condition and follow the applicable FANUC encoder-disconnection and reference-position procedure.

Tapered Shaft and Modification Suffix

The base part number is also commonly indexed as A06B-0314-B041#7000. Complete suffix versions may change whether the tapered shaft has a keyway and whether standard or special sealing is fitted. Keyed, non-keyed and waterproof versions should not be interchanged without checking the complete nameplate number.

Replacement Compatibility Check

Before ordering, verify the complete FANUC part number, Model 5S requirement, 2,000 rpm speed, tapered shaft and keyway, 2,000P absolute pulse coder, no-brake configuration, power and feedback connectors, servo amplifier model and CNC parameters. Send REACO CNC clear photos of the motor nameplate, shaft and connectors if identification assistance is required.
