Motor and Feedback Configuration

The A06B-0371-B075 converts commands from a compatible FANUC servo amplifier into controlled rotary movement for a machine axis. Its A64 absolute pulse coder supplies feedback used by the servo system to regulate position and speed.

FANUC motor-designation information identifies the B075 configuration as the Alpha 1/3000 motor with a taper shaft and A64 pulse coder. It should not be described as a straight-shaft, braked or incremental-pulse-coder motor.

Modification-Suffix Notice

The motor may carry an additional modification suffix, such as #7000, #7008 or another factory code, after A06B-0371-B075. This suffix can identify nameplate, approval, shaft-keyway or other production details.

Always compare the complete number printed on the motor nameplate. An A06B-0371-B075 with one modification suffix should not automatically be treated as identical to another suffix.

The A06B-0371-B075 is also different from nearby models such as A06B-0371-B077, A06B-0371-B575 and A06B-0371-B577. Similar motor frames do not confirm matching shaft, brake or feedback configurations.

Compatibility Check

Before ordering, please verify:

• Complete FANUC motor number and modification suffix
• Alpha 1/3000 motor designation
• Tapered shaft dimensions and keyway configuration
• A64 absolute pulse-coder requirement
• Motor power and feedback connectors
• Mounting flange and shaft coupling
• Servo-amplifier model and CNC parameters
• Machine-tool manufacturer’s original motor specification

Replacement and Support

This motor may be considered when troubleshooting pulse-coder alarms, unstable positioning, abnormal bearing noise, overheating, winding or insulation faults, damaged connectors, or physical shaft damage. The servo amplifier, feedback cable, power cable and machine mechanics should also be checked before motor replacement.

REACO CNC supplies tested FANUC servo motors with warranty support, testing-video service and worldwide express delivery. Please send a clear photo of the complete nameplate when requesting a quotation so the exact configuration can be confirmed.
