FANUC A06B-0374-B588 α2.5/3000 AC Servo Motor with αA1000 Pulse Coder

It is intended as a replacement for equipment originally fitted with the same complete FANUC motor number. Correct matching is important because motors within the A06B-0374 series may differ in shaft construction, feedback device, brake arrangement and environmental protection.

Verified α2.5/3000 Configuration

• Manufacturer: FANUC
• Part number: A06B-0374-B588
• Product type: AC servo motor
• Motor model: α2.5/3000
• Maximum speed designation: 3,000 min⁻¹
• Shaft: Straight, smooth shaft without keyway
• Feedback: αA1000 absolute pulse coder
• Feedback resolution: 1,000,000 divisions per revolution
• Brake: No holding brake indicated for the base B588 configuration

Actual machine performance depends on the matched FANUC servo amplifier, CNC parameters, mechanical load and installation conditions. The motor should be selected using the original machine specification rather than appearance alone.

αA1000 Absolute Feedback

The αA1000 pulse coder provides high-resolution absolute position feedback to the FANUC servo-control system. This feedback configuration must match the CNC, amplifier and existing motor requirements; it should not be substituted automatically with an incremental or differently rated pulse coder.

Absolute-position retention may depend on the machine’s backup-battery system. Before disconnecting or replacing the motor, follow the applicable FANUC maintenance procedure to reduce the risk of losing reference-position data.

Suffix and Replacement Identification

The unsuffixed A06B-0374-B588 is also listed in replacement markets as A06B-0374-B588#7000. Other modification suffixes may identify changes such as a keyed shaft, sealing treatment or approval specification. These versions should not be considered interchangeable unless the complete FANUC number and machine requirements have been checked.

Compatibility Check Before Ordering

Please compare the complete motor number on the original nameplate and verify the α2.5/3000 model, straight non-keyed shaft, αA1000 feedback, brake requirement, connectors and compatible servo amplifier. You can send REACO CNC a clear nameplate photo for identification assistance.
