FANUC A06B-0114-B503 Servo Motor

Technical Specifications

Model:A06B-0114-B503

Brand:FANUC

Series:αiS15/2000

Rated power:1.5kW

Rated speed:2000rpm

Voltage:3-phase 200~240VAC

Encoder:BiA128 absolute encoder

Shaft:straight shaft with keyway

Brake:Built-in 24VDC electromagnetic holding brake

Insulation class:F

Protection class:IP67

Weight:13kg

Dimensions:100mm ×100mm ×265mm

Certification:CE

System compatibility:αiS series servo motor for FANUC 0iD / 0iMF CNC system,matched with αiSV servo amplifier,for CNC vertical feed axes.

Function:Permanent magnet AC servo motor for CNC feed axis. It realizes closed-loop position and speed control via built-in BiA128 absolute encoder. Absolute encoder saves position data after power off,no homing required. Built-in brake locks shaft to prevent load dropping during power failure.

Installation:Flange mount,connect power cable,encoder cable and brake control cable to servo amplifier.

Interface:

‑3-phase power connector

‑BiA128 absolute encoder signal connector

‑24VDC brake power terminal

‑Motor housing mounting flange

‑Keyed straight output shaft

Circuit feature:Built-in permanent magnet rotor,encoder sampling circuit,temperature detection circuit,brake coil drive circuit.

Feature:FANUC αiS low inertia servo motor,with holding brake. Absolute encoder removes homing operation after power restart. Keyed shaft design. Common faults:encoder damage,coil burnout,bearing wear,brake pad aging. Confirm full model for compatibility before replacement.

Diagnostic:Motor or encoder damage will trigger servo alarm,overload or position deviation alarm on CNC system. Brake failure may cause vertical axis drop risk.

Built‑in function

A06B-0114-B503 αiS15/2000 servo motor provides stable high-precision closed-loop motion control and power-off holding function for CNC vertical feed axis,widely used for CNC spare part replacement.

Product Brief

A06B-0114-B503 belongs to FANUC A06B servo motor spare parts family,1.5kW αiS15/2000 motor with keyed shaft,BiA128 absolute encoder and holding brake. Verify CNC system,servo amplifier and cable compatibility before ordering. Check winding insulation,encoder,bearing and brake function during commissioning.
