System compatibility:βiS series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with βiSV servo amplifier,used for CNC machine medium load feed axes.

Function:Permanent magnet AC servo motor for CNC feed axis. Realizes closed-loop position and speed control via built-in B128iA incremental encoder. Delivers stable medium torque output for feed motion. Keyed straight shaft for coupling connection.

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

Interface:

‑3-phase power connector

‑B128iA incremental encoder signal connector

‑Motor housing mounting flange

‑Keyed straight output shaft

Circuit feature:Built-in permanent magnet rotor,encoder signal sampling circuit,thermal temperature detection circuit.

Feature:FANUC βiS medium inertia servo motor,no brake design. Incremental encoder requires homing operation after power cycle. Common faults:encoder damage,coil burnout,shaft bearing wear,magnet demagnetization. Verify CNC controller and servo amplifier model before replacement.

Diagnostic:Motor or encoder failure triggers axis servo alarm,overload or position deviation alarm in CNC system.

Built‑in function

A06B-0062-B203 βiS4/4000 servo motor provides medium-torque high-speed precision closed-loop motion control for CNC machine feed axis. Widely used for CNC machine spare‑part replacement.

Product Brief

A06B-0062-B203 belongs to FANUC A06B servo motor spare parts family,0.75kW βiS4/4000 motor with keyed straight shaft and B128iA incremental encoder.
