Insulation class:F

Protection class:IP67

Weight:25.5kg

Dimensions:140mm ×140mm ×320mm

Certification:CE

System compatibility:αiS series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with αiSV servo amplifier,used for CNC machine heavy-load vertical feed axes. #0100 represents factory specification variant.

Function:Permanent magnet AC servo motor for CNC feed axis. Realizes closed-loop position and speed control via built-in BiA128 absolute encoder. Absolute encoder retains position data after power cycle, no homing required. Integrated electromagnetic holding brake locks shaft upon power loss to prevent vertical axis sliding. Keyed straight shaft for coupling connection.

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 signal sampling circuit,thermal temperature detection circuit,brake coil drive circuit.

Feature:FANUC αiS medium inertia servo motor with holding brake,#0100 specification variant. Absolute encoder eliminates homing operation after power restart. Brake only for static holding,not for dynamic braking. Keyed straight shaft for convenient assembly. Common faults:encoder damage,coil burnout,bearing wear,brake pad aging. Use full part number including #0100 suffix for compatibility confirmation before replacement.

Diagnostic:Motor or encoder failure triggers axis servo alarm,overload or position deviation alarm;brake malfunction leads to vertical axis drop or brake release alarm.

Built‑in function

A06B-0085-B503#0100 αiS22/2000 servo motor provides high-torque stable precision closed-loop motion control and power-off holding function for heavy load CNC machine vertical feed axis. Widely used for CNC machine spare‑part replacement.

Product Brief

A06B-0085-B503#0100 belongs to FANUC A06B servo motor spare parts family,2.5kW αiS22/2000 motor with built-in holding brake,keyed straight shaft and BiA128 absolute encoder,#0100 factory variant.
