System compatibility:αiS HV high voltage series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with αiSV-HV servo amplifier,used for CNC machine heavy load feed axes.

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. Keyed straight shaft for coupling connection.

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

Interface:

‑3-phase power connector

‑BiA128 absolute 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 αiS medium inertia high voltage servo motor,no brake design. Absolute encoder eliminates homing operation after power restart. Keyed straight shaft for convenient assembly. 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.
