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