System compatibility:βiS HV high voltage series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with βiSV-HV 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. 400V high voltage design reduces current for long cable applications. 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 high voltage compact servo motor,no brake design. Incremental encoder requires homing operation after power cycle. 400V high voltage version suitable for long cable transmission. 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.
