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 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. 400V high voltage design reduces current loss for long cable installation. 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 βiS high voltage large inertia servo motor,no brake design. Absolute encoder eliminates homing operation after power restart. 400V high voltage version suitable for long cable transmission. 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 in CNC system.
