Certification:CE
System compatibility:βiS series AC servo motor for FANUC 0iD / 0iMF CNC system,matched with βiSV servo amplifier,mainly used for CNC machine medium-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 B128iA incremental encoder. 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
‑B128iA incremental 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 βiS compact servo motor with holding brake,#0100 specification variant. Incremental encoder requires homing operation after power cycle. Brake only for static holding,not for dynamic braking. 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-0063-B503#0100 βiS4/4000 servo motor provides medium-torque high-speed precision closed-loop motion control and power-off holding function for CNC machine vertical feed axis. Widely used for CNC machine spare‑part replacement.
Product Brief
A06B-0063-B503#0100 belongs to FANUC A06B servo motor spare parts family,0.75kW βiS4/4000 motor with built-in holding brake,keyed straight shaft and B128iA incremental encoder,#0100 factory variant. Verify CNC system,servo amplifier and cable compatibility before ordering. Check winding insulation,encoder,bearing and brake function during commissioning. Widely applied for CNC equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
