Compact, Reduced Wiring and Easy MaintenanceHardware Configuration Featuring Advanced Technology
Very smooth rotation and quick accelerationAC SERVO MOTORS suitable for axis feed inmachine tools
• Compact sizeA new structure design makes the axial length ofthe motors shorter and contributes to downsizingthe m achines.
• Compact and super high-resolution α i seriesPulsecoderHigh resolution (standard: 1,000,000/rev., option16,000,000/rev.) and compact size, contribute tocompact and pr ecise machine.
• Intelligent Servo MotorThe α i Series Servo Motor features automaticidentification of the motor and pulsecoder to greatlyease the maintenance operations.
High-performance AC SPINDLE MOTOR withhigh power at high speed suitable forspindles in machine tools
• High power and high accelerationThe motors have constant power up to high speedand can be accelerated quickly. They feature anoptimum winding design and an effective coolingstructure.
• Coolant through Spindle Mot orCenter through coolant is possible through a direc
connection with spindle of the machining centerAir-cooled α Ti series and oil-cooled α Li series arealso available.
• Built-in Spindle Mot orWhen high speed, high accuracy, and low vibrationneed to be achieved with simple mechanicastructure.
Compact and energy-saving Servo Amplifier
• Compact sizeWidth is reduced by 20% (average) and depth is
reduced by 11% compared to previous m odel.
• Energy-savingPower loss is reduced by 10% using the latest IPMtechnology.
• Smart maintenanceSmart maintenance is possible using ID and motorthermal information.

High-speed and high-precision servo controlThe combination of "Smooth command by Nano Interpolation"
and "High gain servo system" (SERVO HRV Control), allows
high-speed and high-precision control at the nano-meter level.
SERVO HRV Control
SPINDLE HRV Control
Quick acceleration and high response(SPINDLE HRV Control)Quick response and high stability of current control has beenenhanced with high-speed DSP and advanced controalgor ithm (SPINDLE HRV Cont rol ).
High-response and high-precision spindle control is realizedwith faster velocity loop sampling time and a high-resolutiondetector circuit.
Contro l of C-axis contouri ng is now easier than ever.
Ultrasmooth rotationUltrasmooth servo feed is ensuredby combining "Servo motor withultrasmooth rotation", "Accuratecurrent detection", "High-responseand high-resolution Pulsecoder",and "High-speed and high-precisionservo control".

High Speed, High Precision and High EfficiencyState-of-the-Art Servo Control Technology
Energy-SavingFANUC has prom oted energy-saving of the servo system w ithdirect energy consumption reduction:
- improving the efficiency of the servo system
- indirect energy consumption reduction by shortening thecycle tim e with h igh speed and high-acceleration control.
αi series is a further advanced energy-saving servo system,successor of t he α series which won the 1999 MITI Award forEnergy Saving Equipment.
Conformity to Safety Standards (EN, UL/CSA)Motors and amplifier modules meet UL/CSA standard forNorth America, and Safety/EMC standards required tocomply with CE Marking of machines shipped to theEuropean market.
Servo Tuning Tool
Quick & easy tuning for Servo and SpindleThis software provides the integrated environment to testprograms, set parameters and measure data, needed forservo and spindle tuning.
Direct connection is possible betweenthe PC and the CNC through a PCMCIA-LAN card, attached on the CNC frontpanel.
