1 FA-EBG SERVO AND MOTIONS SYSTEMS

2 MARKET NEEDS High speed and high accuracy control for machines –Vibration suppression control at mechanical end –Ultra high speed position control More downsizing –Amplifier / motor downsizing –Less wiring Tuning set-up and maintenance ability have been improved –New auto-tuning functionaility –New maintenance functions

3 MELSERVO ROADMAP J2S – J2M J3 Increase productivity Maintenance free Down-sizing Overseas standards Network Intelligence diagnosis FMS High response Low noise Envelopment Low cost Reduce wiring High performance A SA - SB J H C J2 All digital Wire less Bus type axes control Pulse train General purpose Model Adaptive Control Real time Auto tuning Serial bus SSCNET 32-bit RISC CPU Notch filter Smallest size Amplifier Original Compact size Auto tuning ABS Encoder CE,UL Motor ID High density Machine analyzer SW Adaptive Oscillation Control Machine Simulation Gain Search Developed to MITSUBISHI original technology in advance of servo/motion field Vibration suppression control Linear AC servo motor 400V class Open networks High speed / torque High resolution encoder Advanced control Robust to external Force compensation Market MarketrequirementsFunctionality and andperformance

4 DEVELOPMENT CONCEPT Achieve to more capable performance easily for the machine and downsizing the component Competitor products Yaskawa – Sigma III Panasonic Minas - AIII High-level auto-tuning Advanced vibration suppression control High performance servo motor Evolutional configuration software Easy to use Maximum perfomance Machine performance Operation / tuning

5 POSITION OF MR-J3 50W3.5kW55kW7kW110kW J2-Super 750W J3 Performance and functionality

6 ULTRA-SMALL SERVO MOTOR Highest density coil by "joint-wrap" core method Smallest new development encoder IP65 The length (L) compared to HC series has been reduced by 23%The length (L) compared to HC series has been reduced by 23% Sizereduction Possible to change the cable direction - Either towards motor shaft or encoder Smallest in industry

7 LOW COGGING TORQUE SERVO MOTOR MORE STABLE MOTOR ROTATION HALF COGGING TORQUE HC MOTORHF MOTOR 750W MOTOR COGGING WAVEFORM

10 HIGH PERFORMANCE AMPLIFIER MR-J3-A Series

11 INCREASED SPEED RESPONSE Hz J2-Super J2 J3 0 200 400 600 800 1000 Achieve higher response Velocity speed-frequency 900Hz ! 19961998200020022004 Response (dB) -3dB Board chart

12 ADVANCED CONTROL VIBRATION SUPPRESSION CONTROL Tuning on Machine will vibrate with High gain setting High response Eliminate vibration High response Motor position In-position signal Machine position Suppress the mechanical vibration by auto-tuning

13 ADVANCED CONTROL ADAPTIVE FILTER II Suppresses vibration at high gain settings Frequency range increases – about 4.5kHz Auto-tuning ON Appling patent

14 ULTRA COMPACT SIZE AMPLIFER SMALLEST 70mm40mm 168mm 118cm 2 67cm 2 400W J2SJ3 40% size reduction

15 SET-UP CONFIGURATION SOFTWARE MR-CONFIGURATOR - MRZJW3-SETUP211E USB 1.1 Easy to set parameters Set-up support and diagnostics –Simple to tune Simple – easy to use auto-tuning –High level of tuning Graphic function – Graphic history function / Speed-Torque curve Machine Analyser II – Wide frequency range / more accurate –Diagnostics Amplifier diagnostics – External interface for self diagnostics

16 USB 1.1 INTERFACE USB 1.1 interface as standard –Fast response –Read time of graphic data : 20 times faster USB1.1 USB mini-B5 USB A Improve setting stage period

17 SIMPLE AUTO-TUNING SCREEN Suppress vibration auto-tuning Filter Auto-tuning 31 step response gain auto- tuning

18 GRAPHIC FUNCTIONS Command/Droop/Torque at same time monitoring 3 channel oscilloscope Settling/mechanical characteristics confirmation History function (Overwrite function) Sampling data : 0.4ms/30000points 12sec (J2S : 0.8ms/1024points)

19 MACHINE ANALYSER II More accurate mechanical characteristics Frequency range : 10Hz – 1kHz => 3Hz – 4.5kHz New algorithm More accurate J2-Super (151E software)J3 (211E software)
