Use tomorrow’s technology today

small size big performer
Small size – big performer
  • Ultra-compact, cuts system component size
  • Supports space-saving gapless amplifier arrangement

= More flexible and cheaper installation

= Reduces switchgear cabinet size

168 mm


40 mm

a design that s up to any challenge
A design that’s upto any challenge
  • Plug & Play installation
  • USB port as standard

= Faster installation and setup

= Guaranteed performance utilisation

maximum torque minimum dimensions
Maximum torque –minimum dimensions
  • High torque capability, even at 6,000 rpm


  • Patented motor winding technology
  • Protected against dust and water jets


abs encoder for maximum precision

New HF series


ABS encoder formaximum precision
  • Smallest ABS encoder, developed by Mitsubishi
  • 262,144 steps per turn
  • Maximum speed constancy at low speeds
  • Axis limit switches can be eliminated
improved response


New HF series


Faster positioning

Improved response
  • Speed-frequency responseincreased to 900 Hz

= Faster positioning

= More accurate positioning

= Faster retooling

making the complex simple real time autotuning


Mass inertia ratio


Making the complex simple: Real-time autotuning
  • A single parameter to pre-calibrate the control circuit for the desired control level
  • Continuous and fully automatic adjustment of the controller


  • Ball screw, with a suspended load
  • 15% of Trated needed to overcome the friction coefficient
  • 55% of Trated for acceleration and deceleration
best performance guaranteed
Best performance guaranteed
  • Integrated machine analysis
  • Machine simulation for optimum systems
  • Extended filter frequency range (+4.5 kHz) to suppress mechanical resonances

= Maximum performance spectrum guaranteed – even for users without high-end experience!

Problems with structurally generated vibrations?

Vibration suppression delivers better quality!

software that makes your life easier
Software that makes your life easier
  • Comprehensive diagnostic functions
  • Oscilloscope function
  • Error memory
  • System setup
  • Machine analyser

= User-friendly configuration withMR-Configurator

sscnet iii the benchmark
SSCNET III – the benchmark
  • High Speed - 50 Mbit/s - Bus cycle time 0.44 ms
  • Up to 96 axes

= Fibre-optics connections for an interference-free bus

= Low cabling overheads

= Extended information

= Flexible solutions

the benefits an example
The benefits – an example

Complete installation and setup of a new machine with 3 highly-dynamic axes

Competitor: 60 man hours x €100

Mitsubishi MR-J3: 9 man hours= €5,100 saving

No external measurements required = €8,000 saving

No specialist required for servicing = €4,000 saving per event

Total saving €17,100

faster and more functionality
