AC Servo legacy products

MPAC Ltd. Can support and supply parts for legacy products up to and beyond end of life.

Protecting your investment in Mitsubishi Electric products is one of our top priorities. Time and time again we have helped our customers to enable their investment to migrate and transition forward into newer, more advanced offerings. The average lifecycle of a Mitsubishi Electric automation product can be 10 years or more.

Although we have experience with Mitsubishi products operating reliably for periods in excess of 30 years. Mitsubishi offer innovative and technologically advanced products for industrial automation which are constantly evolving, so after a number of years a newer version of a product will be launched, the older version will remain available for a period of time then spares will remain available for a further period of time. Eventually spares parts will no longer be available and the best option for companies is to migrate to the newer platform while the installed system is still operable.

Product end of life is always carried out in a structured manner and a great deal of effort is made on the part of Mitsubishi to accommodate legacy versions of a product when a new model is launched.
Please feel free to contact us for further details of upcoming discontinuations, product availability, service, repair, and transition options.
Our goal is to help you determine the best way to introduce new technology, while reusing as much of your existing investment as possible.
We can also assist in upgrading legacy or obsolete equipment from other manufacturers and offer a migration solution. Please contact MPAC to discuss available migration options.


mitsubishi-mr-jMitsubishi MR-J:

Background: Launched more than 25 years ago, the MR-J series is Mitsubishi Electric’s flagship family of high-performance servo systems.

Lifecycle: Introduced (1988) – Discontinued (2000)

Service Life: Repair Service was made available through November 2008.

Migration Info: Customer still using the MR-J amplifiers and MR-J motors should migrate to the new MR-J4 servo amplifier and HG servo motor product lines. For further information, please contact MPAC to discuss available migration options.


mitsubishi-mr-hMitsubishi MR-H:

Background: The MR-H (AN/BN) product line served as a high performance single axis amplifier with a high-performance 32-bit RISC processor and a 200Hz frequency response. This amplifier was used in applications requiring short settling times and high precision. The MR-H Servo Amplifier was with employed multiple industry leading technologies and was ideal for applications a wide variety of applications including rotary tables, roll feeders, inserters (x-y table), machining tools, conveyors requiring highly stable control.

Lifecycle: Introduced (1993) – Discontinued (2005)

Service Life: Repair service for MR-H products was available until 11/2012.

Migration Info: The MR-J4 amplifier and HG motor series integrate seamlessly with your existing manufacturing assets, ensuring a smooth transition to the speed and cost benefits of leading-edge technology. For further information, please contact MPAC to discuss available migration options.
