TOKYO -- October 29, 2012

Mitsubishi Electric Corporation (TOKYO:6503) announced today the launch of a
drive unit equipped with a silicon carbide (SiC) power module for computerized
numerical controllers (CNCs). The MDS-DM2-SPHV3-20080 is a multi-hybrid,
multi-axis integrated-drive unit for drive control of spindle and servo
motors. Sales will begin on December 3.

Power conversion modules are widely used in inverters and converters of
household appliances and industrial equipment. SiC power modules are superior
to conventional silicon (Si) modules in terms of their significantly reduced
switching loss and high tolerance to temperature.

To date, Mitsubishi Electric has commercialized SiC power modules for
inverters in air conditioners and railcars. The new SiC power module for CNC
drive units offers higher speed and torque for driving machine tool spindles
and servo motors, which is expected to improve manufacturing productivity in
factories.

Main Features

SiC power module for higher speed and torque

  *Power module uses diodes made with SiC
  *High-speed switching operation increases spindle motor speed up to twice
    that of its previous model (MDS-DM Series) under specific conditions.
  *Reduced power loss in drive unit results in 15% higher torque for spindle
    motors than MDS-DM Series under specific conditions.

Power shut-off and other functions enable downsizing and reduced wiring

  *The Safe Torque Off function for shutting off the power supply to motors,
    which reduces the number of magnetic reactors required, is available as a
    standard feature.
  *An interface for linear scale enables direct detection and feedback of
    machine positions, requiring no external interface unit.

Mitsubishi Electric's new CNC drive unit will be showcased at the 26th Japan
International Machine Tool Fair (JIMTOF 2012), which will be held at Tokyo Big
Sight in Japan from November 1–6.
