Motors & Drives Information

VERNON HILLS, Ill. -- Mitsubishi Electric Automation Inc., a global supplier of automation products to all major industries, has introduced its F700 series of variable frequency drives (VFDs) that can control motors ranging from one to 800 horsepower. The F700 inverter features the latest version of Mitsubishi Electric's proprietary energy optimization software that boosts motor efficiency to new levels and maximizes energy savings.

"This new drive is suitable for virtually any general purpose application that involves a motor, whether it's on the shop floor, air-handling unit or machine room," said Chris Cusick, marketing manager for Mitsubishi Electric Automation. "The unprecedented range of the F700 makes it one of the most versatile VFDs on the market. Available for either 200V or 400V supplies, from 1-800HP, each VFD can control up to 4 pump or fan motors, resulting in significantly shorter payback times and reductions in maintenance costs in energy saving."

The F700 is a totally new design from Mitsubishi Electric, and features a new power module and hardware. Its NEMA 1 structure allows for safe, secure installations, whether in a panel or as a stand-alone module. Ease-of-programming is also a key benefit made possible by a jog dial that provides fast access to any of its 400 parameters. The F700 also incorporates an Optimum Excitation Control system that maximizes motor efficiency under all load conditions, and can even track and display energy and dollar savings in real time. Robust protective features help ensure that the drive will keep running despite fluctuations or interruptions in power.

The F700 VFD includes these new features:

--NEMA 1 enclosure designs: The drive can be mounted as a stand-alone unit where required.

--Ease-of-Programming: No more tedious scrolling to access parameters thanks to the new DU07 programming dial and FR-Configurator programming software.

--Windmill Start: The F700 measures residual motor slot ripple to determine both the rotation speed and direction of a coasting motor, and can swiftly and smoothly bring it under control when required, whichever way it's spinning.

--Enhanced Energy Savings: An improved version of Mitsubishi Electric's famous energy optimization software boosts motor efficiency by up to 12% over earlier generations, and intelligently maximizes energy savings.

--Energy Saving Signal: The F700 can calculate and display energy savings, either in dollars or kW/h.
