Introducing
Mitsubishi's New A700 Family
of Drives
The
A700 is a high performance version of Mitsubishi Electric's F700
variable frequency drive,
which will replace the popular A500(L) series. The VFD
features
many
of the special technologies originally developed for Mitsubishi
Electric servo drive products, such as adaptive auto tuning that
automatically compensates for changes in load inertia. The
result
is smoother operation, less downtime and ultimately, lower operating
costs.

Able to control
½-600 hp motors, A700 uses adaptive auto tuning to
compensate for changes in load inertia. Encoder feedback enables unit
to operate in flux-vector mode to generate torque at zero speed while
also allowing positioning control. With speed response time of 300
radians/sec, drive may be used without encoder and can control torque
as well as speed. Product uses Real Sensorless Vector (RSV)
Algorithm to provide 200:1 speed range.

Mitsubishi Electric Automation Introduces Its Newest VFD, the
A700
Intelligent Drive Controls Motors from 1/2 to 600
Horsepower.
Vernon Hills, Ill.-September 6, 2005-Mitsubishi Electric
Automation, Inc., a global supplier of automation products to all major
industries, has introduced its A700 high performance variable frequency
drive (VFD) for controlling motors ranging from 1/2 to 600 horsepower.
It will replace the company's highly successful A500 and A500L drives,
which have been available since 1997.
The A700 is the first drive from Mitsubishi to feature a built-in
programmable logic controller (PLC) and features many of the special
technologies originally developed for Mitsubishi Electric servo drive
products, such as adaptive auto-tuning which automatically compensates
for changes in load inertia. The result is smoother operation, less
downtime and ultimately, lower operating costs.
"The A700 is faster, smarter and more powerful than any standard VFD
we've ever produced," said Chris Cusick, marketing manager for
Mitsubishi Electric Automation. "And with its built-in programmable
logic controller, users can customize the drive to their unique
application."
Exceptionally versatile, the A700 achieves class-leading motor
performance using encoder feedback to operate in "flux-vector" mode to
generate torque at zero speed and allowing positioning control. With a
speed response time of 300 radians per second-10 times faster than the
A500-the A700 reacts quickly to sudden load changes with utmost
efficiency.
Used without an encoder, the A700 uses the newly developed "Real
Sensorless Vector" (RSV) algorithm to provide a 200:1 speed range. Its
ability to control torque as well as speed makes it ideal for
applications where constant tension must be maintained, such as
wind/unwind control.
Communications to the A700 are supported with most popular protocols,
including Profibus DP, CC-Link, DeviceNET, LonWorks, ControlNET, Modbus
RTU, Metasys N2, EtherNET IP and Modbus TCP/IP, as well as Mitsubishi
Electric's proprietary RS485 network. In addition, SSC Net III,
Mitsubishi's high performance, fiber-optic motion network is also
supported, allowing the A700 to operate in conjunction with Mitsubishi
Electric's new J3 servo drives and complete line of motion control
products.
