The FR-F700 offers a range of
features that benefit most motor applications. These features
also make the FR-F700 ideal for
fan and pump applications.
Freewheeling occurs when external pressures turn a nonpowered
motor in either direction, for
example static head pressure
forces a pump to rotate. Starting
a motor in this state could cause
a motor to trip under an overload
condition. The FR-F700 virtually
eliminates this problem.
When the FR-F700 is started it can
automatically sense direction and
speed of the motor, bringing it
under control immediately - often
called a flying start.
With an automatic restart after a
brief power outage, the Inverter
automatically "catches" the
motor while it is coasting and
accelerates it to its preset speed
providing immediate recovery
and minimal loss of control.
Sometimes a powered motor
can be overdriven by its load,
the motor then acts as a generator and can create high voltages within the drive. The
FR-F700 can increase its output
frequency to avoid tripping.
Optimum motor protection
can be achieved by connecting
the motor's PTC temperature
sensor to the drive's temperature monitoring system.
The FR-F700 can automatically
operate up to four load-controlled motors from a single
inverter. As each motor is
brought up to speed it is then
switched 'direct on line' allowing the next motor to be controlled. Slowing, is a reverse of
the same process.
The FR-F700 easily handles
HVAC applications that require
local PID control or can act as
part of a larger building
network such as LON Works.

Optimum
Excitation
Control
The FR-F700 can achieve
particularly impressive power
savings in the low speed range
and during the acceleration
and braking phases. For
example, at a frequency of
35Hz it uses 57% less power
than conventional solutions.
And the pioneering OEC
(Optimum Excitation Control)
function cuts consumption by
another 10%. OEC ensures that
the motor always gets the
optimum magnetic flux, for
maximum motor effectiveness
and efficiency.
A combination of many intelligent
design features and newly developed components (including
the fans and capacitors) have
increased the service life of the
FR-F700 to over 10 years. An
automatic warning is displayed
when the end of the service life
is approaching, so that you can
avoid unexpected failures.
Setup is fast and maintenance is
simple, thanks to preconfigured
parameters, fast and easy
parameter configuration and
easy replacement of components like fans and terminal
blocks when necessary.
Assuming an application with
a 75 kW motors, an electricity
price of 0.14 per kWh, the
cost calculations are as follows:
Conventional mechanical solution
Air volume 60%, power consumption 90%*:
75kW x 0.9 x 0.14 x 24h x 365 days = 82,782
FR-F700 frequency inverter solution
Air volume 60%, power consumption 33%*:
75kW x 0.33 x 0.14 x 24h x 365 days = 30,353
Result:
This means that FR-F700 generates
Savings of 52,429 per year!

The power savings
achieved can be
displayed on the control
unit in a number of
different ways:
● Current value in kWh,
% or money units
● Average value in kWh,
% or money units
● Annual value kWh or
money units
The integrated one-touch
Digital Dial gives you much
faster access to all the
important parameters than
would be possible using
conventional control keys.
The removable FR-DU07
control unit makes operating
the inverter simple and
intuitive. A 4-digit LED display
enables you to check and edit
settings, and it is also used for
monitoring operating status
and displaying alarms. You
can monitor all inverter and

The frequency inverters of the
FR-F700 series are available
with outputs from 0.75 to
630kW. They are specially
designed for the needs of
pump and fan applications
but they are also an excellent
choice for standard
applications with a maximum
overload of 150%. All units in
the series are configured for
connection to 3-phase 380 to
480/500V (50/60Hz) mains
power supplies.
The output frequency range is
from 0.5 to 400Hz.

Clean water, pleasant air temperatures and ideal humidity at all
times, despite constantly-changing environmental conditions:
In pump and fan applications
for swimming pools you need
variable-speed drive systems
that are able to respond with
great flexibility, like the FR-F700
with its intelligent motor control
functions. The greatest power
savings are achieved when the
pumps and fans are running
under partial load - for example,
if the motor can be operated at
half speed it only consumes one
eighth of the energy required for
full speed operation!
The ventilation systems used
in spray-painting plants often
need very powerful motors.
The intelligent motor control
functions of the FR-F700
reduce the start-up currents
and thus also the peak load
power costs. These inverters
also significantly reduce
power costs in low-load
operation, and their ability to
perform gentle flying starts
for motors already rotating in
duct drafts also increases the
system's service life.
Water utility companies must
be able to respond quickly
and flexibly to sudden
increases in demand, for
example in the early morning
hours. With its multi-motor
function a single FR-F700 can
integrate up to 4 motors in a
single pump system. One
motor at time is frequencycontrolled by the FR-F700
while the others are
successively connected to or
disconnected from the mains
power. That is effective motor
management.
