series is optimised for the special needs of
fan and pump applications. Drives in appli
cations like these are characterised by a
load torque curve that increases by the
square of the motor speed (variable curve).
Of course, these frequency inverters can
also be used for standard applications with
constant load curves and a maximum over
load of 150%.

Intelligent Technology that Cuts Power Consumption

SYSTEM DESCRIPTION

Saving power with Mitsubishi
frequency converters

Reducing consumption and optimising the
utilisation of our valuable energy resources
is one of the greatest global environmental
challenges of our age.

Energy conservation mode is a standard
feature of the intelligent controller. It dyna
mically adjusts the voltage to motor requi
rements, eliminating unnecessary power
losses, which helps to further reduce po
wer consumption. Frequency inverters are
particularly effective at conserving energy
when they are used to control pumps and
fans.

Theamountofenergyconservation(hyste
resis) depends on the speed/torque fluc
tuations. The graph below provides an im
pressive example of the results of
intelligent control in a fan system.

How do frequency inverters
conserve energy?

The illustration below shows a blower sys
tem in which the air flow is regulated by
controlling the motor with a frequency in
verter instead of with a damper on the ex
haust side.

The graph below compares the motor po

­wer consumption of the frequency inverter

­and damper solutions. At a flow rate of
60% the curve shows that the frequency
inverter system consumes a full 60% less
power than the motor with the damper
system.

Potential savings

In addition to the ecological benefits fre
quency inverters can also save a great deal

­of money by radically cutting power con

sumption.

-

-

Example:
Based on the graph on the left and an elec

-

tricity price of 14 cents per kWh, the follo
wing savings can be achieved with a sys
tem using a 75 kW motor:

Conventional mechanical solution

앬

At an air throughput of 60% the power
consumption is 90%, resulting in the
following annual costs:

75 kW x 0.9 x €0.14 x 24 h x 365 days
= €82,782

Frequency inverter solution

앬

At an air throughput of 60% the power
consumption is 30%, resulting in the
following annual costs:

75 kW x 0.3 x €0.14 x 24 h x 365 days
= €27,594

This means that the inverter solution saves
€55,188 per year compared to the conven­tional mechanical system!

Clearly, a frequency inverter will pay for
itself in a very short time – and one must
also remember that the potential savings
increase with the power ratings of the
motors used.

Energy savings control

The effect of energy savings can be confir­med using the control panel, via the
output terminals (CA, AM) and via net
works (network option required) with the
newly developed energy saving monitor.

SYSTEM DESCRIPTION

Intelligent Motor Control Functions

Extended PID control

The FR-F 740 series supports extended PID
control. This feature makes it possible to
connect the process status signal to the fre
quency inverter as a voltage signal
(0–10 V DC) or a current signal
(0/4–20 mA DC) and then use the analog
input calibration function of the inverter to
compensate minor controller-related fluc
tuations.

In addition to this the frequency inverter
can also control up to four motors succes
sively. This function is programmable; for
example, you can program it so that only
one motor is frequency-controlled and the
others are switched on and off under direct
mains power as required, or you can alter
nate between direct mains power and
frequency control for all four motors.

The graph on the right illustrates this multi­motor switching function with a typical ex
ample.

When implementing an application like
this you must plan the necessary number
of magnetic power contactors and the re­quired number of output signal terminals
on the inverter. Care must also be taken to
ensure that the mains power is never swit­ched to the inverter output.

Flexible 5-point V/f curve

The integrated flexible 5-point V/f curve
enables you to match the torque curve
perfectly to the characteristics of your
machine.

Together, the optimum excitation control
feature and the 5-point V/f curve achieve
significantly increased power savings.

Automatic restart after instantane
ous power failures

In pump and fan applications normal ope
ration can be continued automatically af
ter brief power failures. The system simply
reactivates the coasting motor and auto
matically accelerates it back up to its
setpoint speed.

The graphic on the right shows how the
frequency inverter can respond to a brief
power outage. Instead of coasting down
completely and stopping, the motor is au
tomatically “caught” by the frequency in
verter and re-accelerated back up to its
previous speed.

Innovative Features and Functions

SYSTEM DESCRIPTION

Flying start

Gentle restart of a rotating motor (e.g. fan
rotated by a draft), also in the opposite di
rection.

PTC temperature sensor input

The motor’s internal PTC temperature sen
sor can be connected to the inverter di

­rectly. In combination with the electronic
temperature monitoring system this provi
des effective protection for the motor.

Active current limiting

Tried and tested capabilities like the active
current limiting feature have been retai
ned. The characteristics of the current limi
ter have now been further improved to
prevent unwanted triggering in response
to overcurrents. Transient overcurrents, for
example those generated when a motor
coasting in reverse is restarted or when an
input contactor is closed, will no longer
cause unwanted triggering of the current
limiter.

-

Magnetic flux vector control

The integrated motor flux vector control
system makes it possible to achieve high

­torques, even at low motor speeds.

Optimum excitation control

You can also select the optimum excitation

­control mode, which achieves yet more
power savings compared to conventional
inverters designed for pump and fan appli

­cations.

The graph below demonstrates the kind of
improvements that are possible with this
control mode:

Regeneration avoidance function

This function can prevent the inverter from
being shut down by regenerative overvol
tages when strong regenerative loads cau
se power to be released into the frequency
inverter (for example when braking the
motor or with loads that actively drive the
motor).

The inverter can automatically increase the
output frequency or disable the braking

-

ramp when a programmed threshold value
is reached. The response sensitivity, dyna
mics and working range are all adjustable.

For example, this function can prevent a
shutdownwithanovervoltageerrorwhen
the speed of a fan controlled by the inver
ter is increased by the draft from another
fan operating in the same ventilation duct.
The function then temporarily increases
the output frequency above the setpoint
value.

This function can also be used to brake lo
ads with the DC bus voltage, without using
braking modules.

Switching to direct mains operation

You can switch the motor to direct mains
operation by programming the contactor
relays accordingly and applying a control
signal to terminals L11 and L21 of the
inverter.

-

Traverse function

The traverse function of the FR-F740 is de
signed specifically for use in yarn-winding
applications in the textile industry.

This function performs a cyclical variation
of the output frequency as shown in the
graph on the right. The width of the fluc

­tuation around the frequency setpoint va
lue and the ramp times are configurable
via setup parameters.

This function prevents the formation of the
unwanted “bands” in the wound yarn.

User-friendly Operation

Easy configuration with control
panel or software

The FR-DU07 control panel is included as
standard equipment with all the inverters
of this series. It makes operation of the in
verter simple and intuitive and displays
operating parameters and alarm messa
ges. The jog shuttle “digital dial” control
provides fast and efficient access to all key
drive parameters.

The optional FR-PU04 control panel featu
res a long-life LC-display with a backlight
and integrated numeric keypad for direct
entry of operating parameters. The user
interface can be displayed in eight diffe
rent languages. This panel is designed as a
remote unit that is connected to the inver
ter with a cable. It also supports definition
of user groups with which you can imple
ment editable parameter sets that can
then be selected as required for specific
applications.

User-friendly

In addition to allowing you to enter and
display configuration and control parame
ters the integrated control panel can also
be used to monitor and display current
operating data and alarm messages. The
information is output on a 4-digit LED dis
play.

You can monitor all the current status pa
rameters of both the inverter itself and the
connected motor. Problems and mal

functions are indicated by error codes.

One-touch operation

Simple and intuitive configuration and
operation save both time and money. The
control panel’s jog shuttle “digital dial”
control provides much faster access to all
key drive parameters than would be possi
ble with conventional buttons and keys.

You can also use the dial to continuously
adjust the speed of the connected motor.

Long Service Life and Easy Maintenance

SYSTEM DESCRIPTION

New components for longer service
life

The components of this new generation of
frequency inverters are specified for a ser
vice life of 10 years (mean annual ambient
temperature 40°C, 80% load in an environ
ment free of aggressive gases, flammable
gases, oil mist, dust and dirt). Among other
things,thisismadepossiblebythe
newly-developed, long-life cooling fans
that are monitored by the inverter. The life
of the cooling fans can also be made signi
ficantly longer by using Parameter 244,
which controls the selective shutdown
feature.

Modern diagnostics functions furt

-

her extend service life

The ageing of the main circuit capacitors,
the control circuit power capacitor, the in
ternal cooling fans and the inrush current
limiter circuit can be checked with the mo
nitoring functions. If the inrush resistor
overheats an alarm is displayed.

The alarms for the main circuit capacitors,
control circuit capacitor, inrush current li­miter and internal fans can all be output to
a network or via the optional FR-A7AY
module.

This makes it possible to prevent mal­functions by configuring diagnostics
alarms to be triggered when the end of the
service life is reached.

The inverter also has an internal program
that can evaluate the ageing of the main
circuit capacitors. This feature is only avai
lable when a motor is connected to the
inverter.

Easy replacement

The terminal block for the control circuit
connections is removable to enable easy
replacement of the inverter unit for servi

­cing, which greatly facilitates both installa

tion and maintenance work. You can also

­use the removable terminal block of the

FR-F500 series, which is compatible to the
FR-F700 series. However, please note that
some of the functions of the FR-F700 series
are not available when you use a terminal
block from the FR-F500 series.

Service timer

The frequency inverters of this series all
have an integrated service timer that auto
matically triggers an alarm after a set num
ber of operating hours. This feature can be
used for monitoring the frequency inverter
itself or a peripheral component. The valu
es of the mean output current and the ser
vice timer can also be output as analog
signals.

Improved handling

The main cooling fan is easily accessible at
the top of the inverter unit, allowing quick
and easy replacement without removal of
the connection cables.

The cable guide comb (see illustration) is
removable and makes routing the cables
quick and trouble-free. After the cables
have been connected the cover can then
be replaced (for frequency inverters up to
type 00620).
