The new FR-F 700frequency inverter hasenormous potential forpower savings and isparticularly well suitedfor pumps, fans and allapplications withreduced overloads,including:

● Air conditioningsystems in buildingmanagement andindustry

● Air extraction andventilation systems

● Hydraulics systemsand compressors

● Sewage systems,ground water pumpsand heat pumps

● Drives with a highpercentage of idlingoperation

● Spinning and knittingmachines and looms

● Machine tools

● Conveyor belts andworm conveyors

The FR-F700 offers a range offeatures that benefit most mo-tor applications. These featuresalso make the FR-F700 ideal forfan and pump applications.

Freewheeling occurs when exter-nal pressures turn a nonpoweredmotor in either direction, forexample static head pressureforces a pump to rotate. Startinga motor in this state could causea motor to trip under an overloadcondition. The FR-F700 virtuallyeliminates this problem.

When the FR-F700 is started it canautomatically sense direction andspeed of the motor, bringing itunder control immediately - oftencalled a flying start.

With an automatic restart after abrief power outage, the Inverterautomatically "catches" themotor while it is coasting andaccelerates it to its preset speedproviding immediate recoveryand minimal loss of control.

For the best performanceunder difficult load conditionsa 5-point V/f torque curve canbe set to match systemscharacteristics.

Sometimes a powered motorcan be overdriven by its load,the motor then acts as a gener-ator and can create high volt-ages within the drive. TheFR-F700 can increase its outputfrequency to avoid tripping.

Optimum motor protectioncan be achieved by connectingthe motor's PTC temperaturesensor to the drive's tempera-ture monitoring system.

The FR-F700 can automaticallyoperate up to four load-con-trolled motors from a singleinverter. As each motor isbrought up to speed it is thenswitched 'direct on line' allow-ing the next motor to be con-trolled. Slowing, is a reverse ofthe same process.

The FR-F700 easily handlesHVAC applications that requirelocal PID control or can act aspart of a larger buildingnetwork such as LON Works.

The FR-F700 can achieveparticularly impressive powersavings in the low speed rangeand during the accelerationand braking phases. Forexample, at a frequency of35Hz it uses 57% less powerthan conventional solutions.And the pioneering OEC(Optimum Excitation Control)function cuts consumption byanother 10%. OEC ensures thatthe motor always gets theoptimum magnetic flux, formaximum motor effectivenessand efficiency.

A combination of many intelligentdesign features and newly devel-oped components (includingthe fans and capacitors) haveincreased the service life of theFR-F700 to over 10 years. Anautomatic warning is displayedwhen the end of the service lifeis approaching, so that you canavoid unexpected failures.Setup is fast and maintenance issimple, thanks to preconfiguredparameters, fast and easyparameter configuration andeasy replacement of compo-nents like fans and terminalblocks when necessary.

Assuming an application witha 75 kW motors, an electricityprice of �0.14 per kWh, thecost calculations are as follows:

Conventional mechanical solutionAir volume 60%, power consumption 90%*:75kW x 0.9 x �0.14 x 24h x 365 days = �82,782

FR-F700 frequency inverter solutionAir 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

● Average value in kWh,% or money units

● Annual value kWh ormoney units

The VFD setup softwarepackage (runs underWindows® 95, 98, ME, XP, NTand 2000) is a powerful tool

for configuring and operatingyour Mitsubishi frequencyinverters. In addition tooperating the inverter from astandard personal computer ornotebook you can also use VFDsoftware to configure, operateand monitor multiple invertersin a network system.

The software packageincludes functions for:● System configuration and

parameter settings

● Display and diagnostics

● Testing

● File management and help

The integrated one-touchDigital Dial gives you muchfaster access to all theimportant parameters thanwould be possible usingconventional control keys.

The removable FR-DU07control unit makes operatingthe inverter simple andintuitive. A 4-digit LED displayenables you to check and editsettings, and it is also used formonitoring operating statusand displaying alarms. Youcan monitor all inverter and

motor status parameters andthe error code displays enablerapid troubleshooting. Thecontrol unit can also be usedto adjust the speed of theconnected motorcontinuously and directly, andto copy sets of configurationparameters from onefrequency inverter to another.The unit can be connectedwith a cable and installedremotely, for example in anexternal cabinet.

The optional FR-PU04 featuresa backlighted, long-life LCD

screen, a user interfaceselectable in one of eightdifferent languages and anumeric keypad for direct entryof settings and operatingparameters. It is connected tothe FR-F700 with a cable, alsoallowing remote installation ina cabinet.
