【正文】 ion current and the activecurrent via the motor model. With thepatented multivariable control system, thevectors of both ponent currents areadjusted so exactly in accordance with thedialog, that the highest possibleutilization of the motor and driveconverter bination is guaranteed.Patent document:44 18 997 from 2/6/99, German Patent andTrademark Office, MunichREFUdrive 500Drive Converters with Internal Liquid CircuitBlock Diagram REFUdrive 500Electromagnetic Compatibility EMCElectromagnetic patibility EMCDrive converters control the torque androtary speed of three phase inductionmotors using a pulsewidth modulatedoutput voltage with variable frequency.To reduce power losses, fastswitchingsemiconductors are used, which ensureefficient controlling at high cycles.Electric and electromagnetic noise fieldsare usually a result of this.The limiting values for the permissiblenoise emission of drive convertersare stated in the European StandardEN 55011. This standard differentiatesbetween voltage interference on thepower supply due to the cables andradiated interference or radiointerference. The standard defines thelimiting values A for industrial powersupplies and B for connection to publicpower supplies.The REFUdrive 500 drive converters haveintegrated radio interference suppressionfilters and line reactors to reduce theharmonics fed back into the line supply.The units pletely fulfill the EMCDirective in reference to the noiseimmunity and noise emission according tothe EMC Product Standard for electricdrives EN 618003, EN 55011 class A(IEC18003) and the noise immunityspecifications according to EN 500822.Radio interference suppression filters areavailable as accessories for plyingwith radio interference degree B accordingto EN 55011.Measures for ReducingNoise EmissionLine filters are used to reduce the spreadof noise emissions into the power supply.Shielded motor cables with shields fittedon both sides direct the noise emissionson the outside back to the drive converter.To reduce noise radiation, the driveconverters are assembled into a closedcabinet. Power and control cables are tobe laid at a safe distance apart. The wholeentrance to the cabinet must be wellshielded.REFUdrive 500Drive Converters to 110 kWOutput frequencies up to 200 HzTechnical DataLine supply voltage4 3phase AC 380 to 480 V 177。 10 % with braking chopper,integrated line contactor as well as liquid cooling withintegrated heat exchanger for a 132 kW motor.1 Version51 VFC Voltage Frequency Control52 FVC Flux Vector ControlRD52?14B132FRated motor outputL i ne s uppl y v ol t agePeak currentL i ne s uppl y v ol t agePeak currentSi ze45 ly e A volta0V C ge 177。 10 %5 3phase AC 500 V 177。 8 bit, reference as selected +10 V, 10 V? 1 relay output 250 V AC, 7 A or 30 V DC, 7 A?

It is reassuring foryou that we are there when you need us around the clock, worldwide.Traditionally innovativeInnovation is our driving factor. We havecontinuously set milestones in drivetechnology, which have later bee”state of the art”. Our aim has been, andstill is, to develop new applications forfrequency converters in connection withsychronous and induction motors. This istradition in our pany: Just three yearsafter the pany’s establishment in1965, we had already produced afrequency converter for highspeed drillingspindles, and shortly afterwards the firstfrequency converter with thyristors. Laterwe developed the new generation ofconverters with IGBT’s and highperformance microprocessors. We arenowadays setting new standards with themodularconstructed REFUdrive.The Drive amp。 132 kW and output frequency 150 HzW1 Power code 179。 Hold module ? Mathematical function elements ?
