The values can beadjusted particularly finely within theusual setting ranges. For soft starterswith motor overload protection, this alsoapplies to the nominal motor current, theselection of the tripping class and thesettable current limiting.The multiple functions of our high-featuresoft starters are set rapidly and comfortablyvia the integrated keypad withmenu-prompted graphical display.Also commissioning and diagnostics arerealized via this keypad.Why is torque control the bettersolution?Current and voltage fluctuations uponstart-up are problems frequentlyencountered by operators of power supplysystems. Your machines are then stressedby abrupt torque fluctuations. The softtorque control of our high-feature softstarters minimizes the maintenanceexpenditures for your machines.How about motor overload protection?No problem: Our soft starters come withintegrated motor overload protectionfor many applications. This does awaywith additional wiring costs and evenprotects the soft starter against overload.For all other cases, you can utilize theadvantages of our further SIRIUS devicesfor the control cabinet by employing ourcircuit breakers or overload relays.

Also for smooth motor startusing our soft alternative, two controlledphases are sufficient with standard softstarters. Moreover, our solution not onlysaves costs, but also space in the controlcabinet. However, the third controlledphase is required for inside-delta circuits.What are the benefits of settablecurrent limiting?More and more power supply companiesrequest compliance with specific currentlimit values during start-up to minimizethe load on the power supply systemsposed by high starting currents.

However, thisis only reasonable if the motor’s speedis to be influenced also during operationin addition to the starting phase – whichincreases the costs.* star-delta7


Soft Starters for Standard ApplicationsSIRIUS 3RW30 and 3RW40Thanks to their compact design, integrated motor overload and intrinsic deviceprotection, settable current limiting and further features, SIRIUS soft starters arethe ideal starter solution for all kinds of standard applications.8


In the past, typical starter solutions forstandard applications were based ondirect and wye-delta* starting. Today,the advantages offered by soft startersolutions are increasingly utilized.SIRIUS soft starters, for example, notonly improve the start-up behavior ofescalators, elevators, conveyor belts andpumps, as they simply facilitate a softerstart-up than electromechanical starters.Above all, they protect the drive systemand the mains supply and thus contributeto reducing the system costs from manypoints of view.To allow for an optimum adjustment ofyour drive to the application, we offera complete portfolio of soft starters invarious sizes for almost any applicationarea. For example, the two-phasecontrolledSIRIUS 3RW30 is particularlysuitable for standard applications up to55 kW. SIRIUS 3RW40, which additionallyoffers motor overload, intrinsic deviceand thermistor motor protection, alsomasters demanding tasks in a softmanner within the power range from5.5 to 250 kW.* star-delta9


Conversion Made EasySIRIUS 3RW30 in DetailBelt slippage with heater blowers or sudden water pressure build-up in washingsystems are only two of many possible problems which may occur if motorsoutput too much power directly upon start-up. With the SIRIUS 3RW30, suchfailures are reliably prevented up to 55 kW (with 400 V). The main advantage:As the SIRIUS 3RW30 is the world’s only soft starter which offers identical sizeswithin one device range, it even allows for a direct conversion from direct to softstarting.10


What are the advantages of softstarting?The advantages are multiple, as theSIRIUS 3RW30 reduces the stress on themotor by reducing the start-up torqueand protects the mains against hazardouscurrent peaks through reduced currentinput. This reliably eliminates line voltagedips.What are the benefits of the SIRIUS3RW30?The SIRIUS 3RW30 is particularly compactthanks to its consistently optimizedpower components in hybrid technology.It thus also facilitates side-by-side assemblyup to 60 °C. It offers fast configurationand easy mounting with only 3 motorsupply cables. Small fuseless load feederscan be assembled with a single module –with the SIRIUS 3RV circuit breaker. Alsofused feeders can be realized in a fast andspace-saving manner in combination withSIRIUS 3RB solid-state overload relays.What about safety and reliability?Thanks to two-phase control and thepatented “polarity balancing” controlprinciple, the SIRIUS 3RW30 is adependable device which ensures safeand reliable operation. In addition,the integrated bypass contact systemreduces the soft starter‘s heat lossduring operation.What are the application areas?The SIRIUS 3RW30 can be employed inalmost any standard application up to amotor rating of 55 kW with 400 V. Forexample for driving conveyor belts, compressors,grinding machines, saws, agitators,etc.With the SIRIUS 3RW30 in size S0 (45 mm),up to 38 A can be switchedHow is the SIRIUS 3RW30 set?Ramp-up time and starting voltagecan be comfortably and easily set via2 potentiometers, ensuring optimumstarting behavior.How is the soft starter controlled?Without interface relays, the SIRIUS3RW30 can be directly controlled viathe PLC – or via the control input. Therespective operating state is signaled viaa relay output.What are the saving potentials?Space savings in the control cabinet upto 70% are achievable compared to wyedelta*starters (example 18.5 kW: 45 mmwidth instead of 158 mm). The SIRIUS3RW30 also pays off in terms of mounting:with only 3 instead of 6 motor supplycables.The 3RW30 is also available withremovable control terminals. Whenreplacing a 3RW30, the wiring on theterminal thus remains intact (“permanentwiring”) and the terminals are simplysnapped onto the new 3RW30, whichsaves a considerable amount of time.Is the SIRIUS 3RW30 affordable?Absolutely, as it not only ensures reliableoperation thanks to standardizedproduction, but is also very attractive interms of price.How about accessories?In addition to easy-to-mount terminalcovers for optimum touch protection,also box terminal blocks, connectionmodules and labeling strips from theSIRIUS range are available for the 3RW30.* star-delta11


High Functionality for Minimum CostsSIRIUS 3RW40 in DetailThe SIRIUS 3RW40 is the top star among all standard soft starters! Thanks to its innovative controlprinciple, it is not only the world’s only two-phase-controlled soft starter in the power range from5.5 kW (with 400 V) to 250 kW (with 400 V), but is also the smallest available solution thanks to itsparticularly compact design. It facilitates space-saving and transparent control cabinet arrangementsand is thus more than a supplement of our two-phase-controlled SIRIUS 3RW30 soft starter range.What are the benefits of theSIRIUS 3RW40?The SIRIUS 3RW40 soft starter isseamlessly integrated in our SIRIUSportfolio for the control cabinet. As youmight already know from experiencewith other SIRIUS devices, you will thusbenefit from identical sizes and uniformconnection systems. Regarding size: theparticularly compact design of the SIRIUS3RW40 is at most half as big as that of acomparable wye-delta* starter, makingspace wastage in the control cabinet athing of the past. Also configuration andmounting are realized rapidly and easilythanks to 3-conductor connection.What are the differences compared tothe SIRIUS 3RW30?In general, the SIRIUS 3RW40 offers allthe advantages of the 3RW30.In addition, it offers intrinsic device protectionand integrated motor protectionfunctions. Just test it and you will beconvinced.* star-delta12


How is the SIRIUS 3RW40 set?Like with the SIRIUS 3RW30, the startingvoltage, ramp-up and ramp-down time ofthe voltage ramp, as well as the currentlimiting, can be comfortably set via finelyadjustable rotary potentiometers. Thenominal motor current, trip class andreset of the motor overload function areadjusted via potentiometers and buttons,as is familiar from the SIRIUS overloadrelays.What are its outstanding characteristics?The SIRIUS 3RW40 comes with the newpatented control principle “polaritybalancing” for the avoidance of DCcomponents in two-phase-controlled softstarters. With two-phase-controlled softstarters, the current resulting from theoverlapping of the two controlled phasesflows in the uncontrolled phase.For physical reasons, this results in anasymmetric distribution of the threephase currents during the motor’s startupprocess. Even though this distributioncannot be influenced, it is uncritical inmost applications. However, besides thisasymmetry, the power semiconductors’control during the two controlled phasesalso produces the above-mentioned DCcomponents, which may lead to a loudmotor noise with starting voltages lowerthan 50%. “Polarity balancing” reliablyeliminates these DC components duringthe start-up phase. It generates an evenmotor start-up in terms of speed, torqueand current rise. The acoustic qualityof the start-up process almost reachesthe quality of a three-phase-controlledstart-up. This is made possible by thecontinuous dynamic alignment andbalancing of current half-waves withdifferent polarity during the motorstart-up.Does the SIRIUS 3RW40 featureadditional protective functions?The SIRIUS 3RW40 is equipped with optimumfunctionality as standard. An integratedbypass contact system reducesthe soft starter’s heat loss during operation.This reliably prevents heating ofthe switching device‘s environment. Theintegrated motor overload protection inaccordance with IEC 60 947-4-2 makesan additional overload relay unnecessary;this saves space in the control cabinet andreduces the wiring costs in the feeder. Theoverload trip class can be variably set via a4-level rotary potentiometer. In addition,intrinsic device protection prevents thethyristors’ thermally overloading and resultingdefects of the power components.Optionally, the thyristors can also beprotected against short circuit with SITORsemiconductor fuses. Also inrush currentpeaks are reliably eliminated, thanks tosettable current limiting.Does the SIRIUS 3RW40 offerdiagnostics options?Yes, thanks to integrated status and faultmonitoring. LEDs provide information onthe operating state as well as possiblefaults, e.g. impermissible release time(CLASS setting), mains or phase failure,missing load, thermal overload or devicefault. The two integrated output relaysalso indicate the operating state and faultsignals.Is thermistor motor protectionavailable?Device versions with thermistor motorprotection evaluation are available upto a rating of 55 kW (with 400 V). A“Thermoclick” measuring sensor or PTC(type A) can be directly connected. Inaddition to thermal motor overload, wirebreakage and short circuit in the sensorcircuit effect a disconnection of the softstarter.What about reset options?After the soft starter has tripped,various reset options are available, likefor intrinsic device and motor overloadprotection: manual or via the resetbutton, automatic or (up to 55 kW)remotely via short-term control voltageinterruption.Is replacement easy?Yes, also the 3RW40 is equipped withremovable control terminals. The wiringon the terminal thus remains intact(“permanent wiring”) in case of replacementand the terminals are simplysnapped onto the new 3RW40, whichsaves a considerable amount of time.How about accessories?We offer a comprehensive range ofaccessories for our soft starters, e.g.box terminal blocks, accessories formechanical reset and a module forremote reset (for ratings > 75 kW) as wellas a sealing cover and easy-to-mountterminal covers for optimum touchprotection.Furthermore, snap-on fans are availablefor the devices up to 55 kW whichfacilitate mounting of the SIRIUS 3RW40in almost any installation position andsupport higher switching duties. In addition,connection modules for electricaland mechanical connections betweencircuit breaker and soft starter as well aslabeling strips from the SIRIUS range areavailable.13


Soft Starters for High-FeatureApplicationsSIRIUS 3RW44 in DetailEquipped with maximum functionality, the all-round talent SIRIUS 3RW44 even masters difficult start-upand stopping processes in a soft manner. Thanks to innovative torque control, it can be employed for drivesup to a power rating of 710 kW (with 400 V) in standard circuit or up to 1200 kW in inside-delta circuit. Thefunctionality designed for ease of operation facilitates optimum operating comfort.What are the benefits of theSIRIUS 3RW44?Thanks to its particularly compact design,which is a characteristic of the entirerange of SIRIUS soft starters, the SIRIUS3RW44 is the ideal solution when spacesavingand transparent control cabinetarrangements are required. For optimizedmotor start-up and stopping, the innovativeSIRIUS 3RW44 offers an attractiveand efficient alternative to frequencyconverters. The new torque control and asettable current limiting allow for the useof our high-feature soft starters in almostany application.The SIRIUS 3RW44 guarantees reliableprevention of torque surges and currentpeaks during motor starting and stopping.This reduces costs both for switchboarddimensioning as well as machinery maintenance.Whether for standard (in-line) or insidedeltacircuits – the SIRIUS 3RW44 offerssaving potentials, particularly in terms ofsize and device costs.14


How is the SIRIUS 3RW44 commissionedand operated?Commissioning of the SIRIUS 3RW44 isparticularly fast and easy, thanks to amodern and ergonomic menu system.This is facilitated by a keypad with amenu-driven, multi-line graphical displaywith background illumination. Theoptimized motor start-up and stoppingcan be realized rapidly, easily and safelyvia only few settings in several preselectedlanguages. 4-key operation andplain text displays on every menu itemensure transparent parameterization andoperation at all times. Via the displayfield, measuring and operating values, aswell as warning and fault messages, arecontinuously displayed during operationand with the control voltage connected.In addition, an external display and operatormodule can be connected to the softstarter via a connection cable, for exampleto read actual values directly from thecontrol cabinet door.Does the SIRIUS 3RW44 featureadditional protective functions?The SIRIUS 3RW44 is equipped withoptimum functionality as standard.An integrated bypass contact system reducesthe soft starter’s heat loss duringoperation. This reliably prevents heatingof the switching device‘s environment.Moreover, it features an internal deviceoverload protection against thermal overloadof the power section’s thyristors, e.g.caused by impermissibly high startingoperations.The wiring costs for installation of anadditional motor overload relay areeliminated as the SIRIUS 3RW44 alsomasters this function. Whether settablerelease times or thermistor motor protection:With SIRIUS 3RW44, you are alwayson the safe side! Optionally, the thyristorscan also be protected against short circuitwith SITOR semiconductor fuses. Also inrushcurrent peaks are reliably eliminatedthanks to settable current limiting.Is the SIRIUS 3RW44 communicationcapable?Yes, the SIRIUS 3RW44 can be optionallyretrofitted with a PROFIBUS DP module.Thanks to its communication capabilityas well as its control inputs and programmablerelay outputs, it can be very easilyand rapidly integrated in superior controlsystems.What are the advantages in terms ofpower loss?Normally, approx. 3 W heat load are generatedper every ampere flowing throughan actuated thyristor. For motors with250 kW (with 400 V), this results in aheating power of roughly 1500 W in theswitching device‘s environment.The SIRIUS 3RW44 coolly handles thesehot conditions. As a standard, all versionsare equipped with mechanical bypasscontacts, which bridge the thyristors afterdetected motor start-up. This considerablyreduces the heat loss occurring duringthe soft starter’s nominal operation.The intelligent hybrid concept, whichelectronically starts the motor via thyristorsand operates it electromechanicallyvia contactor contacts during rated operation,improves the feeder’s overallefficiency and additionally reduces thecosts for control cabinet dimensioning.What if lower speeds are required?For positioning and set-up tasks, a creepspeed function allows for the motor’scontrol in both directions of rotation –with reduced torque and settable lowspeed.What about stopping quickly?For the fast shutdown of driving loads,a new, combined DC brake function isoffered for the SIRIUS 3RW44.How about accessories?We offer a comprehensive range ofaccessories for our soft starters, e.g. anexternal display and operator module forinstallation in the control cabinet door orthe plug-on PROFIBUS DP module.Circuit breaker and soft starter as well aslabeling strips from the SIRIUS range areavailable.Furthermore, easy-to-mount box terminalblocks and sealing covers from the SIRIUSportfolio are available for optimum touchprotection.15

Due to the milling head’s highinertia, shutdown of the 15-kW motoris subject to long stopping times, whichcause long downtimes for tool changesand set-up operation.The start-up behavior of millingmachines requires maximumfunctionality■ To prevent excessive wear of the drivebelts due to slippage, milling machinesrequire an optimized and torque-controlledstart-up behavior.■ The motor’s starting current has to bereduced to minimize the mains load.■ The motor has to be braked with DCcurrent to reduce the machine’s longstopping times.Competent solution with SIRIUS 3RW44■ To optimally master the difficultstarting conditions, the SIRIUS 3RW44with torque control and dynamic DCbrake function is employed.■ Slippage of the belts during start-up isprevented by torque control with adjustedtorque limiting function.■ This rapidly accelerates the millinghead to the nominal speed withoutslippage of the belt drives.■ A higher-level current limiting functionreduces the motor’s starting current toa set maximum value.■ The optimum setting of the dynamicDC brake function shuts the millinghead down in minimum time.■ Also motor and device overloadprotection is excellently mastered bythe SIRIUS 3RW44 high-feature softstarter.21
