Geared motors

Technical data - MotorsMotor connectionstarttec motor starterTrend towards distribution even on switchgearThe increasing relocation of control and switching componentsfrom the control cabinet to the system process andthe demand for additional distributed functions to relievecentral PLCs has increased the popularity of distributeddrive components.HistoryMotor starters have until now been used as electromechanicaland electronic switchgear in the control cabinet forswitching and protecting three-phase AC motors up to4 kW. This generally requires star-type wiring which is extremelycomplex to install.The current situationSwitchgear and drive components operate decentrally, i.e.they intervene directly in the process. Integrated protectionfeatures ensure the reliable operation of the motor, additionalfunctions relieve the load on the central PLC and providebenefits by reducing the time and effort required for projectplanning and commissioning. The entire distributed drivesystem therefore provides maximum levels of flexibility,high plant availability and is extremely cost-effective.starttec – tailored to meet the requirements of materialshandling applicationsEconomic˘ Small number of models: one size for the power range0.25...4 kW˘ Start-up ramp to protect mechanics˘ Power bus makes installation easier˘ Easy to retrofit, e.g. on standard motors or if the starttechas been mounted on the wall˘ Integrated brake control (option) with configurable timedelay, reduces the load on the PLCSafe˘ Can be commissioned by non-experts˘ Reduction of high start-up currents˘ Integrated motor protection via overload/temperature protection (thermal contact/PTC)˘ Robust due to high enclosure IP65/NEMA 4(in preparation)˘ Wear-free, even at high operating frequency˘ High plant availability due to error reset option/handheldoperation˘ Status display directly on the starttecVersatile˘ Optimum access due to mounting on the wall or on themotor˘ Actuation via– digital I/Osand/or– fieldbuses (INTERBUS, PROFIBUS-DP, CAN system bus,DeviceNet/CANopen, AS-Interface)˘ Collection and linking of input signals forforwarding to the PLC/fieldbus˘ Multi motor operation (option)˘ Change of direction of rotation (option)˘ Flexible due to configurable tripping characteristic88-10 G-motion const en 11/2004
