Sensorless security for various motor technologies
The universal drive controller "Combivert F6" from KEB Automation are frequency converters, servo or special drives in one device. They simplify the selection in drive applications and thus optimize storage, logistics and costs. In addition to the four housing sizes with nominal powers up to 90 kW, there are now further power levels up to 450 kW for the encoderless and encoder-dependent control of different motor technologies (ASM, SSM, IPM, SynRM).
High overload capacity, the quick response to load changes or the universal connection to higher-level control systems - with these properties, the Combivert F6 implements dynamic tasks in machines and systems, cranes, elevators or lifting devices in the best possible way.
In addition to the particularly compact design, protective-coated assemblies and high vibration resistance optimize operation in harsh environmental and operating conditions. With the “All-in-One” concept, the devices offer a convenient control panel, protection of the supply network thanks to the choke and EMC filter, and functional safety via the safe torque switch-off. The selection and installation of the devices is as simple as their operation: Use and handling is made easy with the commissioning and diagnostic software "Combivis 6" with numerous wizards.
Logimat Hall 3, Stand C17; Hannover Messe Hall 5, Stand D17 Cover story No matter whether they are used in Europe, China or the USA: The cradle of every Nordac Link is in the Nord Drivesystems manufacturing plant in Aurich, East Frisia. The drive specialist started serial production of its new field distributor series Nordac Link in 2017. The comfortable drive solution for flexible, decentralized installation is manufactured at the Aurich location. A look behind the factory gates.
Hannover Messe Hall 27, Booth E50 Celeroton presents a special converter that is used to control compressors in fuel cell systems. The CC-550-7500 allows sensorless control of brushless DC motors (BLDC) and permanent magnet synchronous machines (PMSM). The modulation and control can be matched to almost any electrical machine. This guarantees maximum efficiency in the converter and minimal motor losses.
Based on the new SD4x development platform, Sieb & Meyer is now developing a future-proof converter family. The frequency inverters support new interfaces such as Profinet, Ethercat or Biss and offer a range of additional functions. Higher speeds and significantly better performance await the user. The developers start with the SD4S converter. The frequency converter is designed for small high-speed spindles or high-speed motors in the power range of a few 100 W.
With the "Nordcon App" and the Bluetooth stick "Nordac Access BT", Nord Drivesystems has created a mobile commissioning and maintenance solution for control cabinet and frequency inverters. Both tools are used for drive monitoring on the converter from the north via dashboard, its analysis using a convenient oscilloscope function and its parameterization. In addition to the drive monitoring, the dashboard-based visualization can also be used for fault diagnosis of the frequency inverters.

The Danfoss Drives Troubleshooting Chatbot provides targeted information on how to eliminate errors in the manufacturer's frequency inverters. The user only needs the converter series and the error code shown on the display or system. This means that the digital helper can immediately provide information on the cause and tips on elimination.
SPS Hall 1, Booth 124 Sprint Electric has modified its 3200i and 3600XRi DC converters. The innovations in both series increase the adaptability, performance and durability of the two and four quadrant DC controllers. Both versions can be used to control the speed and current of most brush-type DC motors.
The future of production is modular, flexible and autonomous. This requires new systems with decentralized intelligence that can cope with the growing complexity of the processes. Nord Drivesystems supplies a wide selection of decentralized drive technology with frequency converters that can be individually adapted to any desired application and can be flexibly integrated into the system field.
