Based on the new Development platform SD4x developed Sieb & Meyer now a future-proof one inverter Family. The frequency converter support new ones interfaces as Profinet, Ethercat or bite and offer a number 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.
The converter family SD4x offers a significantly improved processor performance: The new 5-bit processor is up to 2 times faster than with the current SD32x product family. It allows a higher resolution and more accurate calculations. Sieb & Meyer has also switched from fixed-point to floating-point arithmetic. This allows the inverters to be designed more flexibly.
With the new processor, more complex tasks can be solved faster and control technology solutions with higher resolution and dynamics can be implemented. On the storage side, the 500-fold larger storage was also significantly increased. In summary, the optimized performance, higher speeds and low motor warming without sine filters are the main advantages of the SD4x converter family. The improvements allow completely new areas of application.
Inverters for high-speed spindles
The SD4S converter was designed for small high-speed spindles and motors in the power range of a few hundred watts. It is used, for example, in dental milling machines or machines for fine machining as well as for the watch industry. Because the necessary insulation strength is often not provided in the motors for small spindles, the SD4S now enables electrical isolation of the thermal contact. The overall width is only 40 mm.
The parameters are set via a standard Ethernet interface, which replaces the fault-prone USB interface. The SD4S also has configurable digital interfaces for measuring systems such as Biss-C, Endat2.2 and TTL. A web server enables information to be called up without additional parameterization software. The integrated real-time clock allows interactions with external events or processes and an exact analysis of errors.
Sieb & Meyer will continuously expand the performance classes of the SD4S.

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.

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 universal drive controllers "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 additional power levels up to 450 kW for the encoderless and encoder-dependent control of different motor technologies (ASM, SSM, IPM, SynRM).
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.
