Second generation of

Second generation of safety PRODUCTS SPS Nuremberg represents Kollmorgen as a sign of complete drive solutions, including for the growing demand for collaborative robots and automated guided vehicles (AGV). The AKM2Gseries servo motors were therefore also expanded for applications in the low-voltage sector. Also a topic at the three-day automation trade fair: the second-generation functional safety technology, which has found its way into the AKD2G series servo inverters. For the second generation of servo motors, the control arm is at full throttle. The high power density with greater torque per engine size opens up new ways to construct machinery since a smaller overall size is often sufficient to handle the AKM2G. It is compact applications with a high functional density that benefit from this feature; for example, in the design of collaborative robot kinematics and AGV. Intelligent safety for small brakes Machines and systems are producing increasingly high performance densities and working at higher speeds. This means that the requirements on the individual components are also increasing. Mayr power transmission therefore provides high-performance safety brakes, for example their Roba-servostop series. These are ideal for installation into servomotors. A special hollow shaft design in slim constructional design and of a low weight has been especially tailored to requirements in robotic applications. In addition, the company has a fluid-free linear brake in its portfolio with its Roba-linearstop in electromagnetic design, which has been designed to secure gravity-loaded vertical axes. This brake type is used in applications in which compressors or units for compressed air or oil hydraulics are not available or are unwanted - such as in the field of medical technology or the food or pharmaceutical industry, where high hygiene standards are required. The intelligent Roba-brake-checker module now opens up new possibilities for brake monitoring, also in these application areas. With a new module design and thanks to even more accurate evaluation, it is now possible to also supply and monitor small brake sizes from a braking torque of 2 Nm. This makes the Roba-linearstop not just the only electromagnetic rack and pinion brake on the market, but it also means it can be monitored even in small construction sizes with the aid of the module. The Roba-brake-checker module works without sensors. It detects the movement of the armature disk through extended analysis of current and voltage, and knows what condition the brake is in. In addition to the switching condition, temperature and wear, the Roba-brake- checker also monitors the pull-in distance or tensile force reserve, i.e. whether the magnet is still able to attract the armature disk. Future-oriented: Web-based visualization system Siemens is presenting a completely new overall system for industrial operator control and monitoring. The web-based visualization system consists initially the Simatic WinCC Unified visualization software as well as the new generation of HMI panels, Simatic HMI Unified Comfort Panels. The new system provides the user with a solution for HMI and SCADAapplications, and in the future also for Industrial Edge, Cloud and Augmented Reality scenarios. The runtime of the newly developed visualization software Simatic WinCC Unified in the TIA (Totally Integrated Automation) Portal is based on native Web technologies such as HTML5, SVG and JavaScript. I/O modules increase the operational reliability Interferences are common on decentralised machines and production lines, process plants as well as marine and offshore applications, due to ground loops or line-induced field influences. For these kinds of applications, Weidmüller has developed the new “UR20-8DI- ISO-2W” and “UR20-4DO- ISO-4A” I/O modules. Thanks to the galvanic isolation of min. 500 V between the channels and the system, this enables uninterrupted operation, even in loaded applications. The channels are protected against mutual interference and also against external disturbances. They provide a high output density with maximum flexibility. With just 11.5 mm width, the new modules meet the requirement for compact and space-saving automation solutions, and are thus the ideal addition to the u-remote product family. 20 WORLD OF INDUSTRIES 6/2019

Costumer focused solutions for smart engineering Digital and product related services are also playing an increasingly important role in the drives industry. Against this background, Wittenstein alpha will unveil a value-added service portfolio – the web based “Wittenstein Service Portal” – which is individually tailored to the needs of fitters, maintenance technicians and commissioning and service engineers. As of November 2019, details of all standard products from Wittenstein alpha, Wittenstein cyber motor and Start-up Galaxie can be displayed on a Service Portal website for each individual product. All relevant product information such as technical data, video tutorials, documentation, add-on components and accessories, successor models can be accessed there easily throughout the lifecycle together with numerous other services. Gearboxes with cynapse – in other words, with an integrated sensor module and an IO-Link interface – are likewise incorporated along with smart services, so that the Service Portal simultaneously builds bridges to Wittenstein components used in IIoT environments. Fully clamped The hydromechanical spring-loaded cylinders of the ZSF series from Jakob Antriebstechnik offer robust and reliable clamping elements. These spring-loaded systems can be used wherever displaceable or movable machine parts must be temporarily clamped or locked. Other applications can be found in jig construction and for workpiece or tool clamping. The spring-loaded systems interact mechanically-hydraulically. The clamping force is applied mechanically by a prestressed plate spring package. The hydraulics are only needed for the release stroke of the elements, whereby the tie rod or pressure pin is released. This system ensures a high level of operational safety, since the clamping force is always maintained at full height, regardless of oil pressure or leakage losses. background: fotolia Can an e-chain ® be filled without tools?
