Baumüller of Germany will be presenting numerous new products at the SPS 2019 trade fair from November 26 to 28 in Nuremberg. The company will be displaying clever motor concepts, intelligent drive functions and powerful control platforms on various stations. The connectivity and interoperability of components via OPC UA and cloud connectivity will be presented in the Industry 4.0 area.
Baumüller components extended to include IoT connectivity
Baumüller is extending its components to include further, extensive IoT functions. This makes it easy to network and control of machines and machine modules through to individual automation components. With the new IoT functions, data can be collected, pre-processed and output directly at other terminal devices or on the cloud. They make extensive and complex data analyses possible, in order to enable Industry 4.0 applications, such as predictive maintenance. At the same time, new business models, such as “x per use” can be achieved.
Individual parameterization for the analysis of data through to creation of their own dashboards by users can be undertaken directly on the component. The available MQTT module allows data to be read in from different clouds; regardless of the respective cloud provider. It also includes an OPC UA module, which ensures interoperability at machine level.
With Node-Red, the components have a graphic parameterizing interface (flow based), so that data can be analyzed, further processed and visualized directly at the machine.
Data from different manufacturers’ devices can be processed. Data from Baumüller products, for example, of a b maXX converter, can be output in parallel to the fieldbus via the internal protocol and thus via the service interface. Due to the enhanced functions, the connectivity of Baumüller devices, such as the b maXX PCC04, with other automation components can be established via OPC UA.
New generation of the b maXX 5300 module systems – higher security functions, greater flexibility
The b maXX 5000 converter family has convincingly high-performance power units, flexible expandability and an integrated communication concept. With the new edition of the b maXX 5300, Baumüller is revising its module systems and is making them even more powerful and flexible for customer use. Thanks to numerous hardware and software options, in future, customer and application requirements can be met with even more granular solutions. For example, the number of secure I/Os can be adjusted to the respective requirements of the application.
In addition, new security functions are integrated in the b maXX 5300, such as transfer of the secure
position via FSoE to a high-level safety control. With this function, secure space monitoring and secure collaboration between several axes can be implemented, for example, in robotics applications.
Higher accuracy with regard to encoder resolutions is possible with the new devices. Thus, used with security technology with a single resolver, the device has a speed resolution of less than 1 rpm. This high position and speed accuracy is particularly important for highly dynamic applications, for example, for textile machines or handling systems.
A further advantage is the faster response time to events: For example, on triggering the STO security function, the controller is switched without torque with a delay of less than 1 ms.
In addition, the ETG standard for FSoE communication is implemented with the new generation of the module systems. This means that the b maXX converters can also be easily linked to higher-level safety controls of other manufacturers.
Intelligence in the drive
The intelligent converters of the Baumüller b maXX 5000 product family with integrated softdrivePLC enable data analyses directly in the drive. In this way, logic operations cannot only be parameterized, but also be programmed. An example: If the control circuits vibrate due to resonant frequencies, this vibration can be minimized with the help of a more dynamic setting and productivity is increased.
Vibrations in the mechanics can also be filtered out with the intelligent b maXX converters. Numerous controller functions are integrated in the b maXX 5000 series, to make the system even more efficient and intelligent. Functions such as transmission protection, adaptation of the controller parameters, error reactions or monitoring the thermal pump load via a temperature model ensure lower service costs, shorter standstill times and lower system costs.
Numerous features: The new servo pump software version V2+
The adaptive pressure pre-control is a significant improvement of the software modules of the control function in the new servo pump software version V2+. The intelligent control algorithm adjusts adaptively to different pressure rise rates; this means that the parameterization only has to be set once and is then automatically regulated. The software enables an overshoot-free pressure jump in minimum time, thus ensuring an optimized process sequence. Since the corresponding parameters adjust automatically with a standard cycle of 125 µs during the production process, the adaptive control eliminates or greatly reduces pressure overshoots. The required pressure value therefore sets in fully automatically with controlled transition.
The experts at Baumüller have enhanced the new software version V2+ of the servo pump to include several protection functions, so that wear of highly loaded parts of the servo pump does not influence the quality of the end products and also the load on the machine components is reduced. For example, by default, the pump load is monitored within highly loaded pressure maintenance mode. If the temperature model indicates a thermal overload, the bypass valves open automatically to remove the overheated oil. The servo pump is cooled until it has returned to normal temperature. A further positive aspect of the monitoring concerns the leakage characteristic. In the new version, this can be additionally recorded and compared with reference data. This makes diagnosis easier and wear or necessary replacement of the valves and seals can be detected faster.
