New: POS-123-P-PFN

New: POS-123-P-PFN

New to our family of hydraulic axis positioners is now a module with integrated power stage and Profinet interface. This combination allows cost-effective and robust proportional valves to be used without internal electronics. The Profinet interface enables seamless data exchange with the machine control system. Setpoints and actual values are transmitted digitally and without loss of accuracy. Extensive diagnostic information is available. The unit can be fully parameterised via the free WPC-300 program as well as via the Profinet interface. For this option, we provide a convenient function block for controllers of the Simatic S7 series. This also makes it possible to save parameter sets in the PLC and automatically write them back in the event of a device replacement.

Perfect synchronisation

Perfect synchronisation

With the UHC-126-U-S2 we have developed no less than three units with identical functions but different fieldbus interfaces to make even demanding synchronisation applications easily manageable. The ideal device technology for presses, motion drives and all other applications where power and precision are important.

The UHC-126…S2 features a distributed synchronisation system, a new and very robust approach. The patented MR controller linearises the controlled systems and completely eliminates interactions between the individual axis control loops.

Furthermore, the solution enables a theoretically unlimited number of synchronised axes and a high accuracy of the position measurement due to the possibility of connecting SSI sensors; alternatively, an analogue sensor interface is available. There is also the option of a superseding pressure control, in which the effective force of the cylinders can also be controlled. In addition, driver modules for Simatic PLCs are available for simple and fast integration into the machine control system.

Automatically the right pressure for your press

The tried and tested made even better: MDR-337-P with commissioning assistant

Our MDR-137-P module has been tried and tested for years for pressure control in combination with proportional pressure valves or variable pumps and has been extremely successful. Now with the new MDR-337-P we can once again present a clear upgrade of the concept. New in this module is the function for characteristic-based pilot control and the commissioning assistant, which perfectly matches the pilot control to your application and also performs the controller optimization automatically.

For you as a user, this has tangible advantages:

You benefit from a really exact linearization …
… but have no additional effort!

You save the time that you would otherwise invest in setting the controller parameters …
… but have an excellent result immediately!

W.E.St. Elektronik GmbH – setup for future!

20 years after founding the W.E.St. Elektronik GmbH, Mr Ulrich Walter has decided to begin his well derserved retirement and to sell the company to new owners. This step has been very carefully prepared over the last months with the new owners, namely Thomas Helpenstein and the Swedex Holding GmbH. Based on that, we would also like to announce that Thomas Helpenstein will be named managing director of W.E.St. Elektronik GmbH, effective October 1st, 2019.

The Swedex Holding GmbH has established its market presence by the Swepro group for more than 30 years, as a specialized supplier of innovative and sophisticated pneumatic solutions including industrial tools and the broadest offering of air nozzles, complemented by electrostatic solutions. The Swepro group currently employees over 100 people in 13 countries globally.

Thomas Helpenstein has made his career in developing and marketing of industrial control device. He has held positions in engineering, product management and business management with global responsibility for a wide range of industrial components used for machinery automation and functional safety for machinery.

Affiliating with a solid corporate business offers a wide range of opportunities for collaboration and to leverage each other’s competencies and resources. With this and together with Thomas Helpenstein‘s broad experience we strongly believe that the W.E.St. Elektronik GmbH is very well prepared to foster our key competencies, evolve products and technologies and expand their distribution in future.

We will continue to focus on developing and expanding our offering of electronic control modules for hydraulic applications, especially complementing this offering by network based components to provide a contemporary solution for your hydraulic system with seamless integration with superior controls (PLC).

Customer loyalty and a close relationship has been and will be a key value for us. Therefore, the team and location of W.E.St. Elektronik GmbH will remain as is so that nothing changes for you! Please use the same contacts as usual and place your orders via email, fax or phone etc. as before.

Finally, we would like to thank Elke Walter and Ulrich Walter for the the last 20 years and wish all the best for their retirement!
