A particularly cost-effective and precise axis control, flexible additional functions and quick and easy commissioning – all this is offered by our new POS-321-P module.

In addition to the well-known function of the commissioning assistant, the script language based on the “FlexiMod” concept was integrated into this unit. This means that the function of the device can be easily adapted to the requirements of a wide variety of applications without external control functions.
The implementation of oscillating controls, parameter switching, own monitoring functions, etc. is extremely easy, programming knowledge is not necessary.

A particular advantage is that the basic function of axis positioning is already available in the delivery condition. This function can be adapted and extended by the script.

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.

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.

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!
