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.
W.E.St. Elektronik GmbH has enhanced its intuittive configuration software to ease and accelerate start-up and diagnostics procedures even more. Generally software based solutions haven become an essential tool complementing screw drivers and voltmeters to reduce downtown during commissioning and maintenance phases. With WPC-300 I/O Data as well as target values can litterly be caught at the same time, together with oscilloscope showing and recrding live values. The software is compatible with all previpous and current versione of our products. So no trouble to find the compatible version to connect to an installed device. Download WPC
We have recently renewed the GL certification of PAM-199-P to comply with the latest requirements of contemporary marine applications in shipping and in offshore segments. The power amplifier is typically applied for control of directional, throttle and pressure valves, which require flexible adaptation. The integrated power amplifier with a short cycle time of 0,125 ms for the current loop is an inexpensive and space-saving solution. Its versatility allows to control typical proportional valves from various manufacturers with a minimum of commissioning effort.

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!

The Spinner company consistently relied on I/O-Link when designing the MICROTURN series. A coherent wiring and shielding concept made the decision for I/O-Link easy for the medium-sized machine manufacturer. Especially in connection with the Spinner Touch surface “SPIOS” a perfect commissioning and diagnostic tool was created. All actuators/sensors can be parameterized and analyzed with the aid of the surface. In line with Industry 4.0, a complete database for signal exchange was created here. The I/O-Link valve amplifier from W.E.St. Elektronik enables the operator to optimally adjust the clamping pressure of the chuck to the clamping requirement. This is done comfortably via the user interface, but the pressure can also be “reprogrammed” variably by the NC program. The compact design of the valve amplifier and simple integration into the I/O-Link platform spoke in favor of the W.E.St. Elektronik.

This electronic module for position and pressure control is controllable via the Profinet/Profibus/EtherCAT interface and it can be integrated in the existing control system simply and quickly. Function blocs for the PLC S7 are available. The position controller was revised in order to fulfill special requirements. Best dynamics and highest position accuracy are the result of this development.
Technical Data: UHC-126-U
In addition to the standard positioning, the following options are implemented:
- Direct control, at any time the command position can be changed via fieldbus
- Rapid/creep speed for automatic drive of predefined profiles
- Drift compensation for a correct zero-point adjustment, controllable via fieldbus
- Accurate positioning to compensate positioning deviations caused by external forces
- Stroke dependent deceleration or NC control
- P or PT1 position controller, for stable and dynamic positioning
- Acceleration feedback for stabilization of critically controlled axes
- MR-Control function to linearize the hydraulic axis. An absolute linear behaviour, controlled by the robust MR function can be activated.
- Simplified and intuitive parameterization
Additionally, a PQ pressure control function can be activated (with or without position control). In PQ mode, typically both pressures will be measured to build the differential pressure.
- optimized PID controller
- a dynamic integrator can be activated to minimize pressure overshoots
- two switchable PID parameter sets
The interface to the PLC is a Profinet interface. In view of Industry 4.0, all command values and all feedback (process data) are available in the protocol. Parameterization of the module via the bus is also possible.
IO-Link, a universal and cost effective interface to control hydraulic valves (control valves and proportional valves).
Available! The IO LInk plug amplifier for proportional valves. The IO Link interface allows a seamless integration with the rest of your control solution and hences reduces to overall engineering effort to maintain various implementaion across the application. We will continue to expand the connectivity via IO Link. Next in line will be the amplifier version for control valves.
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.
