A new addition to our family of hydraulic axis positioners is a module with an integrated power stage and Profinet interface. This combination enables the use of cost-effective and robust proportional valves without internal electronics. The Profinet interface allows seamless data exchange with the machine control system. Setpoints and actual values are transmitted digitally without any loss of accuracy. Extensive diagnostic information is available. The device can be fully parameterized either via the free WPC-300 software or directly through the Profinet interface. For this option, we provide a convenient function block for Simatic S7 controllers. This also makes it possible to store parameter sets in the PLC and automatically restore them during device replacement.
