VPPX - Distribuitor de control si comanda
Features & Benefits
cascade Controller For a precise and stable pressure control
External feedback signal For best control result directly in the application For various sensors (pressure, flow, force, ...)
programmable With FCT and a plug-in specially designed for VPPX
Program software With Oscilloscope function to control optimization All control related parameters set

Application force control

In this application, the goal is to generate a constant force, and to eliminate a disturbance occurring
You operate the VPPX in a open loop operation without an external sensor. What happens when the error in the form of a counter-pressure at the bearing cap side occurs. Where it plays an important role in practice?
you take now the VPPX with external force sensor in operation Configure the sensor accordingly and try by yourself by using the Oszifunktion the best controller settings. How does one override the disturbance variable from now?

W 1. The set point is entered via a PLC
or set point generator.
2. The force control may be direct or
inverted.
3. Direct: The cylinder applies a force
directly on the force sensor. The set
point has a power-enhancing. (0V
↔ 0kN)
4. Inverted: A predetermined force
which is applied to the sensor is
reduced. (0V ↔ 0kN)
5. A load change is corrected
immediately

Application pressure control
• The set point is entered via a PLC or set point adjuster.
• Through the use of a choke between VPPX and the volume of the VPPX adjusted to a higher pressure level, thus a better control performance is achieved.
• With the device connected to the volume pressure sensor 0 ... 0.1 bar the feedback signal of the sensor is directly attributed to the VPPX
