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

11

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
