FluidPower Axis

A hydraulic axis can be designed as either a valve-controlled or a pump-controlled drive. To solve this, a special configuration of the standard axis is used in the MC3. The hydraulic axis can operate with several types of position measuring systems and actuators.

Adding a hydraulic axis works on the same principle as a standard electric axis:

• Adding an axis

In general, the FluidPower axis is capable of controlling both the position and the force or pressure of the hydraulic axis. The block diagrams and a supplementary description for each control system can be found here:

• Position controller
• Pressure/force controller

Force and pressure control requires the integration of pressure and force sensors. Details can be found in the following section:

• Pressure sensor A/B
• Virtual force sensor

What makes the solution integrated into MC3 unique is the ability to implement and automatically record the system characteristic curve. This is connected downstream of the position or force/pressure controller, thereby eliminating the system's nonlinear properties. Details on the system characteristic curve can be found in the following section:

• Valve characteristics

The FluidPower axis also has several properties and parameters that are unique to this model and not found on the standard axis:

• Axis parameters
