current) generates, via the magnetic field in a coil, a mechanical (distance or force). Solenoids can be designed either as linear solenoids (switching solenoid), as proportional solenoids or as control
Stiffness of actuators
annular area: with A K = piston surface area. Cylinders with a large active area and small stroke can be very stiff. In the case of high pressures and strokes, however, they are softer. Stiffness is therefore
Test conditions
deviation. Under repeat conditions, the same systematic deviations occur with each measurement. They can therefore not be defined outside of the repeat measurement series. Conditions of comparison : are present
Overlap in valves
longer than the ring nut. When switching, the overlap must first be passed through before a flow rate can flow ( Figure U 1 a ). Negative overlap : The piston is shorter than the ring nut. In rest position
Electro-mechanical signal converters
rotational speed corresponds to the pulse frequency. The low power of stepper motors (approx. 100 W) can be hydraulically amplified in electro-hydraulic linear or torque amplifiers. The result is simple but

Loading models for cylinders
pressure fluctuations : Approximately constant pulsation width; superimposed pressure oscillations can rise to 30 bar above p N. Calculation: static against deformation and overload fracture as well as

Transmission method
traffic . The advantage of a data connection with full duplex operation is that the data transfer can take place in both directions.

specific case is generally implicitly stated by a set of relationships (e.g. differential equations) and can be determined through measurements, system analyses, laws of nature, amongst others (according to DIN
