Hydraulically controlled drives are normally configured by the technical sales
and marketing personnel of the hydraulics supplier (e.g. Bosch
Rexroth, see Chapter 8) in close co-operation with the machine manufacturer.
This configuring phase is divided into the following steps:
S
Selection of the cylinder on the basis of forces and velocities required and
the cylinder mounting conditions in the machine
(see Subsection 2.3.1).
S
Selection of the servo solenoid valves on the basis of the cylinder data,
forces, velocities and dynamic requirements (see Subsection 2.3.2, 2.3.3).
S
Selection of the position measuring system and optionally the pressure sen-
sors with regard to the measuring range, accuracy and linearity (see Section
7.1, 7.3).
S
Dimensioning of the hydraulic power unit, taking all loads into account (see
Subsection 2.3.5).
S
Calculation of the natural frequency of the drive for an initial assessment of
whether the expected control result can be achieved (see Subsection 2.3.4).
S
In difficult cases, it may be worthwhile carrying out a dynamic simulation of
the drive as an aid to configuration.
The basic data required to design a system are obtained from a question-
naire.
