Hydrostatic servo drive
Collective term for hydraulic cylinders and hydraulic motors . Given the low losses associated with the drive, both have very low levels of damping (D H = 0.05 to 0.2).
Time-based workflow control
Workflow control whose switching conditions depend only on time. For example, timer elements, time counters, gear shift drums with a constant rotation speed can be used to produce the switching condit
Programming
Covers the activities associated with devising, coding and testing a computer program (EDIN 19 226, Part 5). In a narrower sense therefore, the word describes the creation of a detailed algorithm in a
Force feedback
Here, the associated force is fed back to acknowledge that a state has been achieved. Force feedback generally uses mechanical means with the help of springs. Example: mechanical feedback from servo v
State equations
If the alignment of the output variables to the input variables in a transfer element is described by a system of differential equations or differential equations and standard equations, by introducin
Elbow fitting
Fitting , which forms an angle of normally 90° between the connection openings. It is offered as a pipe or screw-in fitting ( pipe screw connections ).
Transmission speed
The number of binary signals transferred over a data channel per unit of time (DIN 19 226 Part 5). At a cycle frequency of 1 kHz, in the case of series data transmission, this results in a transfer of
Flow machines
Collective term for pumps and devices, which work according to the hydrodynamic principle, i.e. in which the velocity element of the flowing fluid is decisive. For pumps, these are the centrifugal pum
Control instruction
The smallest independent unit of a program, which illustrates the work instruction.
Gap extrusion
Property of an elastomer seal to become squeezed behind the seal under the influence of pressure in the sliding gap, causing damage to the seal ( Figure S 65 ). Remedy: Another material back ring made
