Ramp
adapt acceleration and delay processes to the respective requirements. The incline and decline ramps can be selected separately.
Energy conversion
Of the most important forms of energy that can be used for drives (mechanical, hydraulic and pneumatic) only mechanical energy does not require conversion (Figure E 29) . For all forms of energy the detour
Position/time diagram
cylinders in order to get an overview of the function sequence ( Figure W 9 ). This method of illustration can also take place in steps and is a preliminary stage before the function diagram .
Technical cybernetics
their internal transfer and processing of information, to show ways in which the respective system can be influenced in order to achieve certain objectives.
Identification of a system
ion of a controller are based. It acts like a kind of automated analysis of system parameters. It can take place within a time or frequency range.
Check valve
pressure on the barrier element. For certain applications, check valves are built so that the barrier can be lifted by control pressure ( releasable check valves).
Optical fibre technology
bus lines are increasingly being based on optical fibre technology. Optical fibres and power cables can be laid side by side. In general, information is split between three optical fibres. One possible benefit
Digital measured signal
(VDI/VDE 2600). The resolution of digital signals is limited by the selected step size that, however, can be very small. However, more time is then also required for the processing. Digital measured signals
Metallic seals
undergo plastic deformation, which enables them to fill up any surface roughness . This is why they can only provide a tight seal on non-moving surfaces. Soft metals (soft iron, copper, aluminium) are used
Gap seals
working medium determine the sealing performance. Given these framework conditions , sealing gaps can never be completely tight. On the other hand, it is beneficial that, as non-contact seals, they cause
