Waiting period
Period of time, which must at least be maintained by a step of a program regardless of process feedbacks (DIN 19 237).
Spherical cone
Pump piston with a spherical piston surface, which contains piston rings for sealing. The piston shaft is lowered ( Figure S 75 ). The spherical piston is used in axial piston machines, in which the c
Pulse code modulation
Process for converting analogue signals to digital signals . Sampling will convert a signal that is continuous over time into a series of impulses. The transfer does not take the form of impulses of d
Steady state
The steady state of an element is the state to be maintained for a period as long as necessary that results from input signals that are constant over time, after all settling processes have ended (DIN
Axial gap compensation on gear pumps (so-called gap compensation)
Gear pumps have two sliding-contact areas (sealing areas): at the periphery as well as the two sides of the gear wheels, i.e. in the axial direction. The pressure-controlled leakage that occurs here c
Settling time T g
The time after a step change in the correcting variable defined by the intersections between the first inflection tangent and the abscissa, and the line parallel to the abscissa through the value in t
Minimum control flow
Flow rate that the source controlling an element must provide to control the element reliably.
Interfacing controller
Control used to interface a numerical control to the machine tool. It e.g. Converts and amplifies the signals that are exchanged between the numerical control and the machine tool, provides Logical op
Analogue computer
The analogue computer represents the problem to be solved as analogue physical variables, e.g. as lengths, resistances among others; the problem as a whole is represented here. Analogue computers are
Addressing modes
Different possible ways of accessing registers and memory in the instruction set for a microcomputer. Such possible ways can be: implicit, absolute, indirect, relative etc.
