Measures taken to change the velocity of a cylinder (motor) either by means of information from the circuit (e.g. pressure changes) or by means of information from the exterior. The velocity control i

Stress, which occurs where the moved surface runs against the sealing lip , i.e. the frictional force on the sealing surface and the compressive force are working in the same direction. The friction i

Time function which produces a general increase or decrease to a specified end value when moving and braking ( Figure R 9 ). As the ramp is equal to the integral of a step function over time, the time

Filter installed directly in the pipe using a thread or flange (see also flange mounted filter ).

Pre-load valve

The compression pressure of the air, which overlays the atmospheric pressure when the sound waves spreads. It is measured as an effective pressure in N/m2, but is stated in Decibels (dB) as a noise le

Electronic functional group to produce ramps. Its effect is based on the fact that an electrical condenser (C) is charged (and discharged) with a delay ( Figure R 10 ), resulting in a general voltage

Workflow control with step enabling conditions that are only dependent on signals from the controlled system (process) (DIN 19 237). The process-dependent workflow control – previously known as "seque

General : A part of a program which can be delimited in terms of its allotted task or structure. A control : Consequence associated with control instructions for a self-contained application-based fun

Refers to the shift, expressed as the angle φ, between two sinusoidal variables or signals with the same angular frequency ω such as the input and for a transfer element . The phase shift is described
