Minimum torque on the motor shaft of a hydraulic motor on starting from standstill. Above all the friction conditions during starting from rest (stiction) and at low speeds influence this parameter.

Characteristic of analogue signal processing is the predominant usage of progressive function blocks for processing analogue signals. It requires, at least during the control of continuous processes,

Visual display in numbers, letters and special characters. Compared to the analogue display it reduces reading errors, but does not allow trends to be detected. Alphanumeric displays include the LED d

Double-acting cylinder with one-sided piston rod in which the ratio of the piston area AK to the annular area on the piston rod side is essential for the function of the fluid-related circuit (CETOP R

Measuring system in which all position (or angle) information is referred to a common zero point. Every point on the measured path is identified by a unique signal. Measuring systems that can be used:

Time that elapses on the reduction of a variable from a defined upper value to a defined lower value.

Resistance, which a fluid subject to friction must overcome when flowing through and valves . It is noticeable in the form of a pressure drop ( pressure loss ). The flow resistance comprises frictiona

The displacement volume taken on by a hydraulic motor during a revolution ( set geometric displacement ). It may be constant or variable, depending on the motor construction type.

Procedure that compares the output of a system with the results from the calculation in a model of this system and that sounds an alarm if deviations are excessive.

Actuation of the adjustment equipment in a pump/ motor by an electric motor. Permits in general adjustment speeds that are not very high. Mostly slower than electro-hydraulic adjustment.
