Arithmetic logic unit
Computer subsystem that undertakes the mathematical operations of a digital system . The ALU is the "heart" of the microprocessor. It operates between the registers and the control unit. For this purp
Pre-charge container
Low-pressure accumulator (3 to 6 bar) to create a traverse speed in the case of large cylinders, for which there is no more pump for rapid traverse . The pre-charge container is refilled with the refl
Synchronous control
Control , in which the signal action is synchronised with a clock signal (DIN 19 237). The clock signal comes from a clock device (clock, clock amplifier). This means that changes to the input signals
Parallel connection
Assembly option for hydraulic valves whereby the required valves for a function — e.g. directional valve, flow valves , high response proportional valves are assembled on top of each other on a base p
Speed ratio
The speed ratio of a hydrostatic transmission is defined by the ratio of the pump speed n 1 to the motor speed n 2:
Operating mode of a control
Characterisation of the nature and scope of the intervention in a control system by the operator and by feedback from the system to be controlled. Here in accordance with DIN 19 237 a differentiation
Pressure losses due to throttles
Sum of all the pressure losses that occur at the various throttling points in a system (i.e. wherever there is a cross-section constriction). Another type of throttle loss occurs if in a system with c
Setting pulse
Electrical impulse, which brings the storage elements of a system to the initial position (DIN 19 237).
Friction
The resistance that opposes the relative movement of surfaces in contact with one another. Friction is the main cause of the unwanted conversion of mechanical energy into heat and therefore energy los
