Two-point controller
Non-continuous controller with two switching positions. The output signal can only take on 2 different values (neglecting the switching processes). Multi-position controller
Control range
Range within which the control variable can be configured, considering agreed values of disturbance variables, without jeopardising the functionality of the (DIN 19 226).
Addressing modes
ways of accessing registers and memory in the instruction set for a microcomputer. Such possible ways can be: implicit, absolute, indirect, relative etc.
Primary noise control
All measures which a manufacturer of hydraulic pumps can take to keep the amount of noise generated as low as possible. Alternative: secondary noise reduction measures
Detent
Moving parts of devices are fixed in one or more positions by a detent and can be moved to another position given an increased shifting force.
Timing control
Control in which the reference variable (n) is delivered by a time-dependent programmer . The programmer can be started by a trigger signal (DIN 19 226).
System-compatible signal
Signal whose are defined for an equipment group (modular system) and which can be processed by all devices of that group without additional measures (DIN 19 237).
Continuously adjustable valves
for valves such as proportional valves , high response proportional valves and servo valves, which can be continuously adjusted .
Error curve of measuring instruments
Graphic representation of the error as a function of the output (indication). The error behaviour can also be defined in a table (Figure F 5) (VDI 2600).
control parameters
Setting values of the controller, which can be used to adapt the controller properties to the conditions of the controlled subsystem, and the quality requirements of the .
