4.17 Editing the valve characteristic
Meaning of the parameters
To obtain information on the characteristic diagram, press the "Characteristic information"
softkey.
Note
Manual entries are only required in exceptional cases
This data is automatically determined from the measurement. It is only necessary to
manually intervene here if the complete range was not measured and if the automatic
extrapolation of the characteristic does not satisfy the particular requirements.
● Zero range
Enter the coordinates of the transition point of the valve characteristic in the zero range.
Parameter: +Q = p1833 / +U = p1834, -Q = p1836 / -U = p1837, +rnd = p1835 / -rnd =
p1838
● Fine control range
Enter the coordinates of the transition point of the valve characteristic in the fine control
range.
Parameter: +Q = p1839 / +U = p1840, -Q = p1842 / -U = p1843, +rnd = p1841 / -rnd =
p1844
● Saturation range
Enter the coordinates of the start of the parabolic saturation range of the valve
characteristic.
Parameter: +Q = p1845 / +U = p1846, -Q = p1847 / -U = p1848
● Controlled system gain
Enter the controlled system gain of the velocity controller here. The controlled system
gain specifies the drive velocity (after transition compensation) at 1 V.
Parameter: p1475
● Plane adaptation
Here, enter the differences of the maximum velocities (dependent on the direction of the
velocity).
Parameter: p1830/p1831
● Velocity limit
The maximum velocity in the positive and negative direction is displayed here. You
cannot change these values.
