9.4 Description of parameters
The FLOW scale is the standardization from 0 to 100% in the range between the "YA" and
"YE" parameters. Over this range, the setpoint w is also always 0 to 100%. This results in a
more or less flow-proportional display and position feedback "I
display and position feedback "I
In order to calculate the control deviation, the setpoint in the display is also shown in the
corresponding scale.
The following uses the example of an 80-mm linear actuator to illustrate the dependence of
the stroke on the scaling as well as the parameters "YA" and "YE".
