The following characteristic is set by default and can be adapted to the application via the
parameters mentioned.
Point 1:
V0,20 V102,00%X1 
Hz 0,00Hz 50,000,00%Y1 
Point 2:

The freely configurable characteristic enables setting a tolerance at the ends as well as a reversal of
the direction of rotation.
The following example shows the inverse reference value specification with additional reversal of the
direction of rotation. This is often used in pressure control systems.

The change of direction of rotation is done in this
example at an analog input signal of 5.5 V. pos./neg.
maximum figure
The definition of the analog input characteristic can be calculated via the two-point form of the line
equation. The speed Y of the drive is controlled according to the analog control signal X.
