The figure below shows the function of the lo and hi lim parameters. The input voltage, after the offset and gain
compensation, supplies on the output a linear value included between lo lim and hi lim. The two parameters can
assume any value with the restriction of:
lo lim lower than hi lim

it is important to remember that the hardware configuration on the regulation card has to be
set according to the selected input.

Hi lim
-10V...+10V
input connects a signal with a maximum voltage of +/-10V.
The change in the motor rotation direction is obtained according to the signal polarity.
Input voltage > 10V or >-10V cause saturation of the count value.
on the input it is possible to connect a maximum voltage of +10V or a 0...20mA current signal.
The signal must always have a positive sign, through which, if used as a reference, it
is possible to change the motor rotation direction via AI 1 sgn src.
