Unipolar and bipolar measuring ranges
The figure below shows the scaling for an actuator that is to be addressed at a program
value of 0% with the minimum value 0 (0 V or 0 mA) and at 100% (+27648) with the
maximum value (10 V or 20 mA).
Figure 2-9 Unipolar measuring range
The figure below shows the scaling for an actuator that is to be addressed at a program
value of 0% (-27648) with the minimum value 0 (-10 V or -20 mA) and at 100% (+27648) with
the maximum value (+10 V or +20 mA).
