Note:
The ADC-linear characteristic is described by 4 coordinates, based on a two-point equation:
0757P0759P
0758P0760P
P0757-x
P0758-y

For calculations the point-gradient form (offset and gradient) is more advantageous:
0

The transformation between these two forms is given by:

For scaling of the input the value of y_max and x_min has to be determined. This is done by the following
equations:

Dependency:
Affects P2000 to P2003 (reference frequency, voltage, current or torque) depending on which setpoint is to
be generated.
