b)  Shifting the positioning range upwards starting from the delivery state 

In the following example, starting from the DS, the maximum possible positioning range is shifted 
slightly 

upwards

 

using the parameter “upper mapping end” (example for a PSD401/411, 

PSD422/432 or PSD480/490): 

 

Here, the upper mapping end was increased from the value 806,400 to 1,031,600. Consequently, 
a higher proportion of the possible positioning range is in the positive range and a smaller 
proportion in the negative range. 

In the extreme case, the upper mapping end can be set so that the entire possible positioning 
range is a

t values ≥ 0. With standard scaling (numerator = denominator = 400, i.e. 1 step = 0.9°) 

and referencing value = 0, this special case results if the relevant value from the following table is 
selected for the upper mapping end. The device then automatically adjusts the lower and upper 
limits accordingly.
