Illustration of this extreme case for a PSD401/411, PSD422/432 or PSD480/490:
Note:
The numerator factor and denominator factor can be used to map any spindle
resolutions. Using the referencing value, you can shift the whole range of values.
c) Shifting the positioning range downwards starting from the delivery state
In the following example, starting from the DS, the maximum possible positioning range is shifted
slightly
downwards
using the parameter “upper mapping end” (example for a PSD401/411,
PSD422/432 or PSD480/490):
Here, the upper mapping end was decreased from the value 806,400 to 581,200. Consequently, a
higher proportion of the possible positioning range is in the negative range and a smaller
proportion in the positive range.
In the extreme case, the upper mapping end can be set so that the entire possible positioning
range is
at 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.
