14.1.115.3 Calculation of the output signal
The output value at dnOut_p can be detected according to the following formula:
Example
You want to determine the counter content of the integrator at a certain speed at the input
and a certain integration time t.
Given values:
nIn_v = 1000 rpm ≈ integer value 1092
Integration time t = 10 s
Starting value of the integrator = 0
Solution:
Conversion of the input signal at nIn_v:
Calculation of the output value:
t = integration time
16384 ≡ 15000 rpm
1 ≡ 1 incr.
