2.4.7.3 Calculation of the output signal
The output value at dnOut_p can be derived from the formula:
dnOut_p[inc] + nIn_v[rpm] @ t[s] @ 65536[incńrev.]
(t = integration time, 16384 15000 rpm, 1 incr. = 1)
Example:
You want to determine the count of the integrator with a certain speed at the input and a certain
integration time t.
Given values:
nIn_v = 1000 rpm (INT)1092
t = 10 s
Start value of the integrator is 0.
Solution:
Conversion of the input signal at nIn_v:
1000rpm +
1000rev.
