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 º 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.
60 s
– Calculation of the output signal
dnOut_p
+ 1000 rev.
60 s
@ 10 s @ 65536 inc
rev.
+ 10922666 inc
