Frequency window

This is the minimum time over which the frequency is
determined. Default 10 ms [resolution: 1 µs]
The number of pulses in the time the follow-
ing is measured. The maximum waiting time is speci-
fied in the "Frequency Wait Time" parameter. The
number of pulses is divided by the actual time window
size. The determined frequency is output in index
0x6010:13 [
}
142]
and as a process data.
The frequency calculation is carried out locally without
distributed clocks function.

Frequency scaling

Scaling of the frequency measurement (must be di-
vided by this value to obtain the unit in Hz):

Period scaling [

Resolution of the period in the process data:
100: “100 ns” period value is a multiple of 100 ns

Period resolution
[

Internal resolution of the period measurement:
100: “100 ns” period value is a multiple of 100 ns
The period is calculated internally with a resolution of
100 ns. The max. measurable period can then be ap-
prox. 1.6 seconds.
500: “500 ns” period value is a multiple of 500 ns
Internally the period is calculated with 500 ns resolu-
tion. The maximum measurable period is approx.
32.7 ms. The resolution of process data continues to
be the value according to index
0x8010:14 [

(e.g.
100 ns [default]).

Frequency Wait Time
[

132]
Waiting time [ms] for frequency measurement
Once the time specified in the
frequency window
[
}

has elapsed, the system waits for the next posi-
tive edge from track A. This enables the update speed
for the Frequency process data to be optimized, de-
pending on the expected frequencies. At least double
the period of the minimum frequency to be measured
should be entered here. t >= 2* (1 / f
