1)
Filter off: 0 s; propagation times filter and A/D converter see table; The result is time for an
output signal of 50% of the full scale value with a jump at the input.
2)
These signals can also use other sources. The phase delays of the source signals must then
be added.
3)
If the analog output is to output a value from this group, you must add on 52 μs. If you are
using a source from a different group, you must add the phase delay of the source signal to
the 52 μs.
Abb. 36: Minimum phase delay for group 1: 52 μs plus A/D converter conversion time
plus filter phase delay
Some signals might also have sources from other groups. For example, the analog out-
put might deliver a signal from the ClipX bus. In these cases, you must add the propaga-
tion time of the source signal's group in order to get the total propagation time:
Example 1
Phase delay from input, e.g. 10 V, 20 mA or DC full/half bridge, to analog output (10 V)
with a Bessel filter at 1 kHz:
•
A/D converter (ADC) plus filter: 690 μs.
Added to this is a jitter of up to 52 μs, as the A/D converter is not synchronized with
group 1.
Group 1: 690 μs + 52 μs max.
•
Analog output: 52 μs.
So the total phase delay is 742 ... 794 μs.
