Continuation „Mode Frequency“:
AVERAGE FILTER 2
Selectable averaging or filter function for unstable frequencies at input A for smoothing the analog signal. At
settings 5 to 16, the device uses an exponential function.
The time constant T (63%) corresponds to the sampling cycles.
For example: If SAMPLING TIME = 0,1 s and AVERAGE FILTER = Exponential filter, T (63 %) = 2x SAMPLING
TIME, after 0,2 seconds, 63% of the step size are reached.
0
No average value will be created (quick reaction to every change)
1
2 numbers of floating average cycles
2
4 numbers of floating average cycles
3
8 numbers of floating average cycles
4
16 numbers of floating average cycles
5
Exponential filter, T (63 %) = 2x SAMPLING TIME
6
Exponential filter, T (63 %) = 4x SAMPLING TIME
7
Exponential filter, T (63 %) = 8x SAMPLING TIME
8
Exponential filter, T (63 %) = 16x SAMPLING TIME
9
Exponential filter, T (63 %) = 32x SAMPLING TIME
10
Exponential filter, T (63 %) = 64x SAMPLING TIME
11
Exponential filter, T (63 %) = 128x SAMPLING TIME
12
Exponential filter, T (63 %) = 256x SAMPLING TIME
13
Exponential filter, T (63 %) = 512x SAMPLING TIME
14
Exponential filter, T (63 %) = 1024x SAMPLING TIME
15
Exponential filter, T (63 %) = 2048x SAMPLING TIME
16
Exponential filter, T (63 %) = 4096x SAMPLING TIME (very slow reaction)
Notice:
When using the exponential filter, the maximum permissible frequencies at the input must
not be exceeded due to an otherwise following data type overflow!
If the frequency is nevertheless exceeded, the frequency is replaced by the maximum
permissible value (with corresponding setting) for further calculation and an error is output.
The LED flashes and the analogue output consequently controls 0 V or 0/4 mA.
The maximum permissible frequencies have already been listed in parameter AVERAGE
FILTER 1 and can be taken there.
