Parameter assignment
5.11 Parameterizing analog output AQ via the High Feature 3RW5 HMI
Factor for calculating the output measured value
Measured value
Phase current average (%)
Example for calculating the parameters for the range start value and range end value
In this example, a pointer instrument indicates the measured value "Phase current average
(%)" at the left stop with 50 % (start value) and the right stop with 200 % (end value). You
can divide the scale of the pointer instrument between the left stop and the right stop,
depending on the desired resolution.
The following parameters are given as examples at this point:
● Output signal type: 4 ... 20 mA
● Range start value = desired start value (%) / factor of the measured value
● Range end value = desired end value (%) / factor of the measured value
Procedure
1. Parameterize the output signal type, e.g. 4 ... 20 mA.
2. Parameterize the range start value and the range end value taking the following factor
into account:
– Range start value (50 % / 3.125 %) → 16
– Range end value (e.g. 200 % / 3.125 %) → 64
Result
You have adjusted the output signal of the analog output.
