Functions
7.9 3RW5 HMI High Feature
Procedure
Parameters
Output signal type
Range start value
Range end value
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
The following measured values and parameters are given as an example:
● Output signal type: 4 ... 20 mA
● Measured value: Phase current average (%)
● Range start value = desired start value (e.g. 50%) / factor of the measured value
● Range end value = desired end value (e.g. 200%) / 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 (e.g. 50% / 3.125%) → 16
– Range end value (e.g. 200% / 3.125%) → 64
In this example, a pointer instrument indicates 50% (start value) at the left stop and 200%
(end value) at the right stop. You can divide the scale of the pointer instrument between the
left stop and the right stop, depending on the desired resolution.
Result
The output signal of the analog output has been adjusted.

Setting range
Deactivated
•
4 ... 20 mA (factory setting)
•
0 ... 10 V
•
0 (factory setting)
•
96 (factory setting)
•
Corresponds to 300% of the
average phase current (%).
Factor

Explanation
Via the "Output signal type" parameter you
can define with what type of signal the
analog value is to be output.
With parameters "Range start value" and
"Range end value" you can define which
value of the analog value to be output
corresponds to the lower output signal
value and in turn to the upper output signal
value.
Setting of the analog range,
•
e.g. 4 mA = 0
Setting of the analog range,
•
e.g. 20 mA = 96
