5.4 Factor Reference Value (Weighting)
Information that you will find in
this section …
This section shows you how to weight one of the combinations described in chapter 5.1,
5.2, or 5.3 with a factor.
Weighting with the factor
reference value
To set up weighting proceed as shown below:
• Set one of the combinations described in chap. 5.1, 5.2 or 5.3.
• Select a reference value source in D33 (e.g., "5:correction ref 2").
The reference value is related to D56 and multiplied by the result of the addition of main
reference value and additive reference value (see Figure 5-5).
Example:
The sum of main reference value and additive reference value results in the value 1500
rpm (D382). 3000 rpm is entered in D56. The reference value selected in D33 has the
value 1000 rpm.
The result is calculated as follows:
1500 rpm x 1000 rpm / 3000 rpm = 1500 rpm x 1/3 = 500 rpm
This value is indicated in D383.
