0 - Off
1 - +/- reference value
2 - Positive only
3 - Inverted
The inversion of the reference percentage by means of signal start-anticlockwise or operator panel is

Via digital logic signals or digital inputs fixed preset reference values can be selected.
The fixed percentages define reference values. Four fixed percentages can be set. The fixed percent-

Via the reference percentage channel (see chapter 7.5.2 "Reference percentage channel"), the fixed
percentages can be selected and linked to other reference value sources. Linking is effected via pa-
