6.3.16 Inverting Output
Conditions
do.17...do.24
With parameter do.17...do.24 each of the four switching conditions (do.1...do.4)
can be inverted separately for each output. Through this function any switching
condition can be set as Non-condition. The parameter is bit-coded. According to
picture 6.3.16 the weighting, for the switching condition to be inverted, is to be
entered in do.17...do.24. If several conditions are to be inverted, add up the values.
Output Out3 shall be set, when the inverter does not accelerate! In this case we
put switching condition 15 (inverter accelerates) e.g. on do.1 (enter value 15). With
do.19 we invert the switching condition do.1, therefore enter value 1.
6.3.17 Selection Output
Conditions
(do.9...do.16)
Example:
The parameters do.9...do.19 serve for the selection of the previously defined
switching condition. The selection is done separately for each output. You can choose
between no condition up to all 4 switching conditions. According to picture 6.3.16
the weighting of the selected switching condition is to be entered in do.9...do.16. If
several conditions shall be selected, add up the values.
After the switching conditions are selected for each output, it can now be specified
how these are to be linked. As a standard all conditions are OR-linked, i.e. if one of
the selected conditions is met, the output is set. As another possibility an AND-
function is available, which can be adjusted with do.25. AND-function means that
all selected conditions must be met, before the output is set.
Parameter do.25 is bit-coded. The table of 6.3.19 shows the assignment.
