100944 Range Control 2
Description
The block performs range control.
The value of the parameter entered in
D70 is read, multiplied by D71 and filtered with
the time constant D72 by a low pass. The result is written to D79 and transferred to
range control.
Range control checks to determine in which of the five following ranges the value is
located and switches one of the five outputs to
1:active . If the limits are correctly
specified ( D74 < D75 < D76 < D77 ), the following reactions occur.
D79 > D77 is 1:active
D76 < D79 ≤ D77 is 1:active
D75 ≤ D79 ≤ D76 Ar2GRN is 1:active
D74 ≤ D79 < D75 Ar2YEL- is 1:active
D79 < D74 Ar2RED- is 1:active
The sequence of the check is shown by the numbering below. In particular this
specifies the reactions of the block when the inputs are not sorted as per
D74 < D75 < D76 < D77 .
1 D79 > D77 , D199 is 1:active
2 D79 > D76 , D198 is 1:active
3 D79 < D75 AreaRED-, D197 is 1:active
4 D79 < D74 AreaYEL-, D196 is 1:active
5 Otherwise: AreaGRN , D195 is 1:active
Parameter
D73 can be used to enable the creation of an absolute value.
Range control can be disabled by the signal on the input Reset .
Range control can also be disabled based on parameter D78 . When D78 is set to
0:inactive , range control is disabled when A900 = 0:inactive or one of the signals on
AccActiv or DecActiv is active. This can be used, for example, to disable range
control during accelerating or decelerating procedures. When D78 is set to 1:active ,
range control is always calculated.
