7.2.8.4 Object 0x6345: Threshold
This parameter defines the positions of the steps (<DeadbandCompensation_ASide> (0x6343) and <Dead-
bandCompensation_BSide> (0x6344)). This determines the starting point of the dead band compensation
step.

7.2.8.5 Jump function (dead band compensation type 1)
If the input signals keep within the limits of the threshold value (set with parameter <DeadbandCompensa-
tion_Threshold>, 0x6345), the output signal will be zero. At the threshold positions the output signal is in-
creased or decreased by the step height defined by the parameter <DeadbandCompensation_ASide>
(0x6343) or <DeadbandCompensation_BSide> (0x6344). The output signal is interpolated in the area be-
tween the threshold positions and 100 % of the input signal.
This dead band jump function is activated with the parameter <DeadbandCompensation_Type> (0x6342) set
to 1 (dead band jump function).

7.2.8.6 Continuous function (dead band compensation type 2)
If the input signals keep within the range of the threshold value (set with parameter <DeadbandCompensa-
tion_Threshold>, 0x6345), the output values will be interpolated between zero and the values defined by the
parameters <DeadbandCompensation_ASide> (0x6343) or <DeadbandCompensation_BSide> (0x6344), re-
spectively. At the threshold position the output signal is increased or decreased by the values set for the
<DeadbandCompensation_ASide> (0x6343) or <DeadbandCompensation_BSide> (0x6344). The output sig-
nal is interpolated in the area between the threshold limit and 100 % of the input signal.

This function serves to achieve a continuous transition between the areas that are within and out-
side of the threshold value.
