Method for adjusting a range of numerical values at an input device for configuration or selection of components of an electrical drive system with regard to a parameter as numerical value, wherein the input device has a display on which a strip of numerical values is displayed, on which strip a minimum value for the numerical value and a maximum value for the numerical value are displayed variably, the minimum value and the maximum value form between themselves a range of numerical values, the method comprising the steps of: - displaying a minimum-value slider as graphical element and displaying a maximum-value slider as graphical element with a distance therefrom, which graphical elements are movable in each case for changing the range of numerical values, - moving the minimum-value slider toward the maximum-value slider or away from it and/or moving the maximum-value slider toward the minimum-value slider or away from it, - reducing the minimum value in the case of moving the minimum-value slider away from the maximum-value slider and enlarging the minimum value in the case of moving the minimum-value slider toward the maximum-value slider in order to obtain a new minimum value, - reducing the maximum value in the case of moving the maximum-value slider toward the minimum-value slider and enlarging the maximum value in the case of moving the maximum-value slider away from the minimum-value slider in order to obtain a new maximum value, - changing the range of numerical values by spanning a new range of numerical values with the new minimum value and/or the new maximum value, wherein, when moving the minimum-value slider or the maximum-value slider toward one another, the range of numerical values is reduced and wherein, when moving the minimum-value slider or the maximum-value slider away from one another, the range of numerical values is enlarged, characterized in that the minimum-value slider or the maximum-value slider return to a new location on the strip of numerical values up to shortly before their original location after being moved and released so that the new spacing between the sliders (13, 16) is between 60 % and 99 % of an original spacing between the sliders (13, 16). - displaying a minimum-value slider as graphical element and displaying a maximum-value slider as graphical element with a distance therefrom, which graphical elements are movable in each case for changing the range of numerical values, - moving the minimum-value slider toward the maximum-value slider or away from it and/or moving the maximum-value slider toward the minimum-value slider or away from it, - reducing the minimum value in the case of moving the minimum-value slider away from the maximum-value slider and enlarging the minimum value in the case of moving the minimum-value slider toward the maximum-value slider in order to obtain a new minimum value, - reducing the maximum value in the case of moving the maximum-value slider toward the minimum-value slider and enlarging the maximum value in the case of moving the maximum-value slider away from the minimum-value slider in order to obtain a new maximum value, - changing the range of numerical values by spanning a new range of numerical values with the new minimum value and/or the new maximum value, wherein, when moving the minimum-value slider or the maximum-value slider toward one another, the range of numerical values is reduced and wherein, when moving the minimum-value slider or the maximum-value slider away from one another, the range of numerical values is enlarged, characterized in that the minimum-value slider or the maximum-value slider return to a new location on the strip of numerical values up to shortly before their original location after being moved and released so that the new spacing between the sliders (13, 16) is between 60 % and 99 % of an original spacing between the sliders (13, 16).
