Abstract
A more accurate tension of a belt or a more accurate target natural frequency of the belt when the belt tension is adjusted is determined. A method for calculating a belt tension includes receiving a natural frequency of a belt and a span; performing calculation for determining a tension of the belt using a predetermined expression, based on the natural frequency, the span, and a unit mass of the belt read from a memory; and displaying the tension on a display, wherein in a case where the span is within a predetermined range corresponding to the belt, the predetermined expression is corrected so that an error caused by a bending stiffness of the belt is reduced.
