A methodology for generating a motion profile for an axis of a motor in a mailing apparatus, the linear or angular motion of the motor axis imparting a motion to a sheet or envelope being conveyed by the mailing apparatus. The methodology includes four processes for generating a segment of a motion profile, depending on whether, for the segment, absolute positional synchronism (of the motor axis to be controlled relative to another motor axis) is needed, or whether a so-called quick step is needed, i.e. a change in velocity corresponding to acceleration that varies during the step. The processes include: forward integration, given the jerk (acceleration per unit time) and starting acceleration as well as initial values of position and velocity; non-parabolic displacement mapping (sometimes called electronic gearing) relating the motion of the axis to be controlled to the motion of another axis where the function expressing the mapping is not parabolic in the commanded or actual position of the other axis; integration based on a velocity equation that is parabolic in time; and a parabolic displacement mapping, i.e. a displacement mapping using a function that is parabolic in the actual or commanded position of a reference axis.
