The acceleration and deceleration curves can deviate from a straight line to a varying degree.
Parameters A131 and A132 control the amount of deviation for the acceleration and decelera-
tion curves respectively. The following graphs show intermediate output frequency points as a
percentage of the target frequency, for 25%, 50%, and 75% acceleration time intervals.
