(Note 1) A linear characteristic will result (A097 = A098=00) if 0% is set for the curve ratio.
(Note 2) A linear characteristic will result if the change of the target speed is less than or equal
to 10% of the maximum frequency.
(Note 3) All of the curve constants are ignored if "04" is selected in A097 and A098. Refer to the
manual for standard S-curve acceleration & deceleration description.
(Note 4) The S-curve will be recalculated if the target speed is changed while accelerating or
decelerating. Therefore do not use analog signals for the target speed.
(Note 5) Curve ratio for acceleration/deceleration must be in the range of 10% up to 50%.
