• The S-shape acceleration/deceleration curve 2 when P.29=2
An acceleration slope is formed by combining P.7 and P.20. A deceleration slope is formed by
combining P.8 and P.20.
The target frequency increases and decreases as the acceleration and deceleration slopes presented
in the figure below. As shown in the figure below, adjusting the setting value of the inverter from f0
to f2 will result in S-shape acceleration with a time equal to P.7× (f2-f0)/P.20. On the other hand,
adjusting the setting value of the inverter from f2 to f3 will result in S-shape acceleration with a
time equal to P.7× (f3-f2)/P.20. See the figure below.
Note: This s-shape curve enables a substantial motor vibration reduction during the acceleration/deceleration, and
thus extends the life span of the belts and the gears.
