The relationship between output frequency and time increases or decreases according to a constant slope, as shown
in the following figure.
1: S-curve acceleration / deceleration
The relationship between output frequency and time increases or decreases according to the S-shaped curve. When
acceleration starts and speed arrives, and when deceleration starts and speed arrives, the speed set value is in the
S-shaped curve state. This can make acceleration and deceleration smooth and reduce the impact on the load. S-curve
acceleration and deceleration mode is suitable for the start and stop of transporting and transferring loads, such as
elevators and conveyor belts. As shown in the figure below: t1 is acceleration time, t2 is deceleration time, ts is start time of
S curve, te is end time of S curve, 01.06=ts/t1,01.07=te/t2.
