User Manual of EM730 Series Inverter F04.14=0: linear acceleration and deceleration time is set by the function codes F00.14 and F00.15 by default. The output frequency increases or decreases linearly. The acceleration and deceleration F04.14=1: continuous S-curve acceleration and deceleration The output frequency increases or decreases according to the curve. The S curve is usually where there are relatively low requirements for start and stop, such as elevators and conveyor belts. In the acceleration process shown in Fig. 7–16, t1 is the set value of F04.15, and t2 is the set value of F04.16. In the deceleration process, t3 is the set value of F04.17, and t4 is the set value of F04.18.
The slope of the output frequency remains unchanged between t1 and t2 as well as between t3 and t4. F04.14=2: intermittent S-curve acceleration and deceleration Compared with the continuous S-curve, the intermittent S-curve will not be over-tuned. The current S-curve trend will be stopped immediately according to changes in the settings and acceleration/deceleration time, and the new planned S-curve trend will be applied.
