F04.14=0: linear acceleration and deceleration
The output frequency increases or decreases linearly. The acceleration and deceleration
time is set by the function codes F00.14 and F00.15 by default.
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.
