2: S-curve acceleration/deceleration B
In this curve, the rated motor frequency is always the inflexion point. This mode is fb usually used in applications where
acceleration/ deceleration is required at the speed higher than the rated frequency.
When the set frequency is higher than the rated frequency, the acceleration/deceleration time is:
In the formula, f is the set frequency, fb is the rated motor frequency and T is the acceleration time from 0 Hz to the rated
frequency fb.
P1.08
Time proportion of
S-curve start segment
Default
30.0%
Setting Range
0.0%~ (100.0%-P1.09)
P1.09
Time proportion of
S-curve end segment
Default
30.0%
Setting Range
0.0%~ (100.0%-P1.08)
These two parameters respectively define the time proportions of the start segment and the end segment of S-curve acceleration/
deceleration A. They must satisfy the requirement:
P1.08 + P1.09 ≤ 100.0%.
In Figure 4-2, t1 is the time defined in P1.08, within which the slope of the output frequency change increases gradually. t2 is the
time defined in P1.09, within which the slope of the output frequency change gradually decreases to 0. Within the time between
t1 and t2, the slope of the output frequency change remains unchanged, that is, linear acceleration/deceleration.
P1.10
Stop mode
Default
0
Setting Range
0
Decelerate to stop
1
Coast to stop
