Description of Function Codes
When the set frequency is higher than the rated frequency, the acceleration/

Function Code
Time proportion of S-curve
P6-08
start segment
Time proportion of S-curve
P6-09
end segment
These two parameters respectively define the time proportions of the start segment and the
end segment of S-curve acceleration/deceleration. They must satisfy the requirement: P6-08
+ P6-09 ≤ 100.0%.
In Figure 6-12, t1 is the time defned in P6-08, within which the slope of the output frequency
change increases gradually. t2 is the time defned in P6-09, 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.
