F1012=5（s）: The setting value of acceleration time.
F1022=50（%）: S-shaped curve with medium-curvature start.
F1023=50（%）: S-shaped curve with medium-curvature arrival.
F1024=0 （%）: The slope of middle part is the same with that in linear acceleration.

● Examples of S-shaped curves combined according to the set values are shown below. In each of these examples,
acceleration/deceleration reference time and acceleration/deceleration time settings are set to the same value.
F1011=50（Hz）F1012=5（s）F1016=5（s）
Example 1) F1022=100 F1023=100 F1024=100 F1025=100 F1026=100 F1027=100
The arrival time is equal to that in linear acceleration / deceleration. However, since the slope of the middle portion is twice
as that in linear acceleration/deceleration mode, the current limiting function may operate depending on the magnitude of the
load inertia.
Example 2) F1022=100 F1023=100 F1024=100 F1025=100 F1026=100 F1027=0。
The curvature of the S-shaped acceleration/deceleration's start portion and end portion become maximum, and the slope of
the S-shaped acceleration/deceleration's middle portion becomes the same as that in the linear acceleration/deceleration
mode.
Example 3）F1022=0 F1023=0 F1024=0 F1025=0 F1026=0 F1027=0。
The result is the same with that in the linear acceleration/deceleration mode.
Example 4）F1022=100 F1023=100 F1024=0 F1025=0 F1026=0 F1027=100。
This setting value applies to the acceleration/deceleration of loads with square-law decreasing torque (such as fan etc.).
