7.2
Acceleration and deceleration curvature (A003~A004)
When rise the value of A003(A004), the s-curvature is bigger.
In this case, the acceleration and deceleration time can be modified.
The curvature variable in this formula limits.

7.3
Acceleration stop function (A005~A006)
When the moment of inertia for the load is high, this is the function to wait until the slip of the
motor on starting becomes smaller.
Use when the over current trip occurs on starting.
