For some applications it is an advantage when the drive starts and stops jerk-free.
This function is achieved through a balancing of the acceleration and deceleration
ramps. The balancing time, S-curve time, is adjusted with the parameters
SP.15...SP.18.

In order to drive defined ramps at activated S-curve times the preadjusted acceleration and deceleration
times (SP.11...SP.14) must be larger than the corresponding S-curve times (SP.15...SP.18).
Example for acceleration at rotation clockwise
At the beginning and end of the acceleration ramp a parabolic curve is driven for the time adjusted in parameter SP.15. As
a result the adjusted ramp time is extended by SP.15.
*1 If the value „off“ is adjusted in these parameters (for rotation counter-clockwise), then the values adjusted in the
parameters for rotation clockwise are valid.
*2 If in addition to parameters SP.17 and SP.18 (S-curve time for rotation counter-clockwise) the value „off“ is also
adjusted in parameter SP.16, then the time adjusted in parameter SP.15 is valid for all S-curve times.
Total acceleration time = acceleration ramp (SP.11) + S-curve time acceleration (SP.15)
