This parameter enables a smoothing of the acceleration and deceleration ramps. This is
necessary for applications where gentle, but dynamic speed change is important.
Ramp smoothing is carried out for every setpoint change. The value to be set is based on the set
acceleration and deceleration time, however values <10% have no effect.
The following then applies for the entire acceleration or deceleration time, including rounding:
