Functions Common to All the Control Modes
In this example, the commutation to the 2nd ramp (P0102 or P0103) is done by means of one of the digital inputs
from DI1 to DI8, provided that it had been programmed for 2nd ramp function (refer to the section 13.1.3 for more
details).
Note: The setting 0.0 s means that the ramp is disabled.

Description:
This parameter allows that the acceleration and deceleration ramps have a nonlinear profile, similar to an "S", as
showed in the figure 12.2 next.

The S ramp reduces mechanic shock during accelerations/decelerations.
