maximum value set in the Fullscalespeed(5.22). On the other hand, the deceleration times (6.2,6.4,6.6,6.8
) are expressed as the time necessary to bring the frequency from the maximum value set in the Fullscalespeed
(5.22) parameter to zero. Each of the 4 available ramp selections can be selected using one or two digital inputs
programmed asMultirampsel.

0 = Linear 1 = S-Shape
When linear ramps are set (Linear) the motor speed varies in a way that is directly in proportion to the
frequency.
When S-shape ramps are set (S-Shape) it is possible to avoid sudden mechanical variations in the system at the
beginning and end of the acceleration and deceleration phase.
The ramp time, meaning the time necessary to accelerate from zero to the maximum frequency value
set, is given by the sum of the linear ramp time and that of the associated Jerks (see par. 6.13 – 6.20).
The Bypass excludes the ramp circuit and the reference is brought directly to the speed regulator input.
With Off the ramp reference is set to zero.

1 or 2 digital inputs can be used to select one of the 4 available sets of ramps.
The origin (source) of the command to enable the ramp selection function can be selected from the “L_DIGSEL2”
selection list.
