10.5 RAMPS AND BRAKES SETUP
10.5.1 RAMP 1
P3.4.1.1 RAMP 1 SHAPE (ID 500)
Use this parameter to make the start and the end of the acceleration and deceleration ramps
smoother.
With the parameters Ramp 1 Shape and Ramp 2 Shape, you can make smoother the start
and the end of the acceleration and deceleration ramps. If you set the value to 0.0%, you get
a linear ramp shape. The acceleration and deceleration act immediately to the changes in
the reference signal.
When you set the value between 1.0% and 100.0%, you get an S-shaped acceleration or
deceleration ramp. Use this function to reduce mechanical erosion of the parts and current
spikes when the reference changes. You can modify the acceleration time with parameters
P3.4.1.2 (Acceleration Time 1) and P3.4.1.3 (Deceleration Time 1).

P3.4.1.2 ACCELERATION TIME 1 (ID 103)
Use this parameter to set the time that is necessary for the output frequency to increase
from zero frequency to maximum frequency.
P3.4.1.3 DECELERATION TIME 1 (ID 104)
Use this parameter to set the time that is necessary for the output frequency to decrease
from maximum frequency to zero frequency.
