Speed Ramps Overview
6.6.10.9.1
Ramps are used for reaching the desired speed reference in a controlled manner. The parameters in the Speed Ramps parameter group is
used to select the ramp type and to adjust their shapes.
Ramps 1–4 can be configured as linear or S-ramps. A linear ramp provides the motor a constant acceleration. The S-ramp allows the drive
to compensate for jerk in the application and/or to reduce sway.
The following diagram illustrates how the ramp parameters are used for adjusting the ramp profiles.

Furthermore, the drive supports a variable ramp profile, which allows the changing of the acceleration and deceleration time
dynamically with analog inputs.
