S-shaped motion profiles

In the case of the S-shaped motion profile the acceleration is shown and hidden linearly, by which

the jerk is limited. Here the maximum values of torque and speed are not reached simultaneously.

Like this, the motor can be better utilised in the set of characteristic curves for higher speeds.

• The max. attainable speed is higher than for the linear profile.

• Compared to the linear profile the Base process power is greater.

• Since the acceleration is shown and hidden linearly, the maximum acceleration is greater than

in the case of the linear motion profile.
