6.7. S-shaped ramps
In order to reduce the jerk and to therefore prevent the drive components from damage,
a smoothing factor can be set for the acceleration/deceleration ramps.
Details
In the default setting, the motor is accelerated and decelerated with linear ramps since
this is the most used configuration. The setting of a smoothing factor causes S-shaped
ramps. This leads to a smoother starting and braking behaviour which, for instance, is
used for sensitive machine parts with backlash. It has to be observed here that the setting
of a smoothing factor causes longer acceleration and delay times (see the following
diagrams).

Factor for S-rounding of the acceleration/deceleration ramps.
•
With the setting "0.0", the S-rounding is deactivated and
acceleration/deceleration with linear ramps is carried out.
