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
•
Setting a smoothing factor produces S-shaped ramps for the acceleration/deceleration.
•
This type of acceleration/deceleration is for example required for sensitive machine parts
with a certain amount of play.
•
The total acceleration time and deceleration time increase correspondingly (see the follow-
ing examples).
Example 1: smoothing factor = 50 %
•
Total acceleration time = 1.5 * acceleration time
•
Total deceleration time = 1.5 * deceleration time
Example 2: smoothing factor = 100 %
•
Total acceleration time = 2 * acceleration time
•
Total deceleration time = 2 * deceleration time

S-Ramp characteristic: Smoothing factor
(S-ramp char.: S-Ramp smoothing)
0.0 ... [0.0] ... 100.0 %
Factor for S-rounding of the acceleration/deceleration ramps.
•
With the setting "0.0", the S-rounding is deactivated and accelera-
tion/deceleration with linear ramps is carried out.
