Limiting the traversing profile
Description
The converter calculates the traversing profile when positioning from specified values for
velocity, acceleration and jerk (= acceleration change with respect to time).
Figure 3-6
If the axis must traverse more slowly or must accelerate at a lower rate or "softly", then you
must set the relevant limits to lower values. The lower that one of the limits is, the longer the
converter needs to position the axis.
Setting the traversing profile limitation
Precondition
You have selected the "Limit" screen and the "Traversing profile limitation" tab.
Procedure
To set the limitation of the traversing profile, proceed as follows:
1. Set the maximum velocity with which the converter may position the axis.
2. Set the maximum acceleration.
3. Set the maximum delay.
The "override" in the traversing blocks or for the direct setpoint input refers to the values
