4.1.8.1 Speed for positioning
Standard speed for all positionings and motion functions.
The value can be changed during operation via the bus or via the motion sets.
This setting is not relevant for the "rotation speed" operating mode.
4.1.8.2 Acceleration for positioning and velocity control
Standard acceleration for all positionings and motion functions.
The value can be changed during operation via the bus or via the motion sets.
4.1.8.3 Acceleration / deceleration for positioning
Standard deceleration for all positionings and motion functions.
The value can be changed during operation via the bus or via the motion sets.
If "0" is entered, the acceleration value is accepted as deceleration.
4.1.8.4 Jerk limit for positioning
Standard jerk for all positionings and motion functions.
The value can be changed during operation via the bus or via the motion sets.
In the operating modes:
Speed control
Velocity and
Gearing
the jerk is not limited.
Description of jerk
Jerk
The jerk (marked with ”4” in the drawing below) describes the change in ac-
celeration (derivation of the acceleration)
The maximum change in acceleration is limited via the jerk limitation.
A motion process generally starts from a standstill, accelerates constantly at the
specified acceleration to then move at the selected speed to the target position.
The drive is brought to a stop before the target position with the delay that has
been set in such a manner as to come to a complete stop at the target position. To
reach the set acceleration and deceleration, the drive must change the acceleration
(from 0 to the set value or from the set value to 0).
This change in speed is limited by the maximum jerk.
