8.2.8 Positioning

Change to the Profile register and go to the Basic values input area, in Selection select the
Positioning mode.
This function serves to conveniently create motion profiles for positioning applications.
• Only the trapezoidal element and the acceleration, S shape and S-ramp time options are avail-
able.
• Selection and limit values which must not be exceeded are represented in red.
• The speed is calculated from the values for the path and the time in accordance with the limit
values. If the path cannot be travelled within the specified time, the time will be prolonged
automatically.
• Simple optimisation of the temporal characteristic of an element.
• In order to obtain the shortest time, select a very small value (e.g. 1 ms) in the Time input field.
Accept the value. DSD calculates the smallest possible value.
Legend Description
Type
Trapezoidal element.
• Other elements are not available in the Type input area.
S shape Trapezoidal acceleration and deceleration phase.
• When the selection field is activated, the Jerk input field is shown.
 Non-linear motion profiles ( 267)
Base values
• Entry of the speed.
• Grayed out input fields are deactivated. The values are calculated automatically.
