In each control cycle (1 ms), the profile generator calculates position, speed, and acceleration required to do the specified move-
ment. The outputs from the profile generator are used as inputs for the position and speed controller.
6.2.4 Fieldbus References
Fieldbus references for speed and position are set via the process data (PCD) configuration as shown in the example:
