Illustration 1.11 Synchronization References
In each control cycle (1 ms) the profile generator calculates position, speed, and acceleration required to do the specified
movement. The outputs from the profile generator are used at inputs for the position and speed controller as described in
chapter 1.6.4 Control Loops.
