15.0 Functional Description
This chapter describes the following functional blocks in more detail:
The motion detection and I
15.1 Position Controller
15.1.1. Positioning and Motion Control
A positioning command will produce a motion as illustrated in Figure 7. A motion starts with an acceleration phase from minimum
velocity (Vmin) to maximum velocity (Vmax), and ends with a symmetrical deceleration. This is defined by the control logic according to
the position required by the application and the parameters programmed by the application during configuration phase. The current in
the coils is also programmable.
