7. Load position control using an incremental quadrature encoder on load, combined with
speed control of a DC brushed rotary motor having a tachometer on its shaft. The motion
commands (for position, speed and acceleration) in both SI and IU units refer to the load

8. Open-loop control of a 2 or 3-phase step motor in position or speed
into account the transmission ratio between motor and load (rotary or linear). Therefore, the
motion commands (for position, speed and acceleration) expressed in SI units (or derivatives)
refer to the load, while the same commands, expressed in IU units, refer to the motor.
Figure 2.8. No position or speed feedback. Open-loop control: motor position or speed
9. Closed-loop control of load position using an encoder on load, combined with open-loop
control of a 2 phase step motor in speed, with speed reference provided by the position
controller. The motion commands in both SI and IU units refer to the load.
