6. 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

7. Speed or torque control of a DC brushed rotary motor with a tachometer on its shaft.
Scaling factors take into account the transmission ratio between motor and load (rotary or
linear). Therefore, the motion commands (for 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

8. Open-loop control of a 2 or 3-phase step motor in position or speed. Scaling factors take
into account the transmission ratio between motor and load (rotary or linear). Therefore,
