Regarding Fig. 3/6:

1 to 3: Setpoint value and actual value curves. The setpoint
value here refers to the reference setpoint value which is genĆ
erated by the trajectory planning.

4 to 6: Enlarged illustration of the control fault and the two
tolerances. The following error tolerance (11 mm) is much
greater than the positioning tolerance (0.1 to 10 mm or 0.004
to 0.394 in).

7: The MC signal determines which tolerance is used.
