The tolerance is allowed to be exceeded for a certain period of time. After that the sys‐
t
em switches to a safe state (lock-out). The period of time depends on the vehicle
speed, see figure 59, page 81.

•
If t
he vehicle speed is in the range between –10 cm/s and +10 cm/s, then no
shut down occurs, irrespective of how long the deviation between the incremental
encoders is present.
•
If the vehicle speed is between –30 and –10 cm/s or +10 and +30 cm/s, then
the maximum period of time for which a deviation is tolerated is 60 s.
•
If the vehicle speed is in the range ≤–30 cm/s or ≥+30 cm/s, then the maximum
period of time for which a deviation is tolerated is 20 s.
•
If the vehicle speed is in the range ≤–10 cm/s or ≥+10 cm/s, then different direc‐
tions of rotation on the incremental encoders are only tolerated for 0.4 s.
