SICK nanoScan3 I/O

For dynamic inputs, you must also specify the tolerance by which the measured speeds
of t
he two incremental encoders are allowed to deviate from one another, e.g. when
cornering. The value is given as a percentage of the higher of the two speeds (whether
forwards or backwards). In case of differences, the speed with the higher value is
always used. The tolerance is allowed to be exceeded for a certain period of time. The
safety laser scanner then switches the safety outputs to the OFF state.
The period of time depends on the vehicle speed:
•
Vehicle speed -10 cm/s … +10 cm/s: No shut-off, no matter how large the devia‐
tion between the measured speeds is.
•
Vehicle speed -30 cm/s … -10 cm/s or +10 cm/s … +30 cm/s: The tolerance is
allowed to be exceeded for a maximum of 60 seconds.
•
Vehicle speed ≤ -30 cm/s or ≥ +30 cm/s: The tolerance is allowed to be exceeded
for a maximum of 20 seconds.
•
Vehicle speed in the range ≤ -10 cm/s or ≥ +10 cm/s: Different directions of rota‐
tion of the incremental encoders are tolerated for a maximum of 0.4 s.
