42 SICK LSI Technical Description - 06/98
– Number of pulses of the incremental sensors per centimeter
travel of your vehicle: Enter here the values you determined
for your application
(a calculation example for a typical application is given in the
appendix, section 11.1).
Note:
The maximum possible speed of the vehicle is displayed in the
box.
The minimum recordable speed is ± 10 cm/s.
For technical reasons, and to provide greater availability, lower
speeds are ignored, or interpreted as 0 cm/s.
– Speed difference between the two incremental sensors: The
recommended setting is 25 %. The values of the two
incremental sensors must only deviate from each other by
up to this amount.
Note:
The speed difference entered here may be exceeded for max.
20 seconds, e.g. for cornering. Activation of the protective field
in such cases is always based on the higher of the two speed
values. This guarantees maximum safety.
– Set the restart behavior for the outputs according to your
needs.
(In this example delayed restart after two seconds is
selected for the configured output OSSD A.)
– Startup testing off: This is the recommended setting.
– Log on and name sensors:
(In the example the two sensors used are named according
to their position on the vehicle: one sensor is mounted at the
front, the other at the rear, to monitor forward and reverse
movement of the vehicle.)
