Anti−collision sensor SensoPart
The SensoPart permanently measures the distance to a reflector on the vehicle ahead. The
distance is read out via a serial interface RS485 by the vehicle control system and is
evaluated according to the function parameterised.
Via a digital signal source (digital inputs, linkage result, etc
…
) you can switch over between
two SensoPart parameter sets (close−up range and long range, e. g. loaded or empty
vehicle).
For each parameter set, 2 distances, including hystereses in [mm], can be parameterised.
When an object is detected within the approach distance [mm] (speed limit), the speed is
limited to a freely parameterisable threshold [Hz].
The required braking distance towards the vehicle ahead, calculated via the speed [Hz] that
is currently travelled and the deceleration set [Hz/s], is added to the stopping distance
[mm]. Furthermore a parameterisable offset [mm] is added to this value. If the calculated
minimum braking distance to the vehicle ahead is reached, the control system starts to
brake on the parameterisable creeping speed [Hz]. When the parameterised stopping
distance [mm] is reached, a stop takes place. Only if the distance to the vehicle ahead is
increased via the minimum dhysteresis, a possibly parameterised start−up delay
time is awaited and the vehicle accelerates to the approach speed again. If the approach
dhysteresis are exceeded, the vehicle is accelerated to the travelling speed
specified.
The "trip−out switching threshold" parameter (C0461) is used to stop the vehicle as quickly
as possible when the set value falls short if the alignment between reflector and SensoPart
(e.g. in curves) is poor.

Note!
If no SensoPart is used, you have to deactivate the function in C0460!
