4.9.7 Height preselector and TruckCom
The height preselector can also be managed via TruckCom. This
makes it possible to enter the saved heights on a PC or PDA.
In this way, you can archive them in a file and update a truck using the
settings from the file.
4.9.8 Lift/lowering movement
When the sequences are performed, the lift movements are checked by
the service parameters 341, 342, 371 – 377 to get them to interrupt the
movement at the right height, and as gently and precisely as possible.
The transfer near the target height is limited by a curve that is defined
by a number of parameters:
341: Max. lift speed, 342: Max lowering speed, v
lift
: Lift speed, h
targ
:
Target height, d
lift
: Lift movement length
Once the forks are nearer to the target height than the specification of
parameters 375/376, Braking Distance Lift/Lower, the movement slows
in three stages to the height set by parameters 373/374, Creep Dis
-
tance Lift/Lower.
Once the forks are nearer to the target height than the creep distance,
the forks move at the speed defined by parameters 371/372, Creep
Speed Lift/Lower.
Once the forks reach the target height, the movement is stopped.
If the measured stop height differs from the target height by more than
the maximum error, defined byparameter 377, Max. StopHeight Error, a
warning code is displayed at the same time as the CID emits a warning
sound.
