permit the comparison between the current velocity as measured
by the AMS 335
i
and a limit stored in the respective object.
Notice!
Notice regarding velocity monitoring 1 - 4 and dynamic velocity monitoring
If
position start
and
position end
are identical, velocity monitoring is not activated.
If a direction-dependent limit value check is activated via the
direction selection
parameter,
the values of
position start
and
position end
also define the direction. The check is always
performed from
position start
to
position end
. For example, if the range start is "5500"
and the range end is "5000", the direction-dependent check is only performed in the direc-
tion from "5500" to "5000". The limit value is not active in the opposite direction.
If the check is independent of direction, the order of
position start
and
position end
is irrel-
evant. Depending on the selected
switching mode
, if the value is above or below the defined
limits, the limit value status in object 2026
h
is set and, if configured, the switching output is
set via object 2050
h
or 2051
h
.
Notice!
The explanations given above on the “Position start” and “Position end” parameters apply
analogously for objects 2022

through 2025
