enable comparison of the velocity currently measured by the

, with a limit value stored in the respective object.
Note regarding velocity monitoring 1 - 4 and dynamic velocity monitoring
If range start and range end are identical, velocity monitoring is active over the entire
traversing range.
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 position start is "5500" and
the position end is "5000", the direction-dependent check is only performed in the direction
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 irrele
-
vant. Depending on the selected switching type, 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
.
