8.1.7.26 Module 25: Dynamic speed limit value
Note!
Underlined in the CR column are the modules which must be activated in addition to the cur-
rent module.
Description
The limit value function compares the current speed with a limit speed stored in the config-
uration. This occurs in the range defined by the range start and end. If a direction-dependent
limit value check is activated via the direction selection parameter, the values of range start
and range end define the direction. The check is always performed from range start to range
end. For example, if the range start is "5500" and the range end is "5000", the direction-
dependent check is only performed in the direction from "5500" to "5000". If the check is
independent of direction, the order of range start and end is without meaning. If the value is
above or below the limit value, the limit value status in module 23 is set and, if configured,
the switching output is appropriately set.
