8.1.7.26 Module 25: Static velocity limit values
Notice!
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 velocity with a limit velocity stored in the
configuration. This occurs in the range defined by the range start and end. If a direction-
dependent limit value check is activated with the "direction selection" parameter, the values
of range start and 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. The limit value is not
active in the opposite direction. 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.
