8 .1.6.12 Module 12: Static velocity limit value 2
Description
The static velocity limit value 2 function compares the current velocity with a velocity
stored in the configuration. This occurs in the configured range, which is defined by range
start and range end .
Notice !
If range start and range 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 range start and range end also 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 range end is irrelevant.
Depending on the selected switching mode , if the value is above or below the defined
limits, the limit value status in module 16 is set and, if configured, the output is appropriately
set via module 4 or 5.
