Device parameters and interfaces
Description
The speed limit value function compares the current speed with a stored speed within the
defined range. If the value is above or below the limit value, the dynamic limit value status
in module 23 is set and, if configured, the switching output is appropriately set. Limit value,
hysteresis, range start and range end are transferred with the output data of this module by
the PROFIBUS master. The transferred values are activated by bit 0.0, i.e. if this bit is set,
the BPS 34 compares the current speed with the new limit value conditions.
