Extended Functions
828 Function Manual, 03/2013, 6FC5397-1BP40-3BA1
When is the speed limit value recalculated?
The speed limit value is recalculated:
● when the monitoring function is selected,
● when the online offset values (wear parameters) are altered.
Monitor reactions
The system reacts as follows when the speed monitor responds:
● The speed is restricted to the limit value
and
● Interface signal:
DB31, ... DBX83.6 (speed monitoring)
is output.
DB31, ... DBX83.6 = 1 ⇒ Speed monitoring limit reached
DB31, ... DBX83.6 = 0 ⇒ Speed monitoring limit not reached
Note
No error reaction is initiated internally in the control system.
