11.6 Load loss detecon
This funcon serves to detect a load loss during operaon and to then acvate a specic func-
on, for instance the switching of the relay.
Details
If, during operaon, the current motor current falls below the threshold set in 0x4006:001
(P710.01) for at least the me set in 0x4006:002 (P710.02), the internal status signal "Load
loss detected [83]" is set to TRUE:

•
The threshold is set in percent with reference to the rated motor current "Motor rated cur-
rent" 0x6075 (P323.00).
•
The status signal "Load loss detected [83]" can be assigned, for instance, to a digital output
or the relay via the exible I/O conguraon. 4Conguraon of digital outputs ^ 415
•
The load loss detecon is not acve with acve DC braking.

The rated motor current to be set here serves as a reference value for
dierent parameters with a seng/display of a current value in percent.
Example:
•
Motor rated current = 1.7 A
•
Max current 0x6073 (P324.00) = 200 % Motor rated current = 3.4 A
