10.6. Load loss detection
This function serves to detect a load loss during operation and to then activate a specific
function, for instance the switching of the relay.
Details
If, during operation, the current motor current falls below the threshold set in 0x4006:001
(P710.01) for at least the time 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
current" 0x6075 (P323.00).
•
The status signal "Load loss detected [83]" can be assigned, for instance, to a digital
output or the relay via the flexible I/O configuration.

• The load loss detection is not active with active DC braking.

The rated motor current to be set here serves as a reference value for
different parameters with a setting/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
