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 "Rated motor 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.

Configure digital outputs

–

An error response can be selected in 0x4006:003 (P710.03).

–

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