Motor Protection By I 2 T- Monitoring - BONFIGLIOLI Agile Operating Instructions Manual

Unlike the operation of a conventional motor circuit breaker which disconnects the equipment to be
protected immediately if the trigger threshold is reached, this function provides the possibility of issu-
ing a warning instead of disconnecting the equipment immediately.
The rated current of the motor circuit breaker refers to the rated motor current stated via parameter
371 of the corresponding data set. The rated values of the frequency inverter are to
Rated Current
be considered accordingly when it comes to dimen-sioning the application.
The function of the motor circuit breaker can be linked to different data sets. In this way, it is possible
to operate different motors via one frequency inverter. Thus, each motor can be equipped with its
own motor circuit breaker.
In case a motor is operated via the frequency inverter for which some setting values, e.g. minimum
and maximum frequency, are changed via the data set switch-over, only one motor circuit breaker
may be installed. This functionality can be set for single or multi-motor operation via parameter
571.

Operating Instructions
The function is deactivated. Factory setting.
In each of the four data sets, the rated values are monitored. Over-
loading the drive is prevented by the fault switch-off "F0401".
The rated values in the first data set are used independently of the
active data set. Overloading the drive is prevented by the fault switch-
off "F0401".
In each of the four data sets, the rated values are monitored. Over-
loading the drive mechanism is signaled by a warning message
"A0200".
The rated values in the first data set are used independently of the
active data set. Overloading the drive mechanism is signaled by a
warning message "A0200".
