Phase failure

If a failure of one of the three motor or mains phases is not noticed, the frequency inverter, the
motor and the mechanical drive components may be damaged. In order to prevent these
components from being damaged, the phases are monitored for failure. Via parameter
576 the behavior in case of a phase failure can be set.

Automatic acknowledgment of errors/faults

The automatic error acknowledgment enables acknowledgment of the faults Overcurrent F0500,
Overcurrent F0507 and Overvoltage F0700 without intervention by an overriding control system or
the user. If one of the aforementioned errors occurs, the frequency inverter switches the power
semi-conductors off and waits for the time stated with parameter
must be acknowledged, the speed of the machine is determined with the quick catching function and
synchronized to the rotating machine. The automatic error acknowledgment makes use of "Quick
Synchronization" operation mode, regardless of the search run
information given on this function in chapter 13.5 "Search run" must be observed.

acknowledgments which are permitted within 10 minutes.
An acknowledgment repeated above the permissible number within 10 minutes will result in the
frequency inverter being switched off.
The errors Overcurrent F0500, Overcurrent F0507 and Overvoltage F0700 have separate error
acknowledgment counters.

In the case of a phase failure, the error switch-off takes place after 5
minutes, fault F0703 is displayed. During this time, the warning message
A0100 is displayed.
The phase monitor switches the frequency inverter off:
immediately with error message F0403 in the case of a motor phase
failure,
after 5 minutes with error message F0703 in the case of a mains phase
failure.
In the case of a mains phase failure, the drive is stopped after five
minutes, fault F0703 is displayed.
The drive is stopped:
immediately, in the case of a motor phase failure,
after 5 minutes in the case of a mains phase failure.
