13.7 Phase Failure
A failure of one of the three motor or mains can lead to a damage in the frequency
inverter, the motor and the mechanical drive components. To prevent damage to
these components, the phase failure is monitored. Parameter Phase supervision 576
allows to adjust the behavior in case of a failure.
Phase Supervision 576
Function
10 -
Mains
Error Switch-Off
In the case of a phase failure, the fault switch-off takes
place after 5 minutes, fault F0703 is displayed. During
this time, the warning message A0100 is displayed.
11 -
Mains & Motor
Error Switch-Off
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.
20 -
Mains
Shutdown
In the case of a mains phase failure, the drive is stopped
after five minutes, fault F0703 is displayed.
21 -
Mains & Motor
Shutdown
The drive is stopped:
− immediately, in the case of a motor phase failure,
− after 5 minutes in the case of a mains phase failure.
13.8 Automatic Error Acknowledgment
The automatic error acknowledgment enables acknowledgment of the faults Overcur-
rent 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 the parameter Restart delay 579
. If the error must be acknowledged, the
speed of the machine is determined with the quick Search Run function and synchro-
nized to the rotating machine. The automatic error acknowl
edgment makes use of
“Quick Synchronization” operation mode, regardless of the
Search run operation
mode 645
. The information given on this function in chapter "Search run" must be
observed.
With parameter Allowed no. of auto-acknowl. 578
, you can define the number of
automatic error acknowledgements which are permitted within 10 minutes.
An acknowledgement 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 sepa-
rate error acknowledgement counters.
