In the fault buffer, the faults are sorted according to "Fault time received". If the fault buffer is
completely filled and an additional fault occurs, then the converter overwrites the values with
Index [7].
Acknowledging a fault
To acknowledge a fault, you have the following options:
• PROFIdrive control word 1, bit 7 (r2090.7)
• Acknowledging via a digital input
• Acknowledging via a commissioning tool
• Switch off the converter power supply and switch on again
Faults detected during the converter-internal monitoring of hardware and firmware can
be acknowledged only by switching the supply voltage off and on again. The list of fault
codes and alarm codes includes the note on the limitations on the acknowledgment for the
corresponding fault codes in the List manual.
Fault history
If at least one of the fault causes in the fault buffer has been removed and you acknowledge
the faults, the following takes place:
1. The converter shifts the values previously saved in the fault history by eight indexes.
The converter deletes the faults that were saved in the indexes [56 ... 63] before the
acknowledgment.
2. The converter copies the contents of the fault buffer to the memory locations [8 ... 15] in the
fault history.
3. The converter deletes the faults that have been removed from the fault buffer.
The faults that have not been removed are now saved both in the fault buffer and in the fault
history.
4. The converter writes the time of acknowledgment of the removed faults to "Fault time
removed".
The "Fault time removed" of the faults that have not been removed retains the value = 0.
The fault history can contain up to 56 faults.
Deleting the fault history
To delete all faults from the fault history, set parameter p0952 = 0.
