Acknowledge fault
To acknowledge a fault, you have the following options:
• PROFIdrive control word 1, bit 7 (r2090.7)
• Acknowledge via a digital input
• Acknowledge via the Operator Panel
• Switch o󹪜 the converter power supply and switch on again
Faults detected during the converter-internal monitoring of hardware and 󹪝rmware can be
acknowledged only by switching the supply voltage o󹪜 and on again. In the list of faults in
the List Manual, at the corresponding fault codes you may 󹪝nd the information on limitations
when acknowledging.

Figure9-4 Fault history after acknowledging the faults
If at least one of the fault causes in the fault bu󹪜er has been removed and you acknowledge
the faults, the following takes place:
1. The converter shifts the values previously saved in the fault history each by eight indices.
The converter deletes the faults that were saved in the indexes [56…63] before the
acknowledgement.
2. The converter copies the contents of the fault bu󹪜er to the memory locations [8 … 15] in the
fault history.
3. The converter deletes the faults that have been removed from the fault bu󹪜er.
The faults that have not been removed are now saved both in the fault bu󹪜er and in the fault
history.
4. The converter writes the time of acknowledgement 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 to zero.
