SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
The following rules apply to the fault buffer:
At POWER ON, the complete fault buffer is deleted.
The faults are entered in the sequence that they occur, in the pa-
rameter of fault case 1, i.e.
– 1st fault that has occurred
––> parameter with index 1
– 2nd fault that has occurred ––> parameter with index 2, etc.
If more than 8 faults occur, then these are not displayed.
Fault case 1 is considered to have been resolved, if, the following is
valid for all of the entered faults:
– the cause has been removed and
– the fault has been acknowledged
The fault buffer is then re–arranged so that the faults of fault case 1
go into fault case 2 and those from fault case 2 into fault case 3 etc.
This means that the parameters of fault case 1 are again free for
additional entries.
If more than 8 fault cases have occurred since the last POWER ON,
then fault case 8 is overwritten, the oldest fault case is eliminated.
If, in fault case 1, there is at least one fault, which must be acknowl-
edged with POWER ON, then this is valid for the complete fault
case.
Reader’s note
A description of the faults, the way in which they can be acknowledged
as well as a list of all the faults, is provided in Chapter 7.
The warnings which occurred, are displayed, bit–coded in P0953 to
P0960.
The ”SIMODRIVE 611 universal” drive signals as to whether there is at
least one message present via the status bit or output signal ZSW1.7
”Warning present/no warning present”.
Reader’s note
A description of the warnings as well as a list of all of the warnings is
provided in Chapter 7.
