SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
In the list of faults and warnings (refer to Chapter 7.3), for each fault
and warning, an explanation is given under ”Acknowledge”, as to how
they can be acknowledged after the cause has been removed.
Faults, which are to be acknowledged with POWER ON, can be alter-
natively acknowledged as follows:
1. POWER ON
––> power–off/power–on ”SIMODRIVE 611 universal”
2. Press the POWER–ON RESET button on the front panel of the con-
trol board
3. POWER–ON RESET with the ”SimoCom U” tool
The processor runs up again, all of the faults are acknowledged, and
the fault buffer is re–initialized.
Faults, which are to be acknowledged with RESET FAULT MEMORY,
can be alternatively acknowledged as follows:
Notice
Prerequisites when acknowledging:
Disable the controller enable via terminal 65.x
or
Set the PROFIBUS control signal STW1.0 to ”0”
From SW 6.1 and for P1012.12=1, the fault can also be
acknowledged without this prerequisite. However, the drive then
remains in the ”Power–on inhibit” state (refer to Chapter 5.5
”Generating the power–on inhibit”; Fig.5-9).
Set the appropriate bus signal (e.g. for the CAN bus, from SW
8.1)
1. Carry–out POWER ON acknowledgment
In addition to the POWER ON faults, all of the faults, which can be
acknowledged with RESET FAULT MEMORY, are also acknowl-
edged.
2. Set the input terminal with the ”reset fault memory” function to ”1”
3. Press button P on the display and operator control unit
4. Using PROFIBUS–DP: Set STW1.7 (reset fault memory) to ”1”
5. Set terminal R on the NE module to ”1”
When this terminal is energized, ”reset fault memory” is effective for
all of the control boards of the complete drive group.
6. For the ”SimoCom U” tool in the dialog box ”Alarm report” by press-
ing the ”Reset fault memory” button
If a fault is acknowledged, before the cause, e.g. overtemperature, DC
link undervoltage etc. was removed, then the fault message is subse-
quently de–activated at that instant in time when the cause is no longer
present. The fault memory must no longer be reset again.
