Buffer For Faults And Alarms - Siemens Sinamics S110 Function Manual

5.3.2

Buffer for faults and alarms

Note
The contents of the fault buffer are saved to non-volatile memory when the Control Unit is
powered down, i.e. the fault buffer history is still available when the unit is powered up again.
NOTICE
The entry in the fault/alarm buffer is made after a delay. For this reason, the fault/alarm
buffer should not be read until a change in the buffer is also recognized (r0944, r2121) after
"Fault active"/"Alarm active" is output.
Fault buffer
Faults which occur are entered in the fault buffer as follows:
