Siemens SINAMICS G110M - Faults, Alarm Buffer and Alarm History

9.6 Faults, alarm bu󹪜er and alarm history
Overview
A fault generally indicates that the converter can no longer maintain the operation of the motor.
The extended diagnostics have a fault bu󹪜er and a fault history, in which the converter stores the
most recent faults.
Function description
Faults have the following properties:
• In general, a fault leads to the motor being switched o󹪜.
• A fault must be acknowledged.

Figure 9-4 Fault bu󹪜er
The converter saves incoming faults in the fault bu󹪜er. A fault includes a fault code, a fault value,
and two fault times:
• Fault code: r0945
The fault code and fault value describe the cause of the fault.
• Fault value: r0949 in 󹪝xed-point format "I32", r2133 in 󹪞oating-point format "Float"
• Fault time received = r2130 + r0948
• Fault time removed = r2136 + r2109
The converter takes its internal time calculation to save the fault times.
System runtime (Page 349)
Up to 8 faults can be saved in the fault bu󹪜er.
In the fault bu󹪜er, the faults are sorted according to "Fault time received". If the fault bu󹪜er is
completely full, and an additional fault is received in the fault bu󹪜er, then the converter
overwrites the values with Index [7].
