Siemens SINAMICS G220 - Fault Buffer

15.8 Fault bu󹪜er
Overview
The converter stores a limited number of faults as incidents in a fault bu󹪜er. As a consequence,
acknowledged faults are kept for diagnostic purposes.
Description of function
A fault includes a fault code, a fault value and 2 fault times. The associated parameters are
shown in the following diagram.
The fault code and fault value describe the cause of the fault. The fault value provides
additional and more detailed information about the fault.
The fault times indicate when the fault occurred and when the fault was eliminated.
Fault bu󹪜er
The converter stores up to 8 incidents in the fault bu󹪜er. The fault bu󹪜er comprises the
current incident and the fault history.
The fault bu󹪜er is kept when the converter supply voltage is switched o󹪜.

The faults are sorted by "Fault time received". If the current incident is full and an additional
fault occurs, then the converter overwrites the values with Index[7].
