9.5 Faults, fault bu󹪜er and fault 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.
• Faults are displayed as follows:
– Display in bit3 of status word1 (r0052)
– Display on the converter via the LED RDY
– Display in Startdrive
– Display in the SINAMICS G120 Smart Access
The fault code and fault value describe the cause of the fault.

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
• 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373)
Up to 8 faults can be saved in the fault bu󹪜er.
