9.6 Faults, alarm buffer 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 buffer 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 off.
• A fault must be acknowledged.
Fault buffer
Figure 9-4
The converter saves incoming faults in the fault buffer. 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 fixed-point format "I32", r2133 in floating-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.
Up to 8 faults can be saved in the fault buffer.
In the fault buffer, the faults are sorted according to "Fault time received". If the fault buffer is
completely full, and an additional fault is received in the fault buffer, then the converter
overwrites the values with Index [7].
