Faults with common configuration settings (category 2 faults)
These faults have common configuration parameters for maximum number of fault
occurrences and adjustable time period between reset attempts. The faults share two
parameters:
• one for setting maximum number of fault occurrences and
• one for controlling the time period between reset attempts.
The two parameters are linked to a group of 20 parameters that can be configured to hold
one fault code each. All fault codes entered in the parameter group can be cleared with the
Autoreset function. The first 11 parameters in the group are predefined with fault codes
known to have sometimes caused nuisance tripping of the inverter. The remaining nine
parameters can be configured with any fault codes that may be needed by the user to be
automatically reset.
The table below shows the category 2 faults:

Fault history
The inverter fault history is accessed from the Events menu or from parameter group 104
Warnings and faults. In the Events menu, active faults and warnings are shown under
separate submenus. All faults are shown under one single submenu. Warnings and other
events are shown in another submenu. Other events are, for example, faults that are reset
by the user or the Autoreset function.
Fault and warning codes can be read through the fieldbus interface. For more information,
see chapter Fieldbus interfaces.
The fault history is cleared with parameter 196.51 Clear fault and event logger.
