The contents of the current
fault.
The contents of the error that
occurred just prior to the cur-
rent fault.
The reference frequency when
the previous fault occurred.
The output frequency when the
previous fault occurred.
The output current when the
previous fault occurred.
The motor speed when the pre-
vious fault occurred.
The output reference voltage
when the previous fault
occurred.
The main current DC voltage
when the previous fault
occurred.
The output power when the pre-
vious fault occurred.
