“F1” is the 1
st
active fault (not yet acknowledged).
“F2” is the 2
nd
active fault (not yet acknowledged).
“F1e” is the occurrence of the fault acknowledgement of F1 & F2 – this moves the values in
the 2 indices down to the next pair of indices where they are stored.
The most recent fault events are stored in indices 0 and 1.
For example:
If the inverter trips on undervoltage and then receives an external trip before the
undervoltage is acknowledged you will get:
Index 0 = 3 Undervoltage
Index 1 = 85 External trip
Whenever a fault is put into index 1 (F1e) the existing fault history is moved as shown in the
diagram.
Note
See list of fault codes list in Section 6
Index 2 is only used if a 2
nd
fault occurs before the 1
st
is acknowledged.
