8.1 Fault reaction
If a malfunction occurs, the servo valve software throws a fault. The corresponding fault is set in the fault state
<FaultStatus> (0x2831) and <FaultRetainStatus> (0x2834) parameters in bit coded form. If no fault reaction
for this fault is defined within the parameter <FaultReactionType> (0x2830) no further fault reaction is done. If
a fault reaction is configured for the thrown fault code at least an emergency message is sent and the <Error-
Register> (0x1001) parameter will be set according to the error group of the fault code. Then the fault code
and the error code are saved in an array <StandardErrorField> (0x1003) which holds the last eight thrown
faults. Afterwards the error description string is saved in the array <FaultReactionDescription> (0x2832). The
<FaultHistoryNumber> (0x2833) is set to the number of thrown faults.
If the configured fault reaction of the actual thrown fault requests a change of the device state, the corre-
sponding transition of the device state machine will be forced.
