8.1.2 Possible fault codes
The possible fault codes are shown in the following table. The used fault codes depend on the servo valve
model and hardware. The fault code 0 means that no fault is pending.
To get the sub-index of the fault reaction type <FaultReactionType> (0x2830), the fault code must
be incremented by one.
