Value description
8.1.4 Error codes depending on fault codes
The following table combines the Moog specific fault codes with the error codes, send with an emergency
message.
Details about the error codes used for monitoring: Chapter "7.15 Monitoring", page 232
<FaultReactionType> Description
0 (NONE) No fault reaction, error is ignored.
Independent whether a malfunction for the monitored fault is detected, the device does not react on this
event. The device continues to operate. Special care must be taken, as the malfunction may have an im-
pact on the device.
1 (EMERGENCY) Send an emergency message.
If a malfunction for the monitored fault is detected, an emergency message will be sent onto the field bus.
The device continues to operate. Special care must be taken, as the malfunction may have an impact on
the device.
2 (FAULT_DISABLED) Switch to device state 'FAULT_DISABLED'.
If a malfunction for the monitored fault is detected, the device state machine enters the
'FAULT_DISABLED' state and an emergency message will be sent onto the field bus. The power stage of
the device is switched off, while all device functions are still alive. The device must be re-enabled with the
control word or the enable signal in order to return into normal operation.
3 (FAULT_HOLD) Switch to device state 'FAULT_HOLD'.
If a malfunction for the monitored fault is detected, the device enters the 'FAULT_HOLD' state and an
emergency message will be sent onto the field bus. The hold setpoint of the device is in effect and ad-
justed. The device must be re-enabled with the control word or the enable signal in order to return into nor-
mal operation.
127 (FAULT STOP) Switch to device state 'NOT_READY'.
If a malfunction for the monitored fault is detected, the device enters the 'NOT_READY' state and an emer-
gency message will be sent onto the field bus. The power stage of the device is switched off, while almost
all device functions are stopped. The device must be serviced.
