Emergency-Message, Fault Shutdown - BONFIGLIOLI Active Cube User Manual

7.9.4 Emergency-Message, fault shutdown

As soon as a fault shutdown occurs in a slave frequency inverter, the emergency
telegram is transmitted. The emergency telegram marks the node ID for the identifi-
cation of the failed node via its identifier and the existing fault message via its data
contents (8 bytes).
The emergency telegram has the identifier 128 + node ID.
After a fault acknowledgment, another emergency telegram is transmitted, with the
data content (Byte 0 ...7) being set to "0" this time. This identifies the subscriber's
repeated readiness for operation. If a further fault occurs subsequently, it is transmit-
ted in a new emergency telegram.
The acknowledgment sequence is based on the definitions according to CANopen.
Data contents of the emergency telegram:
Bytes 0, 1 and 2 are firmly defined and compatible with CANopen.
Bytes 6/7 contain the product specific VECTRON error code.
