8.10.1 CAN bus status (C0359)
C0359 serves to query the current CAN bus status.
If the status of the system bus (CAN) is "Operational", you can use C0866 and C0868 to
check the contents of the data words sent and received via CAN1_IN/OUT.
Value in
C0359
Operating state Description
0 Operational The bus system is fully operational.
1 Pre−operational Only parameters (codes) can be transmitted via the bus system.
A data exchange between nodes is not possible. A special signal on the system
bus (CAN) serves to change to the "Operational" status.
The status can be changed from pre−operational" to operational" by one of
the following actions:
l Master functionality of a higher−level host
l If a node is determined as master via C0352, the operating status is
automatically changed for the entire drive system after the set boot−up time
has elapsed (C0356/1), when power is switched on.
l Reset node ( ^ 94)
2 Warning Faulty telegrams have been received. The node remains passive and does not
send any data. Possible causes:
l Missing bus termination
l Insufficient shielding.
l Potential differences in the grounding of the control electronics
l Bus load is too high.
l Node is not connected to the system bus (CAN).
3 Bus off Too many faulty telegrams: The node has disconnected from the system bus
(CAN). It can be reconnected by:
l Mains reconnection
l Reset node ( ^ 94)
l Reset of the fault message CE4 (TRIP−RESET)

If the system bus (CAN) is in the "Operational" state, you can check the contents of the data words received via
CAN1_IN via C0866 (subcodes 1 and 2).
l The value is bit coded.
