CANopen status
(CANopen status)
•
Read only
Display of the current CAN bus state.
0 Initialisation
CAN bus initialisation active.
•
The initialisation is started automatically at mains connection. During
this phase, the inverter us not involved in the data exchange process
on the CAN bus.
•
The standard values are re-written to all CAN-relevant parameters.
•
When the initialisation process has been completed, the inverter
automatically adopts the "Pre-Operational" state.
1 Reset node
"Reset Node" NMT command active.
•
Initialisation of all CAN-relevant parameters with the values stored.
2 Reset communication
"Reset Communication" NMT command active.
•
Initialisation of all CAN-relevant parameters with the values stored.
4 Stopped
Only network management telegrams can be received.
5 Operational
Parameter data and process data can be received.
127 Pre-Operational
Parameter data can be received, process data are ignored.

CANopen controller status
(Controller status)
•
Read only
Status display of the internal CANopen controller.
1 Error active
The inverter is a fully-fledged communication node at the CANopen net-
work. It is able to transmit and receive data and to report faults.
2 Error passive
The inverter can only passively indicate faulty reception via the ACK
field.
3 Bus off
The inverter is electrically separated from the CANopen network. In
order to exit this state, the CANopen interface must be reset.

CANopen emergency telegram
If the error status changes when an internal device error occurs or is remedied, an emergency
telegram is sent to the NMT master once.

of emergency telegrams following quickly in succession.
8.4.7
CANopen heartbeat protocol
The heartbeat protocol can be used for node monitoring purposes within a CAN network.
Details
Basic procedure:
1
.
A heartbeat producer cyclically sends a heartbeat telegram to one or several receivers (con-
sumers).
2
.
The consumer(s) monitor(s) the heartbeat telegram for arrival on a regular basis.
The inverter can be configured as producer or as consumer to monitor up to four other nodes.
