ƒ

Selection 2: Warning

Error messages have been received if the state is "Warning". The CAN node is now only
passive; no more data are sent from the inverter.

The reason for this situation can be:

– A missing bus terminator
– Inadequate shielding
– Potential differences at the ground connection for the control electronics
– An excessively high bus load
– CAN node is not connected to the bus

ƒ

Selection 3: Bus Off

The frequency of the erroneous messages has resulted in the CAN node decoupling itself
from the bus. It is possible to switch to the "Pre−Operational" state with:

– A trip reset
– A reset node
– Reconnection to the mains

ƒ

Selection 4: Stopped

Only NMT telegrams can be received.

The state can be changed to "Pre−Operational" by:

– Reconnection to the mains
– Reset node via the bus system
– Reset node via the code C0358
