7.1 Mains switch-on
After the CAN participant has been switched on it logs into the system with the CAN ID: 700
hex
+ Node
ID.
Example
Node ID: 50

à 32
hex
Mains On à if the participant was recognised 732
hex
is transmitted.
As no valid telegram was sent at this time, the inverter switches to the status "Starting disabled" ( à
status word: 0B40).
