Control Parameters - BONFIGLIOLI actice Instruction Manual

4.12
For the monitoring of the system bus and the display of the internal states, two con-
trol parameters are provided. There is a report of the system bus state and a report of
the CAN state via two actual value parameters.
The parameter
erational, Stopped state. A PDO transfer is only possible in the Operational state. The
state is controlled by the system bus master (PLC / PC / frequency inverter) via NMT
telegrams.
The parameter
layer. If there are transmission errors, the state changes from OKAY to WARNING
until the cancellation of the communication with BUS-OFF. After BUS-OFF, the CAN
controller is automatically re-initialized and the system bus started again.
Note:
After Bus-OFF, the system bus in the frequency inverter is completely reinitialized.
There is a new boot-up message from the node and an emergency telegram with the
Bus-OFF message is transmitted. The change of state of the node to Operational is
done by the Start-Remote-Node telegram cyclically sent by the system bus master.
