The 20 kbaud CAN transmission rate is not supported
Which products are affected?
9300 vector 0.37…90 kW SW V2.1
What happens?
The communication via CAN system bus is not executed.
When does the problem occur?
If the 9300 vector is operated at a system bus with a baud rate of 20kbauds. Although it is possible to select the setting C0351 = 5 (20 kbauds) in case of 9300 vector devices, the inverter does not accept this baud rate and a communication is not started.
Possible diagnostics?
The set baud rate is to be determined in case of communication problems at the system bus (read out code C0351).
Short-term measures/recommendations?
Select another transmission rate for the whole system bus (C0351 = 0 … 4). According to the default setting C0351 is = 0 (500 kbaud).
Evaluation:
It is very improbable that this error occurs since there are generally very few system bus stations which optionally support a baud rate of 20kbauds. Thus it is improbable that the 9300 vector is operated in combination with a system bus with 20kbauds. The error occurs immediately during commissioning.
