6 Error Codes and Errors
6.1 Frequency Converter Error Codes
To make sure that the board functions are correctly in all circumstances and that no errors occur, the board
set the fieldbus error 53 if it doesn't have a functional connection to the Ethernet network or if the connection
is faulty.
In addition, the board assumes that there is always at least one functional connection after the first
Modbus/TCP connection. If this is not true, the board will set the fieldbus error 53 in the frequency converter.
Confirm the error by pressing the 'reset' button.
Card slot error 54 may be due to a faulty board, a temporary malfunction of the board or a disturbance in the
environment.
6.2 Modbus TCP
This section discusses Modbus/TCP error codes used by the OPT-CI board and possible causes of the errors.
