Special I/O Errors
If a problem is found in the output data of Special I/O, the inverter returns an error code to the input data
without executing the request.
Determine whether or not an error occurred by the most significant bit (word address n, bit 7) of the
Function Code in the input data.
In case of an error, the Function Code in the input data has a value of the output data added with
80 hex.
The table below shows the error code and corrective action for each Special I/O error.
