Definition
The number of errors consecutively detected in
communication request data from the computer is greater
than the permissible number of retries.
The parity check result does not match the specified parity.
Sum check code in the computer does not match that of
the data received by the inverter.
Data received by the inverter is in the wrong syntax, data
receive is not completed within the given time, or CR and
LF are not as set in the parameter.
The stop bit length is not as specified by initialization.
New data has been sent by the computer before the
inverter completes receiving the preceding data.

The character received is invalid (other than 0 to 9, A to F,
control code).
