2) Error Processing (Binary mode)

In case an error occurs, communication error command (4EH(N) or 6EH(n)) and the error type num-
ber is returned to the computer in addition to the checksum. At time of broadcast communication of
the binary mode, returning of data is not executed except for the inverter to be returned (inverter
number 00H) and when the inverter number is not matched. This is because there will be a risk that
the returned data may be deformed.

“N” or “n” (1 byte)

: Communication error command.    Also for check during an inverter trip (includes standing

for retrying and trip holding).    “4EH (N)” when normal, “6EH (n)” during an inverter trip.

DATA (2 bytes)

: Error code (0004)
    0004

 : Checksum error (The checksum does not match)

    No return : Command error, format error (specified number of bytes is not received in 1sec,

or parity error, overrun error or framing error), inverter number mismatch, and
inverter number other than 00H in broadcast communication.
