 Data returned when data is not processed normally (ASCII mode)
In case an error occurs, communication error command (4EH(N) or 6EH(n)) and the error type
number is returned to the computer in addition to the checksum. At time of broadcast communica-
tion of the binary mode, returning of data is not executed except for the inverter to be returned (in-
verter 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.

Checksum area
: Start code in ASCII mode
: Communication error command ... This is also used for the checking of inverter trip.
"N" is during normal condition and "n" is during trip.
: Inverter number (omitted if it is not found in the data received) ... 00 (30H, 30H) to 99 (39H,
39H)
If the inverter number matches up with that specified using a parameter, data will be re-
turned to the computer. In broadcast communication, only the destination inverter (with a
number matching up with the smallest effective number) returns data to the computer.
: Error code (0000~0004)
0000 ... Impossible to execute (Although communication is established normally, the
command cannot be executed because it is to write data into a parameter whose
setting cannot be changed during operation (e.g., maximum frequency) or the
EEPROM is faulty.)
0001 ... Data error (The data is outside the specified range or it is composed of too many
digits.)
0002 ... Communication number error (There is no communication number that matches.)
0003 ... Command error (There is no command that matches.)
0004 ... Checksum error (The checksum result differs.)
: Stop code ... This code is omitted if it is not found in the data received.
... Impossible to execute (e.g., a change of maximum frequency data during opera-
CR
tion)
... Data error (Data is outside the specified range.)
CR
... No communication number (There is no communication number that matches.)
CR
... There is no command that matches. (Commands other than the R, W and P
CR
commands)
