At time of broadcast communication, returning of data is not executed, except for the inverters to be

returned, when the inverter number is not matched, and the inverter number has only one character.

This is because there will be a risk of that the returned data may be deformed.

• Data returned when data is processed normally (ASCII mode)

Omissible

1. “(“ (1 byte)

: Start code in ASCII mode

2. INV-NO (2 bytes) : 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 return-
ed to the computer. In broadcast communications, only the destination inverter (with a num-
ber matching up with the smallest effective number) returns data to the computer.
In broadcast communications, no data is returned from any inverters except the inverter
bearing a number that matches up with the smallest effective number.
Ex.: (*2R0000) CR -> (02R00000000) CR)

Data is returned from the inverter with the number 2 only, but no data is returned from
inverters with the number 12, 22 ....

3. CMD (1 byte)

: Command ... The command is also used for a check when an inverter is tripped.

Under normal conditions... The uppercase letter R, W or P is returned, depending on the
command received: R, W or P command.
When an inverter is tripped... The lowercase letter r, w or p is returned, depending on the
command received: R, W or P command.
(The command received is returned with 20H added to it.)

4. Communication No.(4 bytes) :

The communication number received is returned.

5. Data (0 to 4 bytes) : Data ... The data read in is returned for the R command, while the data received is returned

for the W and P commands. If the data received is composed of less than 4 digits, it will be
converted into 4-digit data and returned.
Ex.: (W123412) CR

→ (W12340012) CR)

6. “&” (1 byte)

: Checksum discrimination code (omitted if it is not found in the data received)

7. Sum (2 bytes)

: Checksum ... Omitted if no checksum discrimination code is found in the data received.

ASCII-coded value of the last two digits (4 bits/digit) of the sum of a series of bits (ASCII
codes) from the start code to the checksum discrimination code.

8. “)” (1 byte)

: Stop code (omitted if it is not found in the data received)

9. CR (1 byte)

: Carriage return code
