■ Inverter → computer
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.

If the inverter number matches up with that specified using a parameter, data will be re-
turned to the computer. In broadcast communications, only the destination inverter (with a
number 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 ....
: 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.)
The communication number received is returned.
turned 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
