■ Inverter → Computer
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.

If the inverter number matches up with that specified from the operation panel, data
will be returned from the inverter. If the inverter number does not match, the data will
be judged invalid and no data will be returned.
Communication data will be invalidated and data will not be returned either if the in-
verter number does not match. (Inverter number is considered matched if it is omit-
ted during reception)
:'Y' (Block communication command [monitoring])
Lowercase letter 'y' during an inverter trip, including standing by for retrying and during
a trip.
: Return the number of data groups to be read (00H to 05H).
: Return 00H to 03H.
* Failing to write in the specified parameter in the number of write data groups, set "1"
in the corresponding bit for the parameter failed to write. (See below.)

Data Type
: Return according to the number of read data groups. "0000H" is returned as dummy
data if "0" is selected as a parameter.
