■ VF-S11 → computer (binary mode)
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 invalid and
no data will be returned.
: Command...The command is also used for a check when the inverter is tripped.
Under normal conditions...52H (R), 47H (G), 57H (W) or 50H (P) is returned, depending on
the command received.
When the inverter is tripped...The lowercase letter 72H (r), 67H (g), 77H (w) or 70H (p) is
returned with 20H added to it, depending on the command received.
: The communication number received is returned.
: Data ... 0000H to FFFFFH
The data read is returned for the 52H (R) and 47H (G) commands, while the data written is
returned for the 57H (W) and 50H (P) commands.
