Data type is handled in hexadecimal notation and the transmission characters are treated with the
binary (HEX) code.
The transmission format is basically the same to the case of binary mode. S command is used and
the slave inverters do not return the data.

1)  INV-NO (1 byte)

: Inverter number

This is always excluded at the master inverter side at time of inter-drive communication, and
can be added when the user utilize this data for the purpose of proportional operation.
(When this code is added, only the inverter concerned will accept the data.)

2)  CMD (1 byte)

: Command

53H(“S”) or 73(“s”) command ... command for inter-drive communication
When the master inverter is not tripping, this will be 53H(“S”).
When the master inverter is tripping, this will be 73H(“s”).

3)  Communication number (2 bytes)

:

Communication number of frequency command (FA01).

4)  DATA (2 bytes)

: Data of frequency command value.

(0000H to FFFFH (no range check))

As for the S command, see section 4.2 “Commands”, and see chapter “6 Inter-drive communication function” for the
communication of inverters.
