Transmission Format For Inter-Drive Communication - Toshiba Tosvert VF-S15 Series Instruction Manual

6.2. Transmission format for inter-drive communication

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.
 Master inverter → Slave inverter (Binary mode)
Omissible
(3.5bytes "/" INV-NO
Blank) (2FH) 1 byte
1) INV-NO (1 byte) : Inverter number
2) CMD (1 byte) : Command
3) Communication number (2 bytes)
4) DATA (2 bytes) : Instruction data to slave (0 to 10000:100=1%)
As for the S command, see "4.2. Commands", and see "6. Inter-drive communication function" for the communication
of inverters.

Checksum area
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.)
53H ("S") or 73H ("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").
