(viii) 07 command: This command writes data to a specified setting item in the inverter.
- Transmission frame
Frame format
STX Station No. Command Parameter Data BCC CR
Description Data size Setting
STX Control code (Start of TeXt) 1 byte STX (0x02)
Station No.
Station number of control-target
inverter
2 bytes 01 to 32, or FF (broadcast to all stations)
Command Command to be transmitted 2 bytes 07
Parameter Data parameter number 4 bytes See Note 14.
Data
Parameter data (decimal ASCII
code)
8 bytes See Note 13.
BCC Block check code 2 bytes
XOR of the items from "Station No." to "Data."
See Item (3) of this section.
CR Control code (Carriage Return) 1 byte CR (0x0D)
Note 14: Possible range of parameters is as follows.
F002-, A001-, b001-, C001-, H001-, P001- (F001 is written with 01 command.)
- Response frame
Positive response: See Item (2)-(i) of this section.
Negative response: See Item (2)-(ii) of this section.
(ix) 08 command: This command initializes specified settings in the inverter.
The setting items to be initialized follow the setting of the initialization mode (b084). When "b084" is "00",
the trip history data is cleared.
