Note: section 10.2 and 10.3 mainly describe the command format, and the detailed application will be mentioned
in 10.8 with examples.
7.3.3 Command code 08H for diagnosis
Meaning of sub-function codes
Sub-function Code
For example: The inquiry information string is same as the response information string when the loop detection to
address 01H of driver is carried out.
The RTU request command is:
START
ADDR
CMD
High byte of sub-function code
Low byte of sub-function code
High byte of data content
Low byte of data content
Low byte of CRC
High byte of CRC
END
The RTU response command is:
START
ADDR
CMD
High byte of sub-function code
Low byte of sub-function code
High byte of data content
Low byte of data content
Low byte of CRC
High byte of CRC
END
7.3.4 The definition of data address
The address definition of the communication data in this part is to control the running of the inverter and get the
state information and relative function parameters of the inverter.
START
