9.4.5 Data address definition
This section describes the address definition of communication data. The addresses are used for
controlling the running, obtaining the state information, and setting related function parameters of the
inverter.
9.4.5.1 Function code address representation rules
The address of a function code consists of two bytes, with the MSB on the left and LSB on the right.
The MSB ranges from 00 to ffH, and the LSB also ranges from 00 to ffH. The MSB is the hexadecimal
form of the group number before the dot mark, and LSB is that of the number behind the dot mark.
