10.4.5 Data address definition
This section describes the address definition of communication data. The addresses are used for
controlling the running, obtaining the status information, and setting function parameters of the VFD.
10.4.5.1 Function code address format 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.
Take P05.06 as an example: The group number is 05, that is, the MSB of the parameter address is
the hexadecimal form of 05; and the number behind the dot mark is 06, that is, the LSB is the
hexadecimal form of 06. Therefore, the function code address is 0506H in the hexadecimal form. For
example, the parameter address of P10.01 is 0A01H.
