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 status information, and setting function parameters of the VFD.
9.4.5.1 Function code address format rules
The address of a function code consists of two bytes, with the high-order bit on the left and low-order
bit on the right. The high-order bit ranges from 00 to ffH, and the low-order bit also ranges from 00 to
ffH. The high-order bit is the hexadecimal form of the group number before the dot mark, and low-
order bit is that of the number behind the dot mark. Take P05.06 as an example: The group number is
05, that is, the high-order bit of the parameter address is the hexadecimal form of 05; and the number
behind the dot mark is 06, that is, the low-order bit is the hexadecimal form of 06. Therefore, the
function code address is 0506H in the hexadecimal form. For example, the parameter address
ofP10.01 is 0A01H.

The parameters in the P99 group are set by the manufacturer and cannot be read or modified.
Some parameters cannot be modified when the VFD is running; some cannot be modified
