9.4.4 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 VFD.
9.4.4.1 Function code address format rules
The address of a function code consists of two bytes, with the high-order byte on the left and
low-order byte 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 05. Therefore, the
function code address is 0506H in the hexadecimal form. For P10.01, the parameter address
is 0A01H.

Note:

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 regardless of the VFD status. Pay attention to the setting range, unit, and
description of a parameter when modifying it.
