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. 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 P10.01, the parameter address is 0A01H.

Note:
1. The parameters in the P99 group are set by the manufacturer. They cannot be read or
modified. Some parameters cannot be modified when the VFD is running; some cannot be
modified regardless of the state of the VFD. Pay attention to the setting range, unit, and
related description of a parameter when modifying it.
2. The service life of the Electrically Erasable Programmable Read-Only Memory (EEPROM)
may be reduced if it is frequently used for storage. For users, some function codes do not
need to be stored during communication. The application requirements can be met by
modifying the value of the on-chip RAM, that is, modifying the MSB of the corresponding
function code address from 0 to 1. For example, if P00.07 is not to be stored in the
EEPROM, you need only to modify the value of the RAM, that is, set the address to 8007H.
The address can be used only for writing data to the on-chip RAM, and it is invalid when
used for reading data.
9.4.5.2 Description of other function code addresses
In addition to modifying the parameters of the VFD, the master can also control the VFD, such
as start and stop it, and monitor the operation state of the VFD. The following table describes
other function parameters.
