The definition of communication data address:
：
This part is the address definition of communication data, and used to con-
trol the operation of the inverter, obtain inverter state information and rel-
ated function parameters settings,etc.
6.Function code parameter address rules
High and low byte range respectively: high byte F0
～
FE(F group),A0~A2(F15
~F17 group) ; low byte 00~FF. For example, if visit F04.02, so the function
code address is 0xF40C.
Note:
F14 group: manufactures setting parameters, neither can read this
group of parameter, nor change this group of parameters; F17 group: can
read this group of parameter,but can not change parameter.When inverter
is in operation, some parameters cannot be changed; some parameters
cannot be changed no matter what state the inverter is; when changing
the function code parameters, you also should note the parameter setting
range, units, and related instructions.

Because the EEPROM is frequently stored, it will reduce the service life of
EEPROM. As for users, some function code does not need to be stored un
-
der the mode of communication, and only need to change the value of
RAM to satisfy the usage requirements. This function can be achieved only
by changing the high-order of the corresponding code address from F to 0.
High and low byte range respectively: high byte 00
～
0F(F group); low byte
00
～
FF.
For example:
Function code F04.12 is not stored in the EEPROM, and set the address to
040C. Function code F15.51 is not stored in the EEPROM, and set the
address to 4033.
This address can only be used for chip RAM, and cannot used as a function
of reading, if doing so, then invalid address. For all parameter, it can realize
this function by command code 07H.
