I.5 Communication parameter address
The chapter is about communication
contents, it’s used to control the inverter operation, the
status of the inverter and related parameter setup. Read and write functioncode parameters
(Some function codesare not able to be changed, only for the manufacturer use.). The mark
rules of function code parameters address
：
The group number and mark of function codesare parameter address for indication rules.
High byte
：
F0~FF(P group), A0~AF(A group), 70~F(U group)Low byte
：
00~FF
For example
：
P3.12, the address indicates F30C
Caution
：
Group PF
：
Parameters could not be read or be modified.
Group U
：
Parameters could be read but not be modified.
Some parameters can not be changed during operation, some parameters regardless of
the kind of state the inverter in, the parameters can not be changed. Change the function code
parameters, pay attention to the scope of the parameters, units, and relative instructions.
Besides, if EEPROM is frequently stored, it will reduce the service life of EEPROM. In some
communication mode, function code need to be stored as long as changing the RAM value.
Group P
：
to achieve this function, change high order F of the function code address into 0.
Group A
：
to achieve this function, change high order A of the function code address to be 4.
Corresponding function code address are indicated below
：
High byte
：
00~0F(P group), 40~4F(A group)Low byte
：
00~FF
For example
：
Function code P3.12 can not be stored into EEPROM, address indicates to be
030C,function code A0-05 can not be stored in EEPROM, address indicates to be 4005
；
This
address can only act writing RAM, it can not act reading, when act reading, it is invalid address.
For all parameters, command code 07H can be used to achieve this function.
