parameters cannot be changed whether the frequency converter is in whatever state; when changing the
function code parameter, the parameter’s range, unit and related explanations should also be paid attention.

Note: since EEPROM is frequently restored, so the service life of EEPROM shall be reduced, therefore,
some function codes have no need to be stored under the communication mode, if only the value in the
RAM modified.
If it is the Group F parameter, whether only the high position F for the function code address changes to 0,
then the function can be achieved.
If it is the Group A parameter, whether only the high position A for the function code address changes to 4,
then the function can be achieved.
The corresponding function code address is shown as below:
High byte: 00~0F(Group F)
、
40~4F(Group A)
Low byte: 00~FF
For example:
If function code F3-12 is not stored in EEPROM, then the address is shown as 030C;
If function code A0-05 is not stored in EEPROM, then the address is shown as 4005;
The address presentation can only act the writing RAM, without acting the reading action. When reading, it
is the invalid address.
As for all the parameters, command code 07H can also be used for realizing the function.
