not be changed when the inverter is in the running state and some parameters can not be changed in
any state. The setting range, unit and relative instructions should be paid attention to when modifying
the function code parameters.
Besides, EEPROM is stocked frequently, which may shorten the usage time of EEPROM. For users,
some functions are not necessary to be stocked on the communication mode. The needs can be met
on by changing the value in RAM. Changing the high bit of the function code form 0 to 1 can also
realize the function. For example, the function code P00.07 is not stocked into EEPROM. Only by
changing the value in RAM can set the address to 8007H. This address can only be used in writing
RAM other than reading. If it is used to read, it is an invalid address.

The master can operate the parameters of the inverter as well as control the inverter, such as running
or stopping and monitoring the working state of the inverter.
