Note:

P29 group is the factory parameter which cannot be read or changed. Some parameters
cannot be changed when the VFD is in the running state and some parameters cannot be
changed in any state. The setting range, unit and related 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 MSB 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.
7.4.2 Description of other function addresses in Modbus
The master can operate on the parameters of the VFD as well as control the VFD, such as
running or stopping and monitoring the working state of the VFD.
