Note: P29 group is the factory parameter which can not be read or changed. Some parameters can 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.
7.4.2 The address instruction of other function in Modbus
The master can operate on the parameters of the inverter as well as control the inverter, such as running or
stopping and monitoring the working state of the inverter.
