Goodrive300 Series VFD Communication protocol

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.
10.4.5.2 The address instruction of other function 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.
