Definition of communication parameter address
Read and write function-code parameters (Some functional code is not changed, only for the manufacturer use.)
The group number and mark of function code is the parameter address for indicating the rules.
High level bytes: Group A0~AF(GroupA0-A2/ Groupb0-bC), Groupb0-bF(Group C0-C6/Groupd0-d6),
70-7F(Group U)
Low level bytes: 00 to FF
For example: b0-03, address indicates to 0xA303.
Note:
Group U: Only for reading parameter, cannot be changed parameters, some parameters cannot be changed
during operation, some parameters regardless of what kind of state the inverter in, the parameters cannot be
changed. Change the function code parameters, pay attention to the scope of the parameters, units, and relative
instructions.

Besides, due to EEPROM be frequently stored, it will reduce the lifetime of EEPROM. In the communication
mode, and some function codes don’t have to be stored as long as change the RAM value.
