I-3 Definition of communication parameter address
The section is about communication contents, it’s used to control the operation, status and
related parameter settings of the inverter. Read and write function-code parameters (Some
functional code is not changed, only for the manufacturer use or monitoring): the rules of labeling
function code parameters address:
The group number and label number of function code is used to indicate the parameter address:
High byte: F0 to FB (F group), A0 to AF (E group), B0 to BF(B group),C0 to C7(Y group),70
to 7F (d group) low byte: 00 to FF, this should be written EPPROM.
For example: address F3.12 indicates F30C; Note: L0 group parameters: neither read nor
change; d group parameters: only read, not change.
