Meaning
0x0000 ~ 0x1A00
The corresponding relationship between the function codes of the inverter and the
Modbus protocol register address. The bytes at higher orders refer to the descriptions of
function code groupnumber. The bytes at lower orders refer to groupnumber, express
with HEX adecimal. P0 to PE, d0, d1, d2, H0

0x18. for example,the Modbus address of function code Pb.23 is
(0x0b<<8)+23=0x0b17
0x4000 ~ 0x5A00
The corresponding relationship between the function code attribute word (“attribute word”
means use odd number to describe even number) of the inverter and the Modbus
protocol register address. The bytes at higher orders refer to the function code group No.
plus 0x40, while the bytes at lower orders refer to serial No. in the group, for example,
0x4b17 corresponds to the attribute word of the function code Pb.23. The attribute words
are defined in the following order: Bit0 ~ Bit2 for unit, Bit3 ~ Bit4 for modifying attribute,
Bit5 ~ Bit6 for precision and Bit7 ~ Bit15 for reserved purpose.
0x8000 ~ 0x800D
The register for control word of the inverter. Refer to Attached Table 2 for details.
0x810B ~ 0x8193
The register for status word of the inverter. Refer to Attached Table 3 for details.
0xF000 ~ 0xF002
Special register for input password authentication. Refer to Attached Table 4 for details.
0xF080~ 0xF084
Read the current value, high limit, low limit, and factory default value of the function code,
and rewrite the function code. Refer to Attached Table 5for details.
Register for control word of the inverter.
