5. Description of Protocol Format
5.1 Address Code
Address of slave inverter. The setting range: 1~247, 0 is broadcast address.
5.2 Command Code
Command Code Function
03H Read parameters and status byte of inverter

5.3 Allocation of Register Addresses
Name Address Description
Function
Code
0000H～1F1FH
(Saving
Address)
High byte is the function code group number. F00～
F11, C0, E0, P0, and P1 are corresponding to high bytes:
00H～0BH, 10H, 11H, 12H, and 13H respectively.
Low byte is serial number of function code group. 0~31
corresponding to low bytes 00H~1FH. For example: the
corresponding saving address of F0-07 is 0007H.
2000H～3F1FH
(Temporary
Saving Address)
Frequent modification of EEPROM will reduce its
lifespan. Temporary saving is not required if only
editing the value of function code. To avoid EEPROM
damage, the address of function code+2000H. For
example, the temporary saving address of F0-07 is
2007H.
