V5 series inverter
93
START Keep no signal input > =10ms
Address Communication address: 8-bit binary address
Function Function code: 8-bit binary address
DATA (n - 1)
Data:
N*8-bit data, N< =8, Max=8 bit
……………
DATA 0
CRC CHK Low CRC parity code
CRC CHK High 16-bit CRC parity code is combined by 2 8-bit binary value
END Keep no signal I/O > =10ms
2. Communication address:
00H: broadcast for all the inverters（broadcast）
01H: communicate with the inverter addressed 01
0FH: communicate with the inverter addressed 15
10H: communicate with the inverter addressed 16
………., max can reach 254（FEH）
3. Function code and Data:
Function code Explanation
03H Read register, read multi-register once (register less than 31), can read the same group of data every
time
06H Write data to register
08H Circuit test
10H Write multi-group data to register
(1) Function code 03H: read register
For example: Read address 2104H (Output current）
