ASCII mode 

In ASCII mode, the frame head is “0x3A”, and default frame tail is “0x0D” or “0x0A”. The 
frame tail can also be configured by users. Except frame head and tail, other bytes will be 
sent as two ASCII characters, first sending higher nibble and then lower nibble. The data 
have 7/8 bits. “A”~“F” corresponds to the ASCII code of respective capital letter. LRC 
check is used. LRC is calculated by adding all the successive bytes of the message 
except the head and tail, discarding any carriers, and then two’s complementing the 
result. 
Example of Modbus data frame in ASCII mode:   
The command frame of writing 0x0003 into address “0x1000” of slave node address 1 is 
shown in the table below: 
LRC checksum = the complement of (01+06+10+00+0x00+0x03) = 0xE5

10.4 Protocol function 

Different respond delay can be set through drive’s parameters to adapt to different needs. 
For RTU mode, the respond delay should be no less than 3.5 bytes interval, and for 
ASCII mode, no less than 1ms. 
The main function of Modbus is to read and write parameters. The Modbus protocol 
supports the following commands: 

0x03 

Read inverter’s function parameter and status parameters 

0x06 

Write single function parameter or command parameter to inverter 

All drive’s function parameters, control and status parameters are mapped to Modbus 
R/W data address.   
The data addresses of each function parameters please refer the sixth column of chapter 
9.
