series frequency converter is a simple and smart frequency converter, which can control AC asynchronous
motor by V/F, and is suitable for simple places such as assembly line and fan. This manual introducesthe configuration
function and usage of series frequency converters.
Please understand the safety precautions before using this product. When using for the first time (installation,
operation, maintenance, inspection, etc.)
Please read this manual before series frequency converters. Equipment supporting manufacturers please send
this manual to the end user along with it for subsequent reference.
In order to illustrate the details of the product, the legends in this manual sometimes show the state of
removing the housing or safety cover.
When using this product, please be sure to install the shell or cover as required, and operate according
to the instructions.
The legend in this instruction manual is for illustration only and may differ from the product you ordered.
Due to product upgrade or specification change, and in order to improve the convenience and accuracy
of the manual, the contents of this manual will be changed in time.
If you need to order the instruction manual due to damage or loss, please contact our regional agents

6.1. 1 Format per byte in RTU mode
Chapter 6 Communication Protocol
(the following data are all hexadecimal)
6.1. 2 RTU data fra me sequence diagram
When the controller communicates on Modbus bus in RTU mode, every 8-bit byte in the information
is divided into 2 4-bit hexadecimal characters. The main advantage of this mode is that the density of
characters transmitted is higher than that of ASCII mode at the same baud rate, and each information
must be continuously transmitted.
Coding system: 8-bit binary, hexadecimal 0-9, A-F.
Data bit: 1 bit start bit, 8 bits of data (low bit first sent),
stop bit occupies 1 bit, parity bit can be selected.
(Refer to RTU data frame as sequence diagram)
