3.1 Precautions
（1）Install a middle breaker between inverter and power supply avoiding enlarging
accident.
（2）For reducing electromagnetic interface (EMI), please connect surge absorber to
coil of electromagnetic contactors, relays etc.
（3）Freq setting terminal AI, instrument circuit（AO）etc., these analog signals wire
should be over 0.3mm² shield wire. Shield layer is connected with ground terminal CM
less than 30m.
（4）Wiring of relay input and output loop (X1 ~ X3) should choose over 0.75mm²
intertwist or shield wire. Shield layer should be connected to control terminal CM less than
50m.
（5）Separate control wire from main loop wire, parallel wiring should be part over
10cm, and across wiring should be vertical.
（6）Wire of Inverter and motor should be less than 30m. When it is over 30m, it
should decrease inverter carrier wave freq properly.
（7）All down-lead should be tightened with terminals to ensure well-contact.
（8）Compressive resistance of all down-lead should match with inverter volt.
¾ Inverter output terminal U、V、W should not add absorber capacitor or other
RC absorber shown as fig.3-1.

AppendixⅠ：RS485 COMMUNICATION PROTOCOL
1.1 Summary
E300 series derivative models, E300B series supports standard RS485 communication
interface through PC/PLC to reach centralized monitor（send operation order, set inverter
running parameter and read inverter running state） to meet special using requirement. This
protocol is design for above function.
1.1.1 Protocol Content
This serial communication protocol defines transmission information and use format and it
includes master-polling (or broadcasting) format, master coding method. Content includes
function code of action, transferring data and error check. Slave response is the same
structure, and it includes action confirmation, returning data and error check etc. If slave
causes any error while receiving information or cannot finish action by master, it will send
one fault signal to master as a response.
1.1.2 Using Application
1. Suitable product
The protocol is suitable for all Sunfar product series ranges inverter（C300 series, C320
series, E350 series, E380 series, E300 series etc.）, which also can be suitable for
communication protocol of some other inverter brands.
2. Suitable mode
（1） Inverter connects to PC/PLC control net of “single master multi-slave” with RS485.
（2） Inverter connects to PC/PLC monitor background of “point to point” with RS485/
RS232 (transition interface).
1.2 BUS Structure and Protocol Description
1.2.1 BUS structure
1. Interface mode
RS485（RS232 for choice, but need level translator）
2. Transmission mode
Asynchronism serial and semiduplex transmission mode. At the same time, only master or
only slave can send data, and the other only can receive data. Data during serial
Asynchronism communication, it would send by a frame to a frame as form of message.
3. Topological mode
In single-master system, there are 32 sites at most, one as master site and 31 slave sites.
The setting range of slave address is 0~30, 31 (1FH) is broadcast communication address.
Slave address must be exclusive in the network. Point to point mode is a special
application as single master and multi-slaves topological mode, which is only one slave
condition.
1.2.2 Protocol description
RS485 communication protocol is a kind of serial master-slave communication protocol,
and only an equipment as master can build protocol in network (named as
“Inquire/Command”). Other equipments as slaves only can provide data to correspond
master “Inquire/Command” or corresponding action for master’s “Inquiry/Command”.
E300 Series Mini-type Integrated Universal Inverter Manual
SUNFAR E300 SERIES
26
Master is PC, industrial machine or programmable controller etc, and slave is inverter.
Master not only visits some slave, but also sends broadcast information to all slaves. For
single master “Inquiry/Command”, all slaves will return a signal as response; for broadcast
information provided by master, slave no need offer any feedback to master.
1．Data structure
Three kinds of data transmission for choice：
（1）1 bit start-bit, 8 bit data bits, 1 bit stop-bit and no check bit.
（2）1 bit start-bit, 8 bit data bits, 1 bit stop-bit and even check bit（manufacturing
setting）.
（3）1 bit start-bit, 8 bit data bits, 1 bit stop-bit and odd check bit.
2．Baud rate
Five baud rate for choice: 1200bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps
3．Communication mode
（1）Adopt master “poll”, slave “response” point to point communication.
（2）Use inverter keypad sets inverter serial interface communication parameter, including
local address, baud rate and data format.
Master set must be same as inverter baud rate and data format.
4．Communication rule
（1） There are at least 5-byte startup interval time between data frames, only the
message with stated startup internal time is valid.
（2） Mater waiting time and inverter longest corresponding time is 8-byte transmission
time. If longer time, judge as communication failure.
（3） If inverter does not receive any message after communication overtime checkout
time (function code: F4.4）, judge as wire-break. Then, based on communication
auxiliary function setting (function code: F4.3), it decides slave running state. (If
receive any message during this time, it will control under it.)
1.2.3 Message structure
Length of each message is between 11～18 bytes（based on data format）,Character type
can be ASC code and hex.Ⅱ
Data showing rule: hex, high number before and low number after. Shown as bellow:

5AH, all data behind header is hex code and invalid byte fill 0. Unaided headers of 2AH
and 5AH aren’t rightful header. There need waiting time above five bytes before sending
header.
Set range of inverter address：0～30，31（1FH）as broadcast communication address.

Appendix BRAKING RESISTORⅢ
During inverter running, if speed of controlled motor decreases too fast or shock of motor
load too fast, its feedback energy may generate power into inverter capacitance that
would cause damage of inverter itself. Inverter inner control will restrict based on load. If
braking performance can not reach requirement, it needs external braking resistor to
achieve energy release in time. External braking resistor as energy consuming mode
would consume for power braking resistor. If so, power of braking resistor should select
suitably. Below is SUNFAR recommended braking resistor power and resistor value.
Based on load situation, user can select suitable value for SUNFAR inverter requirement.
Inverter model
E300-2S0002
E300-2S0004 0.4 0.1 150 100
E300-2S0007 0.75 0.1 100 100
E300-2S0015 1.5 0.2 70 100
E300-4T0007 0.75 0.1 400 100
E300-4T0015 1.5 0.2 300 100
Above recommendation is for 100% braking torque. If braking is not visible, please
decrease braking resistor and increase braking resistor power class.
Braking resistor power is estimated value during braking resistor interval running
situation. When braking resistor lasts long time work（above 5s）, it should
increase braking resistor power class properly under same resistor value.
