signal to terminal “S1” (short circuit the “S1” terminal to “COM”) and stop the
motor by disconnecting the terminal “S1” from terminal “COM”. You can
start the motor reverse direction by connecting the terminal “S2” to “COM”
and stop the motor by disconnecting the terminal “S2” from terminal “COM”.
You can change the motor speed by adjusting the voltage on terminal “AIN”.
3) Control with Preset multi-stage value: Based on the default parameter setup,
you need to change the main set value source to preset multi-stage value
(P00.11=11) and keep the function of terminals “S3”and“PI” as default
(P02.07 = 22, P02.08 = 23), and set the preset values in parameters
P00.30~P00.37 to the speeds you expect. Then you can change the motor
speed to preset value by changing the logic status of terminals “S3” and “PI”.
6.3 Reset the parameters to Factory Defaults
1) Set parameter P07.00 = 9;
2) Power down the product fully and power on again, the keypad shows A.01
3) Press the “STOP” key to clear the A.01, then the parameters are reset to
factory defaults except for the parameter group 8 and group 9.
6.4 Reset the Faults (Alarms)
For non-locked faults, press “STOP” key to reset the fault.
For locked faults:
If parameter P05.30 = 0, press “STOP” to reset the fault;
If parameter P05.30 =1, you need to power down and power on first, then press
“STOP” key to reset the fault.
You can also set a digital input terminal function to reset fault (set one of the
parameters from P02.05 to P02.08 equals 1), and use digital input signal to reset
the fault.
6.5 Motor Parameters Auto Tuning
1) Correct motor parameters help to ensure the control performance. Motor
parameter auto tuning function can identify the motor parameters
(parameters from P01.14 to P01.27) automatically. If you did not run the
motor parameter auto tuning operation, the control will use default motor
parameters or use the parameters you set manually.
2) Ensure the motor is standstill
3) Set Parameters from P01.02 to P01.07 as the nameplate of the motor
4) Set parameter P01.13 to value 1 or 2 or 3 or 4 or 5 depending on your
demands (Refer to description of parameter P01.13 in 3.3.2). After you
confirm the parameter P01.13 value, the keypad will show “PUSH” “RUN”.
50
Then press the “RUN” key, the product starts the motor parameter auto
tuning function
Wait the until the keypad shows “PUSH” “Ent”, then press the “ENTER” key. The
motor parameter auto tuning function finished and the motor parameters are
updated.

10. Modbus Communication Guidance
The M313 drive provide RS485 communication interface. It adopts international
standard Modbus communication protocol to perform master-slave
communication. The user can realize centralized control through PC/PLC to
adapt specific application requirements.
10.1 Application Mode
10.1.1 Interface Mode
The communication interface is RS485. RS485 works on semi duplex and its data
signal applies differential transmission which is called balance transmission too.
10.1.2 Networking Mode
The drive has two networking modes: single master/multiple slaves networking
and single master/single slave networking.
Single master/single slave networking diagram
Single master/multiple slaves networking diagram
Specification:
1) No matter which mode, the drive is used as a slave in communication. When
master sends commands using broadcast address, the slave does not
respond;
2) It is recommended to use shield cables in multiple connection. The basic
parameter of the devices, such as baud rate and digital check bit in RS485
should be the same as slave device’s and there should be no repeated
addresses in slave devices.
83
10.2 Protocol Format
Modbus protocol only support RTU mode.
RTU data frame format is shown as the figure below:
Specification:
Start At least 3.5 idle characters
Slave address Address：0-127(0 is broadcast address)
Function code Modbus function code
Data (N-1)
Data (N 2 * N data -2)
…
Data 0
CRC CHK high-8-bit CRC check
CRC CHK low-8-bit
End at least 3.5 idle characters
10.3 Function Code
Function code supported by M313 drive Modbus protocol are as shown in the
table below:
Function code Description Meaning
0x03 Read Holding
Registers
Read drive functional parameters and
running status parameters
0x06 Preset Single

10.4 Register Address Definition
All the following register addresses are started from 0.
10.4.1 The Rules of Register Address of the Parameter Number
The parameters can be mapping to register address. The rules of register address
of the parameter number are shown below:
Register address = PNU – 1
For example: The register address of P00.30 is 30 - 1 = 29 (0x001D)
The register address of P09.11 is 911 - 1 = 910(0x038E)
Attention: Parameters Group 8 and 9 are Read-only.
The Drive don’t support write or read multiple parameters at a time.
10.4.2 Other Register Addresses Specification
In addition to parameter is mapped to Modbus registers, there are some
additional registers within the drive which can be used to control the drive,
monitor the drive's status. These registers can support write or read maximum 10
registers at a time.

* Reg. 10000 specification
When using communication to control the drive, you can set the frequency
directly by writing register 10000 . The register value is in the range of 0.00 ~
P05.08, unit 0.01Hz.

Bit 15~12 Reserved
* Reg. 10100specification
86
Register 10100 is used to read the drive warning/alarm code. For example: When
the drive occurs A.48 alarm, the value of register 10100 is 48. When the drive
occurs u.24 warning, the value of register 10100 is 24.
10.5 Communication ratio values
The Communication data is expressed by hexadecimal in actual application and
there is no radix point in hexadecimal. For example, if you want to set P05.08 =
61.5, 61.5 can be magnified by 10 times into 615. So hex 0x0267 (615) can be used
to express 61.5.
A non-integer can be timed by a multiple to get an integer and the integer can
be called communication ratio values.
The communication ratio values are referred to the radix point of the setting range
of default value in the functional parameter list. If there are radix point n, then the
communication ratio value m is 10^n.
10.6 Error message
There may be errors in the communication process, for example, some parameters
are read-only, but the PC/PLC sends a written directive, the drive will return an
error message.
Error message data frame format is shown as the figure below:
Error message function code = requirements function code + 0x80
Error code Specification
0x01 Function code error, the drive does not support this kind of
function code.
0x02 The register address is invalid.
0x03 The value exceeds the upper limit of the parameter
0x04 Operation error.

10.8 Debugging
Most customers use specialized or packed communication app or function
afforded by the supplier of PLC or touch screen. when there is communication
failure, it’s difficult to judge whether it’s the host’s issue or the frequency
converter’s issue. In this case, you can use the PC software tool like “serial
debugging assistant” (which is free to download from internet) to help the
diagnosis.
First please connect the system as blow figure. Normally a PC does not have RS485
port, you can use a transfer module to connect the PC. With the PC SW tool like
“serial debugging assistant”, you can monitor the details of the message sent from
the host and the message replied from the frequency converter.
