LG SV-IS5 communication driver

LG SV-IS5 communication driver is the driver to communicate with inverter of LSIS Co., Ltd. in Korea.

1. Read Settings

<Figure 1> is read setting example of LG SV-IS5 communication driver.( LS BUS protocol )

<Figure 1>  Read setting example of LG SV-IS5 communication driver

Device part of  <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to controller.

Baud rate(1200,2400,4800,9600,19200bps), Parity bit(0, 1, 2), Data bit, Stop bit(1, 2) of SV-IS5 can set operation button of Inverter.

LG SV-IS5 communication driver read schedule

1) Station – 1 ~ 31 station number of inverter.

2) Read command – Command.

R – read of  common area data, ( ( refer to <table 1> , <Table 2> or manual of SV-IS5 )

Y – read of relay status(Digital Input) value. 

3) Read start address –  Address of SV-iS5. ( 0 ~ )

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – 1 ~ 8 read size.

Read schedule example)

READ,     1,     R,     0,    0,   8,

READ,     1,     R,     8,    8,   8,

<Table 1> is address range of each group data.

<Table 2> is address range and contents for common area.

Note) Please refer to manual of SV-IS5 for DRV, FU1, FU2, I/O, EXT, COM, APP, ...

 If you click the icon  in protocol option part, you can see the dialog box such as <Figure 2>. you can also set read schedule by using this part.

<Figure 2> Example of LG SV-IS5 communication driver’s Option dialog box

You can set read schedule by using , ,  button and listbox of <Figure 2>.

<Figure 3> Example of LG SV-IS5 communication driver’s read schedule Add/Edit dialog box

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> will be shown.

2. Writing settings

You can set LG SV-IS5 controller by using 'writing settings'. 

LG SV-IS5 controller can write only R/W address.

Digital write

Digital write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             1 ~ 31 station number of inverter.

3)  ADDRESS          writing address. ( hex-decimal unit )

W write command  : higher 3 digit – address of inverter,  lower 1 digit - 0 ~ F bit position,

X write command  : 4digit address to be registered,

X_FILE write command  : don't care. 

4)  Extra1                  write command.

W : Bit unit write command,

X : single data Address Monitor register,

X_FILE : multi data(max = 8) Address Monitor register, the setting data read at 'work folder\SCAN\monitor.ini' file. 

5) Extra2                   don't care.

Write example 1)

PORT:0,  station:1, ADDRESS:0061, Extra1:W,  Extra2 : 0

The setting parameter shown above is forward run(On/Off) control example of 1 SV-IS5 inverter.

Write example 2)

PORT:0,  station:1, ADDRESS:0012, Extra1:X,  Extra2 : 0

The setting parameter shown above is single data Address Monitor register example of 12 address.

Write example 3)

PORT:0,  station:1, ADDRESS:0000, Extra1:X_FILE,  Extra2 : 0

The setting parameter shown above is multi data Address Monitor register example. Setting register data read from 'work folder\SCAN\monitor.ini' file. 

<Figure 4> Example of Address Monitor register file

• Note) <Figure 4> is example of Address Monitor register file for 0x0001, 0x0006, 0x0007, 0x000C, 0x000D, 0x000F, 0x0011 7 address.
• You can read Address Monitor register data from Y read command, after X_FILE  write command.

Analog Write

Analog write and digital write have the same setting parameters except output value and address. ( address = 4 digit hex-decimal unit address of inverter )

Write example 1)

PORT:0,  station:1, ADDRESS:0007, Extra1:W,  Extra2 : 0

The setting parameter shown above is acceleration time setting example of 1 SV-IS5 inverter.

Write example 2)

PORT:0,  station:1, ADDRESS:0008, Extra1:W,  Extra2 : 0

The setting parameter shown above is deceleration time setting example of 1 SV-IS5 inverter.

3. Connection of communication cable and setting of station, baud rate

Connection of communication cable and setting of station, baud rate are as follows.

Connection of communication cable

Please connect 2, 3, 8 pin of 10pin socket and 3, 2, 5 pin of computer(RS-232C 9pin socket such as <Figure 5>.

 SV-IS5 inverter                                                  computer (9pin socket)

pin 2(up-right->2nd from left) ----------------------  pin 3

pin 3(up-right->3rd from left) ----------------------  pin 2

pin 8(up-right->8th from left) ----------------------  pin 5

Setting of station and baud rate

Station and baud rate of SV-IS5 inverter can set operation button of Inverter. ( refer to <Figure 6> )
