safe use.
CAUTION
zDo not touch the CMOS components unless the board is grounded.
Otherwise, ESD could cause break down of CMOS components.
zDo not change the communication cable when the inverter power is turned on.
Otherwise, there is a danger of connecting error and damage to the board.
zMake sure to precisely insert the connector of inverter and option board
Otherwise, there is a danger of connecting error and damage to the board.

2.1.
SV-iP5A/iV5 inverter can be controlled and monitored by the sequence program of the PLC or other
master module. The option card provides a terminal block for an RS-485/Modbus-RTU interface. Drives or
other slave devices may be connected in a multi-drop fashion on the RS-485/Modbus-RTU network and
may be monitored or controlled by a single PLC or PC.
Inverter can be easily applicable to Factory Automation because operation and monitoring is available by
User-program.
* Parameter setting and monitoring is available via computer.
(Ex: Freq. Command, Run/Stop etc.)
* Interface type of RS485 reference:
1) Allows the drive to communicate with any other computers.
2) Allows one computer to control up to 31 drives with multi-drop link system.
3) Noise-resistant interface.
Users can use any kind of RS232/485 converters. The specifications and performances of converters
depend on the manufacturers, but the basic functions are the same. Refer to the converter manual for
detailed specifications and instructions on how to use.
Before Installation
Before installation and operation, this manual should be read thoroughly. If not, it could cause personal
injury or damage other equipment.

INSTALLATION
Installing RS485/Modbus-RTU card
① Connect RS485/Modbus-RTU communication card connector to the option connector inside the
inverter control board. (See Figure 1, 2). Make sure that the support is well connected. Is the
position of the support is not right, it means that the option card is not connected right.
② Power up the inverter after verifying the option card is installed properly.
③ When powering up the inverter, CPU LED is blinking per second after all LEDs blink one after
another.
④ If “CPU LED” is not blinking, power down the inverter swiftly and check for the proper installation of
the option card.
(Caution: The inverter and option card may get damaged in case that power is applied to the
inverter for a long time when CPU LED is not blinking.)
* If this problem occurs continuously, contact LS distributors.
⑤ Check displayed < COM-01 > for SV-iP5A and < EXT_01 > for SV-iV5 are set to RS485.
⑥ Set the parameters as below when the above steps are all done.

note3) It is used for Emergency Stop when communication between inverter and Master is not done
properly. It is activated when communication is not done even once for the set time. It indicates the
inverter is not controlled by Remote. Set this value for safety.
⑦ Power down the inverter for the connection of converter when step○
6is finished.
⑧ If the inverter is to be placed at the end of the network trunk line, install a jumper on the option card
to enable the termination resistor (120 Ω). (See the Figure 3).

S : Use only one point in the whole network lines for grounding.
Connect to the screw next to the shield terminal when grounding through the inverter.
GND : Ground of communication terminal.
T1, T2 : If the option card is installed within the inverter which is to be placed at the end of the
network trunk line, short terminals T1 and T2. This allows the internal termination resistor
(120Ω) to be connected.
4.3.3. Communication Protocol Selection (RS485/Modbus-RTU)
zSetting method
The Modbus-RTU protocol is selected when the No.1(among the DIP switches located on the lower
right corner of the option card) is ON, and RS485 protocol is selected when the No.1 is OFF. That’s
the same for both SV-iP5A, SV-iV5.
(At this time the On/Off status of the No.2, 3, 4 DIP switches has not an effect on the protocol
selection.)

PARAMETER CODE (All parameter addresses are Hex values)
<Common Area> : Common Area is addresses to be used commonly regardless of inverter models. Some
addresses are used only for specific inverter models. note5)
note5) When the data is changed by Common Area parameter, its data is not saved.
That is, the changed data is effective in the present state but the data is reset to the previous value after
the inverter is reset or powered On / Off.
Even though the inverter is reset or powered On / Off, the changed data is effective in case of changing
the data by each group parameter, not the Common Area.

note6) Because other series (iS5, iG5, etc.) use addresses 0x0007 and 0x0008 for the Acceleration &
Deceleration Time in Device Net, same addresses are used for iV5. Besides Device Net,
Acceleration & Deceleration Time of addresses 0x0503 and 0x0504 may be used for SV-iV5.
note7) Hz is used for the motor speed feedback, only when communicating via Device Net.
note8) Indicates that the inverter is at a state of operating without trip. Indicates ‘1’ before, during, after
operation, when there is no trip.
note9) Indicates
‘ 0 ’when at stop (bit0= ‘ 1 ’ ), ‘1 ’ when at forward run (bit1= ‘ 1 ’ ), ‘ 0 ’ at reverse run (bit2= ‘ 1 ’ )

18
When it is not connected right, it indicates ‘0 ’ when at forward run (bit1= ‘ 1 ’ ), ‘ 1 ’ at reverse run
(bit2=
‘ 1 ’ )
note10) The relationship between Bit10 Forward Command, Bit11 Reverse Command, Bit01 Forward
Run(FX), and Bit02 Reverse Run(RX) are as follows. Bit10, Bit11 indicate information of the
present run command and Bit01, Bit02 indicate the present operation status. For example, if stop
command is put in while running forward, Bit11 Forward Command would be ‘0,’ but Bit01
Forward Run (FX) would be ‘1
’when decelerating and be ‘ 0 ’after it stops .
When Reverse Run command is put in, while running forward at a speed of 1800 RPM, Bit11
Reverse command and Bit01 Forward Run (FX) remain ‘1’ until the rotating direction of the motor
changes, decelerating from 1800 RPM.
note11) Indicates ‘1,’ when CON_20 Proc PID Enb(0x7514) is set to Enable(
‘ 1 ’ ) and when it’s running
(bit13=
‘ 1 ’ ). It indicates ‘0’ at stop.
note12) For SV-iV5, both positive and negative direction speed get indicated. For the positive direction
speed, if it is 1800 RPM, it gets indicated as 0708h and 1800 as decimal number. For the
negative direction speed, if it is -1800 RPM, it gets indicated as F8F7h. This negative number is
expressed as 1’s complement and the absolute value gets calculated as below.
(FFFFh – F8F7h) (10) = 0708h(10) = 1800
A negative sign gets in front of this absolute value and -1800RPM is the end result.
The calculation of the negative speed is as below.
Speed (RPM) = (FFFFh – FXXXh(received negative speed data))(10) × (-1)
note13) When communicating via Device Net, speed command is given with Hz.
note14) Checks up with the PostRamp Ref value during run. Speed is displayed by absolute value.
note15) Checks up with the PreRamp Ref value during run. Indicate speed by classifying signs and refer
to note11.
note16) Checks up with the DIS_01’s Torque Ref value during run. Calculate with 2’s complement since
negative torque value comes out during reverse run.
ex) When the read value is FE0Ch, it gets calculated as follows.
Torque(%)=(FFFFh-FE0Ch + 0001h)(10) × (-1)
=(01F3h + 0001h)(10) × (-1)
=(01F4h)
(10) × (-1)
=-500
It is –50% since the unit is 0.1%
The formula would be,
Torque (%) = (FFFFh – FXXXh (received negative torque data) + 0001h)(10) × (-1)
note17) Default DISPLAY checks up as Tq. For the calculation, refer to note15.
note18) When CON_20 Proc PID Enb is set to Enable, read during run and save the value of 0x050B PID
input command. DIS_04 Process PID output checks up at Ref/FB’s Process PID command value.
It reads and saves the value of 0x050B PID input command only during run, so in case of chaged
value of the 0x050B PID input command at stop, you’ll still be able to know the former command
value through the 0x0024 PID Reference value. In this case, a value other than the DIS_04’s
Process PID command value gets saved and saves the same DIS_04’s Process PID command

19
value after reading the value from 0x050B when starting Run.
note19) When CON_20 Proc PID Enb is set to Enable, it checks up with DIS_04 Process PID output
Ref/FB’s Process PID F/B value.
note20) When CON_20 Proc PID Enb is set to Enable, it checks up with DIS_04 Process PID output
Ref/FB’s Process PID output value.
