SAFETY PRECAUTIONS
Always follow safety precautions to prevent accidents and potential hazards from
occurring.
In this manual, safety messages are classified as follows:
WARNING
CAUTION
Throughout this manual we use the following two illustrations to make you aware
of safety considerations:
Identifies potential hazards under certain conditions
Read the message and follow the instructions carefully.
Identifies shock hazards under certain conditions
Particular attention should be directed because dangerous voltage may be
present.
Keep operating instructions handy for quick reference.
Read this manual carefully to maximize the performance of LS485/Modbus-
RTU/Metasys-N2 for SV-iP5A series inverters and ensure its safe use.
CAUTION
Be cautious, when handling the CMOS components of the Option Board.
Static may lead to malfunctioning of the product.
Turn off the inverter power, when changing the communication cable.
Otherwise, you may damage the board or a communication error may occur.
Make sure to insert the Option Board connector to the inverter precisely.
Otherwise, you may damage the board or a communication error may occur.
Check the parameter unit before setting up the parameter.
Otherwise, a communication error may occur.
Improper operation may result in serious personal injury or
death.
Improper operation may result in slight to medium personal
injury or property damage.

1. Introduction
This instruction manual describes about specification and how to set up the RS485 option board for SV-
iP5A drive to communicate with PLC or PC. SV-iP5A series drive can be controlled and monitored by
PLC , PC and other master module with RS485 option board.
1.1 Features
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. It is possible to communicate with computer which has
built-in type of RS232 card. 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.
1.2 Before Installation
Before installation and operation, this manual should be read thoroughly. If not, it could cause personal
injury or damage other equipment.

3.4 Communication Protocol Selection (LS485/Modbus-RTU/Metasys-N2)
Setting 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 LS485 protocol is selected when the No.1 is OFF. SV-
iP5A series have the same setting.
(At this time the On/Off status of the No.3, 4 DIP switches has not an effect on the protocol
selection.)

Drives), the communication is resumed automatically in case of adjusting the DIP switch on the
option card in accordance with the master’s protocol.

4. Installation
4.1 Installing RS485 Option Board and Parameter setting
①Connect RS485 Option Board connector to the option connector inside the inverter control board.
(See Figure 3, 4). Make sure that the support is well connected. if the position of the support is not
right, it means that the option card is not connected correctly.
②Power up the inverter after verifying the option card is installed properly.
③When powering up the inverter, CPU LED is blinking per second after all LEDs blink one after
another.
④If “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.
⑤Check displayed < COM-01 > for SV-iP5A is set to RS485.
⑥Set the parameters as below when the above steps are all done.

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.
