USER MANUAL
Before Installing
Fnet OPTION BOARD
This manual describes about the installation, operation, and precautions of Fnet board
SV-iS5
Series
of iS5 series. Read the manual and precautions thoroughly before installation and
operation. If not, it may cause break down of board and shorten the product life.
! C
Do not install the option board when the power is introduced. If not, both of the
inverter and option board may be broke down. (Attach and detach the option
board to the inverter control board after the capacitor discharged)
ESD can cause break down of CMOS components. Do not touch the CMOS
components without the board is grounded.
Do not change the communication cable with the inverter power is turned on.
Make sure to precisely insert the connector of inverter and option board
Make sure the connection of signal wire (P, N). P signal wire must be connected
to the P terminal.
Connect terminal resistor at the last connected option board of 110 ohm, 1/2
watt. (refer to Figure 6)
Check the parameter unit when setting the parameters.
1. Introduction
Fnet board provides control and monitoring of iS5 series inverter for GLOFA PLC via
high-speed serial communication. The communication protocol is programmed with
GLOFA PLC.
1.1. Benefits of using Fnet board
It is possible to control the inverter with high-speed communication of 1M BPS.
Easy installation and change of a system because the control and monitoring of
inverter is accomplished by PLC programming.
Multiple inverters can be connected only with 2 line wires, providing time saving
and easy maintenance.
Easy system integration by using PLC related devices.
1.2. Contents included
Fnet option consists 1 Fnet board, 2 connectors, 3 supporters, and manual.

2.2. Installing on Inverter Board
Unscrew the crews that fasten the inverter board and install the copper
supporters proveded.
Install the Fnet board by inserting the connector of inverter and Fnet board and
tighten the screws that unscrewed from the inverter board.

5. Operating
5.1. Power On Test
Turn on the inverter power after installing the option boar, and then inverter perform
Power On test.
First Op LED starts flickering and Err LED, Tx LED, Rx LEDs flickers at interval of 250ms.

5.2. Setting Inverter Parameter
Set inverter parameters described below using keypad.
5.2.1. Checking Option board [COM group/code# 01: PLC-GF]
This parameter checks the option board installed on inverter board. This code must
display "PLC-GF".
5.2.2. Setting Inverter Number [COM group/code# 17: 0 ~ 63]
This parameter sets the station number of inverter. Inverter number must match
the station number set in PLC. Setting a same number at more than one inverter
cause communication error.

None
Inverter is controlled by keypad or control terminal instead Fnet board.
Command
Inverter takes just run commands of Forward Run, Reverse Run, and Stop
from the Fnet board.
Freq
Inverter takes just frequency command from the Fnet board.
Cmd + Freq
Inverter takes all commands from the Fnet board.
5.2.4. Setting Lost Command [I/O group/code# 48]
This parameter set the actions of inverter ahead when the communication is
disconnected (timeout) by some reasons such like DPRAM error, cable cutting.
I/O▶ ▶ ▶ ▶ Lost command
48
None
<In case of "timeout" error >
None: Inverter keeps the command that just have before the disconnection
of communication.
FreeRun: Inverter stops with FreeRun (Coast to stop).
Stop: Inverter stops with the deceleration ramp set at FU1 # 06.
Terminal R
110Ω, 1/2W
5.2.5. Setting timeOut [I/O group/code# 49]
This Parameter sets the time that inverter decides disconnection of communication.
Inverter takes actions of Lost Command after this set time.
