GS-EDRV(100) Ethernet Interface
3rd Ed, Rev B 10/2017
GS-EDRV Overview
The GS-EDRV provides a low-cost, high-performance 10BaseT Ethernet link
between a control system and a GS Series AC Drive. The control system can be
any of the following:
• DL205 CPU, DL405 CPU, or a WinPLC, with the appropriate Ethernet Remote
Master module (H2-ERM or H4-ERM).
• A Productivity3000 CPU using the onboard Ethernet port.
• A PC running Entivity’s ThinknDo software, a PC using a custom device driver that
was developed using our Ethernet SDK, or a PC running KEPDirect EBC or OPC
Server.
• Any independent I/O controller with a Modbus TCP/IP driver.
The GS-EDRV mounts on DIN rail and utilizes cable connections and, if needed,
Ethernet switches or hubs to communicate to the AC drive.
The functions of the interface are as follows:
• process input signals from the AC drive.
• format these signals to conform to the Ethernet standard.
• transmit converted signals to the control system.
• receive and translate output signals from the control system.
• sends the output signals to the drive.
The control function is NOT performed by the interface. The control function is
performed by one of the control systems mentioned above. The I/O mapping
function is performed by an H2(4)-ERM module (purchased separately). The
H2(4)-ERM module is configured with the ERM Workbench Utility which is part
of the DirectSOFT PLC programming software.

Communication Ports
Two comm ports are provided to make the connection from a GS Series AC drive
(Serial port) to an Ethernet device or network (Ethernet port).
DIP Switches
The DIP Switches are used to set the Module ID for the GS-EDRV card.
LED Indicators
STATUS Indicator
The green STATUS LED is steady ON when the GS-EDRV is connected to a GS
Series AC drive and communication has been established.
LINK
The green LINK LED is steady ON when the GS-EDRV is correctly connected to an
active device on the network. The LINK LED verifies that the proper cables are
connected, and the card is functioning correctly. If a mismatch with the 10BaseT
connections occurs this LED will not be illuminated.
ACTIVE
The green ACTIVE LED flashes to indicate that the card sees data travelling on the
network. If any network device is sending or receiving data, the ACTIVE LED will
be illuminated. In idle mode (no network traffic) this LED is OFF. During heavy
communication loads this LED will be steady ON.
ERROR Indicator
If the GS-EDRV’s red Error (ERROR) indicator is flashing or steady ON, a fatal
error has occurred. The error may be in the card itself, or a network problem may
be causing this symptom. The ERROR indication can be caused by a faulty
ground, an electrical spike or other types of electrical disturbances. Cycle power
to the system to attempt clearing the error.
RTS
The green RTS LED indicates the GS-EDRV is ready to send information to the AC
drive.
TXD
The green TXD LED flashes to indicate that the card sees data traveling to the AC
drive. During heavy communication loads, this LED will be steady ON.
RXD
The green RXD LED flashes to indicate that the card sees data traveling from the
AC drive. During heavy communication loads this LED will be steady ON.

Setting the GS-EDRV Address
Each GS-EDRV must have an identification (ID) or address in order to be
recognized on the network, and each ID must be unique.
Setting Module ID with DIP Switches
You can use the DIP switch to set the ID to a number from one to sixty-three. Do
not use ID “0” for communication.
If the DIP switch is set to a number greater than 0, the software tools are
disabled from setting the ID. Again, the software tools will only allow changes
to the ID if the DIP switch setting is 0 (zero, all switches OFF).
The GS-EDRV contains eight individual DIP switches, but only six of these are
active. You will find that the switches on the printed circuit board are labeled 0
(zero) through 7. The numbers on the printed circuit board indicate the power of
2 represented by each individual switch. For example, switch 0 represents 20 (or
1), switch 1 is 21 (or 2), switch 2 is 22 (or 4), and so on.
The ID equals the sum of the binary values of the slide switches set in the ON
position. For example, if you set slide switches 1, 2, and 3 to the ON position,
the ID will be 14. This is found by adding 8+4+2=14. The maximum value you
can set on the DIP switch is 32+16+8+4+2+1=63. This is achieved by setting
switches 0 through 5 to the ON position.

GS-EDRV Network Connections
10Base-T Connections
The GS-EDRV Ethernet port has an eight-pin modular jack that accepts RJ45
connector plugs. UTP (Unshielded Twisted-Pair) cable is rated according to its
data-carrying ability (bandwidth) and is given a “category” number. We strongly
recommend using a category 5 cable for all Ethernet 10Base-T connections. For
convenient and reliable networking, we recommend that you purchase
commercially manufactured cables (cables with connectors already attached).
To connect an GS-EDRV (or PC) to a hub, switch, or repeater, use a patch cable
(sometimes called a straight-through cable). The cable used to connect a PC or
an H2(4)-ERM directly to an GS-EDRV or to connect two hubs is referred to as a
crossover cable.

GS-EDRV100 Overview
The GS-EDRV100 provides a low cost, high-performance 10/100Mbps Ethernet
link between a control system and a GS Series AC Drive. The control system can
be any of the following:
• DL205 CPU, DL405 CPU, or a WinPLC, with the appropriate Ethernet Remote
Master module (H2-ERM or H4-ERM).
• A Do-more CPU with an onboard Ethernet port.
• A Productivity3000 CPU using the onboard Ethernet port.
• A PC using a custom device driver that was developed using our Ethernet SDK.
• A PC running KEPDirect EBC or OPC Server.
• Any independent I/O controller with a Modbus TCP/IP driver.
The GS-EDRV100 has an encapsulated compact DIN rail mounted design
allowing for minimal space requirements. With the appropriate cable connections
and, if needed, Ethernet switches or hubs, the GS-EDRV100 will allow you to
communicate with your AC drive over qualified Ethernet networks.
The functions of the interface are as follows:
• process input signals from the AC drive.
• format these signals to conform to the Ethernet standard.
• transmit converted signals to the control system.
• receive and translate output signals from the control system.
• sends the output signals to the drive.
The control function is NOT performed by the interface. The control function is
performed by one of the control systems mentioned above. The I/O mapping
function is performed by an H2(4)-ERM module (purchased separately). The
H2(4)-ERM module is configured with the ERM Workbench Utility which is part
of the DirectSOFT PLC programming software.
Operation
Operation of the GS-EDRV100 is divided up into two communication networks:
1. Communication from the GS-EDRV100 to the drive.
2. Communication from a control device ( PLC, PC, etc..) to the GS-EDRV100
GS-EDRV100 to AC Drive
The GS-EDRV100 will constantly try to read information from the variable
frequency drive. It reads all the parameters from the drive in blocks, so even if
you are only interested in one parameter the GS-EDRV100 has to read all the
parameters over the RS 485 network before that one parameter gets updated
again. The network baud rate defaults to 19200 so this can take some time
(typically around 600ms). This time can be affected by write commands from the
control device. For instance if you try to write information to the drive every 100
ms this could actually slow down the time it takes the GS-EDRV100 to read the
data from the drive as it will interrupt the read process between the GS-EDRV100
and the variable frequency drive. Increasing the rate of the read commands from
GS Series AC Drive Ethernet Interface User Manual 11
GS-EDRV(100) Ethernet Interface
3rd Ed, Rev B 10/2017
the control device will NOT speed up the time it takes for the GS-EDRV100 to
read data from the drive. The only thing that will happen is the control device will
read the same data more often.
Control Device to GS-EDRV100
Communication between the control device and the GS-EDRV100 is for reading
and writing data to the GS-EDRV100 so that the GS-EDRV100 can then write the
data to the variable frequency drive. The GS-EDRV100 can be thought of as the
gateway to the variable frequency drive in that it holds all the information read
from the variable frequency drive that the control device wants to read and writes
all the information from the control device to the variable frequency drive when it
is asked to do so by the control device. This network is ethernet and much faster
than serial, so it can read the data being held in the GS-EDRV100 many times
before the data in the GS-EDRV100 gets updated information from the variable
frequency drive.
Adding a GS-EDRV100 may not necessarily speed up your update performance. If
you are only controlling 1 or 2 drives it may be faster to control them directly on
RS-485 communications if your control device has that capability. However if you
are controlling many drives using the GS-EDRV100 would increase performance
since the Ethernet Protocol can allow for concurrent requests to multiple
GS-EDRV100s simultaneously versus serial which could only send one request at
a time.

For convenient and reliable networking, we recommend that you purchase
commercially manufactured cables (cables with connectors already attached).
To connect an GS-EDRV100 (or PC) to a hub, switch, or repeater, use a patch
cable (sometimes called a straight-through cable). The cable used to connect a
PC or an H2(4)-ERM directly to an GS-EDRV100 or to connect two hubs is
referred to as a crossover cable.

GS-EDRV(100) Ethernet Interface
GS Series AC Drive Ethernet Interface User Manual
18 3rd Ed, Rev B 10/2017
GS-EDRV(100) to GS Series AC Drive Connection
A serial connection cable (2ft. in length) is provided with the GS-EDRV(100) to make
an RS-485 connection with a GS Series AC Drive.
Setting the GS Series AC Drive Parameters
The following parameters need to be set in the GS Series AC Drive in order to
operate properly with the GS-EDRV(100) interface card.
P3.00: 03 or 04 – Operation Determined by RS232C/RS485 interface. Keypad
STOP is enabled (03) or disabled (04).
P4.00: 05 – Frequency determined by RS232/RS485 communication interface
P9.00: 01 – Must be set to 1 in order for the EDRV to communicate to the GS drive
NOTE:
P9.01 will be automatically changed to a value of 2 (19200 baud) by the EDRV, and
it cannot be changed to anything else.
P9.02 will be automatically changed to a value of 5 (Modbus RTU mode <8 data
bits, odd parity, 1 stop bit>) by the EDRV, and it cannot be changed to anything else
The previous list of parameter settings is the minimum required to communicate with a
GS Series AC Drive through a GS-EDRV(100) interface card. There may be other
parameters that need to be set to meet the needs of your application.
RS485
RS232
SW3 SW2
Switches SW2 and SW3 on the drive
must be set to RS485 for an RS-485
connection (GS2 Series Only).
When using the GS2 Series AC Drive , DIP Switch 2 and 3 (SW2 and SW3) on the
drive must be set to RS485.

GS-EDRV(100) to ERM Module Connection
The GS-EDRV(100) interface card can be added to any H2(4)-ERM module using
the ERM Workbench Utility. For more details on selecting and configuring slaves
for the ERM module, see Chapter 4 of the H24-ERM-M.
Reserved PLC Memory for the GS-EDRV(100)
Once the GS-EDRV(100) is added the ERM module, 16 WORD inputs and 11
WORD outputs are mapped back to the PLC. The assigned PLC addresses are
shown in the ERM Workbench Utility.
16 Input WORDS
11 Output WORDS
GS-EDRV(100) Ethernet Interface
GS Series AC Drive Ethernet Interface User Manual
20 3rd Ed, Rev B 10/2017
Reading/Writing From/To the Drive
The control function is NOT performed by the interface. The control function is
performed by the control system. The I/O mapping function is performed by an H2(4)-
ERM module (purchased separately). The H2(4)-ERM module is configured with the
ERM Workbench Utility which is part of the DirectSOFT PLC programming software.
Input/Output Word Map
The Input and Output WORDS for the GS-EDRV(100) are mapped to specific
parameters and functions in the GS Series AC Drives. The Word Map tables on
the following pages show the Input and Output WORDS and their functions.
Using the Input/Output Words
Output Words 10 and 11 are used in conjunction with Input Words 15 and 16 to
Read/Write AC drive parameters that are not mapped to other Input and Output
Words. By using Output Words 10 and 11 with Input Words 14 and 15, you
have the ability to read/write most AC drive parameters.
P9.29 is the only Communication Parameter (P9.xx range) that can be written to using
the Read/Write Input/Output Words (IW 15 & 16; OW 10 & 11). However, these
Input/Output Words can be used to read values from all of the drive Communication
Parameters (P9.xx range).

Built-in Web Server
The GS-EDRV(100) interface card has a built-in Web Server that allows you to
access AC drive data with your favorite Web browser. In order to access the
internal Web Server, you must first assign an IP address to the GS-EDRV(100)
card. The IP address can be assigned by using the NetEdit utility. You can then
access the GS-EDRV(100) card by typing the IP address into your Web browser.
Example
If the IP address of your GS-EDRV100 is 192.168.36.2, just enter
http://192.168.36.2 into the address field of your browser and press the Enter
key.
The browser will then access the built-in Web Server as seen below. The
available parameter groups are shown with links to the parameter options.
