Introduction
Vacon NX frequency converters can be connected to Ethernet using an Ethernet fieldbus board OPTCP. The OPTCP can be installed in board slots D or E.
Every appliance connected to an Ethernet network has two identifiers; a MAC address and an IP address. The MAC address (Address format: xx:xx:xx:xx:xx:xx) is unique to the appliance and cannot be changed. The Ethernet board’s MAC address can be found on the sticker attached to the board or by using the Vacon IP tool software NCIPConfig. You can find the software installation at www.vacon.com.
In a local network, IP addresses can be defined by the user as long as all units connected to the network are given the same network portion of the address. For more information about IP addresses, contact your Network Administrator. Overlapping IP addresses cause conflicts between appliances. For more information about setting IP addresses, see Section 3, Installation.
WARNING!
Internal components and circuit boards are at high potential when the
frequency converter is connected to the power source. This voltage is
extremely dangerous and may cause death or severe injury if you come into
contact with it.

INTRODUCTION
Vacon NX frequency converters can be connected to Ethernet using an Ethernet
fieldbus board OPTCP.
The OPTCP can be installed in board slots D or E.
Every appliance connected to an Ethernet network has two identifiers; a MAC

Table 1. Ethernet board technical data
LED indications
Using the “Node Flashing Test” function you can determine to which device you are directly con-nected. For example in Siemens S7, by using the menu command “PLC > Diagnostics/Setting > Node Flashing Test…” you can identify the station connected directly to the PG/PC by the FORCE LED that flashes.
Ethernet
Common-use cases of Ethernet devices are ‘human to machine’ and ‘machine to machine’. Basic features of these two cases are presented in the pictures below.
- Human to machine (Graphical User interface, relatively slow communication) Note! NCDrive can be used in NXS and NXP drives via Ethernet. In NXL drives this is not possible.
- Machine to machine (Industrial environment, fast communication)
Connections and wiring
The Ethernet board supports 10/100Mb speeds in both Full- and Half-duplex
modes. However, using Profinet requires the Full-duplex mode and the
100-megabit speed. The boards must be connected to the Ethernet network with a
Shielded Twisted Pair (STP) CAT-5e cable. Use a so-called crossover cable if
you want to connect the Ethernet option board directly to the master device.
Use only industrial standard components in the network and avoid complex
structures to minimize the length of response time and the amount of incorrect
dispatches.
More information on Ethernet can be found at
www.odva.org.
INSTALLATION
Installing the Ethernet Option Board in a Vacon NX Unit
NOTE MAKE SURE THAT THE FREQUENCY CONVERTER IS SWITCHED OFF BEFORE AN OPTION OR FIELDBUS BOARD IS CHANGED OR ADDED!
NCDrive
NCDrive software can be used with the Ethernet board in NXS and NXP drives.
NOTE! Does not work with NXL
NCDrive software is recommended to be used in LAN (Local Area Network) only.
NOTE! If OPTCI Ethernet Option board is used for NC Tools connection, like
NCDrive, the OPTD3 board can not be used.
NOTE! NCLoad does not work via Ethernet. See NCDrive help for further
information
IP Tool NCIPConfig
To begin using the Vacon Ethernet board, you need to set an IP address. The
factory default IP ad dress is 192.168.0.10. Before connecting the board to
the network, its IP addresses must be set according to the network. For more
information about IP addresses, contact your network administrator.
You need a PC with an Ethernet connection and the NCIPConfig tool installed to
set the Ethernet board’s IP addresses. To install the NCIPConfig tool, start
the installation program from CD or download it from
www.vacon.com website. After starting the installation
program, follow the on-screen instructions.
Once the program is installed successfully, you can launch it by selecting it
in the Windows Start menu. Follow these instructions to set the IP addresses.
Select Help –> Manual if you want more information about the software
features.
-
Step 1. Connect your PC to the Ethernet network with an Ethernet cable. You can also connect the PC directly to the device using a crossover cable. This option may be needed if your PC does not support Automatic crossover function.
-
Step 2. Scan network nodes. Select Configuration –> Scan and wait until the devices connected to the bus in the tree structure are displayed to the left of the screen.
NOTE! Some switches block broadcast messages. In this case, each network node must be scanned separately. -
Step 3. Set names. Select the cell in column ‘Node’ and enter the name of the node.
-
Step 4. Set IP addresses. Change the node’s IP settings according to the network IP settings. The program will report conflicts with a red color in a table cell.
-
Step 5. Send configuration to boards. In the table view, check the boxes for boards whose configuration you want to send and select Configuration, then Configure. Your changes are sent to the network and will be valid immediately.
NOTE! Only A-Z, a-z and 0-9 symbols can be used in the drive name, no special characters, or Scandinavian letters (ä, ö, etc.)! The drive name can be freely formed using the allowed characters.
Update OPTCP Option Board program with the NCIPConfig Tool
In some cases it may be necessary to update the option board’s firmware.
Differing from other Vacon option boards, the Ethernet option board’s firmware
is updated with the NCIPConfig tool.
To start the firmware update, scan the nodes in the network according to the
instructions in section 3.2. Once you can see all nodes in the view, you can
update the new firmware by clicking the VCN packet field in NCIPCONFIG ‘s
table view on the right.
NOTE! The PC’s IP address must be chosen in the same IP address space as the
Ethernet board’s.
After clicking the VCN packet field, a file open window where you can choose a new firmware packet is displayed.
Select the desired packet and click Open.
NOTE!
Do not do a power up cycle after downloading the option board software or
installing a new option board to the drive within 1 minute. This may cause the
option board to go to “Safe Mode”. This situa-tion can only be solved by re-
downloading the software. The Safe Mode triggers a fault code (F54). The Board
slot error F54 may also appear due to a faulty board, a temporary malfunction
of the board or disturbance in the environment.
Configure Option board parameters
These features are available from NCIPConfig tool version 1.6.
In the tree-view, expand the folders until you reach the board parameters.
Slowly double-click the parameter (Comm. Time-out in figure below) and enter
new value. New parameter values are auto-matically sent to the option board
after the modification is complete.
NOTE! If the fieldbus cable is broken at the Ethernet board end or removed, a fieldbus error is im-mediately generated.
Example with Siemens PLC
- Create project
- Insert station
- Double-click hardware to open HW config window.
- Insert rail
- Insert power supply
- Insert CPU
- Change IP address and select subnet by clicking New.
- Click OK
- Click OK
- Now configuration should look like this
- Drag and drop OPTCP to Profinet IO system
- Select communication profile
- Change Optioncard properties
- Verify Device Name.
- Close window.
- Change IO cycle to 16 ms (minimum) or greater.
COMMISSIONING
The Vacon Ethernet board is commissioned with the control keypad by giving values to appropriate parameters in menu M7 (or with NCIPConfig tool, read chapter IP Tool NCIPConfig). Keypad com-missioning is only possible with NXS and NXP series AC drives. AC drives of the NXL series can only be commissioned with the NCIPConfig tool.
Expander board menu (M7)
The Expander board menu makes it possible for the user to see which expander
boards are con-nected to the control board and to reach and edit the
parameters associated with the expander board.
Enter the following menu level (G#) with the Menu button right. At this level,
you can browse trough slots A to E with the Browser buttons to see what
expander boards are connected. On the lowermost line of the display you see
the number of parameter groups associated with the board. If you still press
the Menu button right once you will reach the parameter group level where
there are one group in the Ethernet board case: Parameters. A further press on
the Menu button right takes you to Parameter group.

Table 2. Ethernet parameters
IP Address
IP is divided into 4 parts. (Part = Octet) Default IP Address is 192.168.0.10.
Communication timeout
Defines how much time can pass from the last received message from the Master
Device before fieldbus fault is generated. Communication timeout is disabled
when given the value 0. The commu-nication timeout value can be changed from
the keypad or with NCIPConfig tool (see chapter IP Tool NCIPConfig).
NOTE!
If the fieldbus cable is broken at the Ethernet board end or removed a
fieldbus error is immediately generated.
All Ethernet parameters are saved to the Ethernet board (not to the control
board). If the Ethernet board is replaced by a new one you must re-configure
the new Ethernet board. Option board para-meters can also be saved to the
keypad using the NCIPConfig tool or the NCDrive.
Start-up test
In the AC drive application:
Choose Fieldbus (Bus/Comm) as the active control place (see Vacon NX User’s
Manual, Chapter 7.3.3).
In the Master software:
- Set Control Word value to 0hex.
- Set Control Word value to 47Ehex.
- Set Control Word value to 47Fhex.
- Frequency converter status is RUN.
- Set Reference value to 5000 (=50.00%).
- The Actual value is 5000 and the frequency converter output frequency is 25.00 Hz.
- Set Control Word value to 477hex.
- Frequency converter status is STOP.
PROFINET IO
PROFINET is the Ethernet-based automation standard of PROFIBUS International for the implementation of an integrated and consistent automation solution based on Industrial Ethernet. PROFINET supports the integration of simple distributed field devices and time-critical applications in (switch-ed) Ethernet communication, as well as the integration of component-based distributed automation systems for vertical and horizontal integration of networks.
**Vendor profile
**
In vendor mode there are three PPO types; PPO3,PPO4,PPO6. These PPO types should have same functionality than Vacon NX Profibus. In PPO mode control word and status word goes though state machine.
Control word (Vendor profile)
The Control command for the state machine (see Figure 2) The state machine
describes the device status and the possible control sequence of the frequency
converter.
The control word is composed of 16 bits that have the following meanings:
Table 3.
Bit | Description |
---|---|
Value = 0 | |
0 | STOP 1 (by ramp) |
1 | STOP 2 (by coast) |
2 | STOP 3 (by ramp) |

14 | Fieldbus DIN4=OFF |
15 | Fieldbus DIN5=OFF |
Status word (Vendor profile)
Information about the status of the device and messages is indicated in the
Status word. The Status word is composed of 16 bits that have the following
meanings:
Bit | Description |
---|---|
Value = 0 | |
0 | Not Ready (initial) |
1 | Not Ready |

Table 4.
Comes straight from the frequency converter **Bits of the State Machine
State Machine
The state machine describes the device status and the possible control
sequence of the frequency converter. The state transitions can be generated by
using the “Control word”. The “Status word” indicates the current status of
the state machine. The modes INIT, STOP, RUN and FAULT correspond to the
actual mode of the Frequency converter.
NOTE! Always set CW bit0 to 0 after fault reset before proceeding!
Reference
This is the reference 1 to the frequency converter. Used normally as Speed
reference.
The allowed scaling is –10000…10000. In the application, the value is scaled
in percentage of the fre-quency area between set minimum and maximum
frequency.
- -10000 = 100,00 % (Direction reverse)
- 0 = 0,00 % (Direction forward)
- 10000 = 100,00 % (Direction forward)
Actual value
This is the actual value from the frequency converter. Value between -10000…10000. In the applica-tion, the value is scaled in percentage of frequency area between set minimum and maximum fre-quency.
- -10000 = 100,00 % (Direction reverse)
- 0 = 0,00 % (Direction forward)
- 10000 = 100,00 % (Direction forward)
Process data in
ProcessData Master -> Slave
The Master can write max. 8 additional setting values to the device with the
help of the Process Data. How these setting values are used is totally
dependent on the application in use.
Process data out
ProcessData Slave -> Master
The master can read the frequency converter’s actual values using the process
data variables. Depending on the used application, the contents are either
standard or can be selected with a para-
meter.
Bypass profile
In BYPASS mode there are three types.
Control Word (Bypass profile)
The meanings of the Control Word bits is application-dependent.
Status Word (Bypass profile)
The meanings of the Status Word bits are application-dependent.
Profidrive profile
The PROFIDRIVE profile has been jointly defined by drive manufacturers. The profile specifies aspects of drive parameterization and how the setpoints and actual values should be transmitted. This makes drives in a fieldbus vendor- independent and possible to be replaced by a drive from a different vendor. The profile contains specifications needed for speed control and positioning and it specifies the basic drive functions while leaving sufficient freedom for application-specific expansions and further developments.
Application class 1
The Profinet board supports Application Class 1 of the Profidrive profile
(version 4.1 ). Application Class 1 defines Standard Telegram 1. The standard
telegrams have the following structure:
I/O data num- ber | 1 | 2 |
---|---|---|
Setpoint | STW1 | NSOLL_A |
Actual value | ZSW1 | NIST_A |
Table 5.
STW1
STW1 is the Profidrive profile’s control word. The control word is for
controlling the drive from a fieldbus. It is sent by the fieldbus master to
the drive. The drive switches between its states accord-ing to the bit-coded
instructions on the control word. Because the STW1 and the drive’s own control
words are different the STW1 has to be written to Drive Interface through
state machine. Some of the STW1 bits go straight to Drive Interface.
The STW1 is composed of 16 bits that have the following meanings:
Bits | Description |
---|---|
Value = 0 | |
0 | OFF |
1 | Coast stop (No OFF2 / OFF2) |
2 | Quick stop (No OFF3 / OFF3) |
3 | Disable operation |

a Optional; depends on application
b Depends on application
ZSW1
ZSW1 is the Profidrive profile’s status word. Status word indicates
information about the status of the device. Also messages are indicated in the
Status word. The ZSW1 Status word is composed of 16 bits that have the
following meanings:
Bits | Description |
---|---|
Value = 0 | |
0 | Not ready to switch on |
1 | Not ready to operate |
2 | Operation disabled |
3 | No fault |
4 | Coast stop activated (No OFF2 / OFF2) |
5 | Quick stop activated (No OFF3 / OFF3) |
6 | Switching on not inhibited |

9 | No control requested |
10 | f or n not reached |
11 | Device-specific |
12 | Device-specific |
13 | Device-specific |
14-15 | Device-specific |
NSOLL_A
NSOLL_A is the reference to the drive. It is used normally as Speed reference.
Reference is a 16-bit word containing a sign bit and a 15-bit integer. A
negative reference (indicating reversed direction of rotation) is formed by
calculating the two’s complement from the corresponding positive reference.
The allowed scaling is –10000…10000. In the drive application, the value is
scaled in percentage of the frequency area between set minimum and maximum
frequency.
- -10000 = 100,00 % (Direction reverse)
- 0 = 0, 00 % (Direction forward)
- 10000 = 100,00 % (Direction forward)
NIST_A
NIST_A is the actual value from the frequency converter. It contains values
between -10000…10000. In the application, the value is scaled in percentage of
frequency area between set minimum and maximum frequency.
- -10000 = 100,00 % (Direction reverse)
- 0 = 0, 00 % (Direction forward)
- 10000 = 100,00 % (Direction forward)
State Machine
The state machine describes the device status and the possible control
sequence of the frequency converter. The state transitions can be generated by
using the “Control word”. The “Status word” indicates the current status of
the state machine. The modes INIT, STOP, RUN and FAULT corres-pond to the
actual mode of the Frequency converter
Additional Process data in
ProcessData Master -> Slave
The Master can write max. 8 additional setting values to the device with the
help of the Process Data. How these setting values are used is totally
dependent on the application in use.
Additional Process data out
ProcessData Slave -> Master
The master can read the frequency converter’s actual values using the process
data variables. Depending on the used application, the contents are either
standard or can be selected with a parameter.
Parameter channel
The Parameter channel can be used to access the Drive’s parameters and the PROFIDRIVE’s parameters.

APPENDIX
Process Data OUT (Slave- > Master)
The fieldbus master can read the frequency converter’s actual values using
process data variables. Basic, Standard, Local/Remote, Multi-Step, PID control
and Pump and fan control applications use process data as follows:
Data | Value | Unit | Scale |
---|---|---|---|
Process data OUT 1 | Output Frequency | Hz | 0,01 Hz |
Process data OUT 2 | Motor Speed | rpm | 1 rpm |
Process data OUT 3 | Motor Current | A | 0,1 A |
Process data OUT 4 | Motor Torque | % | 0,1 % |
Process data OUT 5 | Motor Power | % | 0,1 % |
Process data OUT 6 | Motor Voltage | V | 0,1 V |
Process data OUT 7 | DC link voltage | V | 1 V |
Process data OUT 8 | Active Fault Code | – | – |
The Multipurpose application has a selector parameter for every Process Data. The monitoring val-ues and drive parameters can be selected using the ID number (see NX All in One Application Ma-nual, Tables for monitoring values and parameters). Default selections are as in the table above.
Process Data IN (Master - > Slave)
ControlWord, Reference and Process Data are used with All-in One applications
as follows:
