1. GENERAL
Vacon frequency converters can be connected to the Profibus DP by using a Fieldbus board. The
converter can then be controlled, monitored and programmed from the Host system.

The used I/O can also be extended with the Fieldbus board:
• 4 digital inputs (standard signals)
• 4 digital outputs (2 standard signal)
• 1 relay output (standard signal)
• Thermistor input (can be directly connected to the motor thermistors for overtemperature trip)
• Encoder input

The Profibus fieldbus board can be installed inside the frequency converter as instructed in this manual.
Note that the installation procedure is different for CX/CXL (board CX202OPT) and CXS frequency
converters (CX210OPT).

The control connections are isolated from the mains potential and the I/O ground is connected to the
frame of the device via a 1 MΩ resistor and 4.7 nF capacitor*. The control I/O ground can also be
connected directly to the frame by changing the position of the jumper X9 (GND ON/OFF) to ON-
position. Digital inputs are also isolated from the I/O ground.

NOTE ! Internal components and circuit boards (except for the isolated I/O terminals) are at mains
potential when the frequency converter is connected to the mains. This voltage is extremely
dangerous and may cause death or severe injury if you come into contact with it.

The control I/O terminals are isolated from the mains potential, but the I/O:s (if jumper X9 is in
OFF-position) may have dangerous voltage connected even if the power is off on the
frequency converter.

* Default value = X9 is GND OFF- position)

2.2 Profibus cable

Profibus devices are connected in a bus structure. Up to 32 stations (master or slaves) can be
connected in one segment. The bus is terminated by an active bus terminator at the beginning and end
of each segment (see figure 2-1). To ensure error-free operation, both bus terminations must always be
powered. When more than 32 stations are used, repeaters (line amplifiers) must be used to connect the
individual bus segments.
The maximum cable length depends on the transmission speed and cable type (see table 2-4). The
specified cable length can be increased by the use of repeaters. The use of more than 3 repeaters in
series is not recommended.

3. PROFIBUS DP
3.1 General

PROFIBUS is a vendor-independent, open fieldbus standard for a wide range of applications in

manufacturing, process and building automation. Vendor independence and openness are guaranteed
by the PROFIBUS standard EN 50 170. With PROFIBUS, devices of different manufacturers can
communicate without special interface adjustments. PROFIBUS can be used for both high-speed time
critical data transmission and extensive complex communication tasks. The PROFIBUS family consists
of three compatible versions.

PROFIBUS-DP
Optimized for high speed and inexpensive hookup, this PROFIBUS version is designed
especially for communication between automation control systems and distributed I/O at the
device level. PROFIBUS-DP can be used to replace parallel signal transmission with 24 V or 0
to 20 mA.

PROFIBUS-PA
PROFIBUS-PA is designed especially for process automation. It permits sensors and actuators
to be connected on one common bus line even in intrinsically-safe areas. PROFIBUS-PA
permits data communication and power over the bus using a 2-wire technology according to the
international standard IEC 1158-2.

PROFIBUS-FMS
PROFIBUS-FMS is the general-purpose solution for communication tasks at the cell level.
Powerful FMS services open up a wide range of applications and provide great flexibility.
PROFIBUS-FMS can also be used for extensive and complex communication tasks.

PROFIBUS specifies the technical and functional characteristics of a serial fieldbus system with which
decentralized digital controllers can be networked together from the field level to the cell level.
PROFIBUS distinguishes between master devices and slave devices.

Master devices determine the data communication on the bus. A master can send messages without an
external request when it holds the bus access rights (the token). Masters are also called active stations
in the PROFIBUS protocol.

Slave devices are peripheral devices. Typical slave devices include input/output devices, valves, drives
and measuring transmitters. They do not have bus access rights and they can only acknowledge
received messages or send messages to the master when requested to do so. Slaves are also called
passive stations.

3.2 Profiles

The PROFIBUS-DP protocol defines how user data are to be transmitted between the stations over the
bus. User data are not evaluated by the PROFIBUS-DP transmission protocol. The meaning is
specified in the profiles. In addition, the profiles specify how PROFIBUS-DP is to be used in the
application area. The following PROFIBUS-DP profile is used in VACON CX Profibus fieldbus board.

Variable-Speed Drive Profile (3.071)

Leading manufacturers of drive technology have jointly defined the PROFIDRIVE profile. The profile
specifies how the drives are to be parameterized and how the setpoints and actual values are to be
transmitted. This enables drives from different vendors to be exchanged. The profile contains necessary
specifications for speed control and positioning. It specifies the basic drive functions while leaving
sufficient freedom for application-specific expansions and further developments. The profile describes
the mapping of the application functions for DP or FMS.

4. INSTALLATION
NOTE! These instructions apply if you have received the Profibus board for Vacon CX or CXL
drives (CX202OPT) as an accessory. Otherwise the board has already been installed for you at
the factory.
Instructions for the installation of Profibus option board for Vacon CXS drives (CX210OPT) you
will find in Appendix C.

Before doing any commissioning, carefully read the safety instructions in the "Vacon CX/CXL/CXS
frequency converter, User's manual" chapter “SAFETY”. Check that you have received all the Fieldbus
board parts: Fieldbus board, plastic board, power cable (black terminal), data cable (blue terminal) and
earthing screw.
Fieldbus board can be installed in the place reserved for an option board inside the frequency converter
(see figure 4-1).

Remove the control panel and jumper X4 from the control board (1).
A
Connect the power cable to control board terminal X5 (2) and the data cable to terminal X14
B (3). The power cable can also be connected to terminal X6, if the power cable from the
power board is connected to terminal X5.

Bend the data cable into an "S-curve" as far as possible from the power board transformer
C (4) before you place the plastic board above the control board.

Remove the protection foil of the plastic board and place the plastic board on the control
D board, remember the right position of the plastic board (5).

Install the Fieldbus board above the plastic board by the larger holes and push it downward
E so that the narrow part of the hole in the board fits the cut on the sleeve. Check that the
installation is stable. If you have difficulties placing the plastic board and the Fieldbus board,
slightly bend the regulator A4 (6) and capacitor C59 (7) of the control board.

Connect the power cable to terminal X6 of the Fieldbus board (8) and the data cable to the
F terminal X14 (9).

Install the jumper which you removed from the terminal X4 of the control board, on the
G terminal X9 of the Fieldbus board (10) in ON or OFF position.

If the package includes the cable cover (11), fasten it into position as shown in figure 4-1.
H
Install the earthing screw (12).
I
After this install the control panel and connect the needed control signals.
J
If you use a 5 V encoder input, install the jumpers on terminal X15 (see figure 5-1) of the
K Fieldbus board (one jumper on the two upper pins and the other on the two lower).

7. PROFIBUS-VACON CX INTERFACE
Features of the Profibus-Vacon CX interface:
• Direct control of Vacon CX ( e.g. Run, Stop, Direction, Speed reference, Fault reset)
• Full access to all Vacon CX parameters
• Monitor Vacon CX status (e.g. Output frequency, Output current, Fault code ..)

7.1 General

Data transfer between Profibus DP master and slave takes place via the Input/Output data field. The
master writes to slave’s Output data and the slave answers by sending the contents of its Input data to
the master. The contents of Input /Output data is defined in a device profile, PROFIDRIVE is the device
profile for frequency converters.

The Vacon CX frequency converter can be controlled by Profibus DP master using PPO-types defined
in PROFIDRIVE (see next chapter). When fieldbus has been selected as the frequency converter’s
active control place, the frequency converter’s operation can be controlled from the Profibus DP master.
Whether or not the active control place is fieldbus, the frequency converter can be monitored and its
parameters can be set by the Profibus DP master.

7.2 PPO-types

0 Not Ready (initial) READY
1 Not Ready READY
2 DISABLE ENABLE
3 NO FAULT FAULT ACTIVE
4 STOP 2 OFF STOP 2 ON
5 STOP 3 OFF STOP 3 ON
6 START ENABLE START DISABLE

7.3.3 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 “control word” parameter. The “status word”
parameter indicates the current status of the state machine. The modes INIT, STOP, RUN and FAULT
(see figure 7-1) correspond to the actual mode of the Frequency converter.

DISABLE (Bit6=1) is one value of the “status word”.

Bit0=0 is one value of the “control word”.

7.3.5 Actual Value

Actual value of the motor. The range is -10000... 10000, 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)

7.3.6 PD1-PD4
The master can read the frequency converter’s actual values using process data variables. There are
four process data variables and each of them can be selected to show one of the monitoring page
variables or active fault code. Selection can be done in two different ways:

By master: Parameter 916.1 PD1

916.2 PD2
916.3 PD3
916.4 PD4

By control panel: Parameter Process Data 1 PD1

Process Data 2 PD2
Process Data 3 PD3
Process Data 4 PD4

Set the number of the variable to be monitored (see table 7-1) or number 99 for the active fault code to
the value of the parameter.
