1. GENERAL
Vacon frequency converters can be connected to Interbus-S fieldbus by using fieldbus board. The
converter can be then controlled, monitored and programmed from the Host system. Fieldbus board
follows connection profile 21 for frequency converters defined by DRIVECOM user’s group. This
guarantees that interfacing of the Vacon frequency converter to the Interbus-S fieldbus happens
according to the standardized parameters and functions. Then the commissioning of the frequency
converter speed up and control of the frequency converter facilitated. Vacon Fieldbus board is a remote
bus device.
The used I/O can be also extended by the Fieldbus board:
• 4 digital inputs (standard signals)
• 4 digital outputs (standard signals)
• Termistor input (can be directly connected into the motor termistors for over temperature trip)
• Encoder input
Fieldbus board can be installed into the existing option board place inside the frequency converter.
The control connections are isolated from the mains potential and I/O ground is connected to the frame
of the device via an 1 MΩ resistor and 4.7 nF capacitor*. The control I/O ground can be connected also
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.
Internal components and circuit boards (except the isolated I/O terminals) are at mains
potential when the Vacon CX/CXL is connected to the mains. This voltage is extremely
dangerous and may cause death or severe injury if you come in 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 Vacon
CX/CXL.
* Default value (X9 is GND OFF- position)

1. INTERBUS-S
Interbus-S is fast sensore/actuator fieldbus. Through Interbus-S fieldbus both individual I/O-device and
intelligent actuator can be controlled, such as frequency converter. Due to topology Interbus-S is able to
fast, under 10 ms, response times.
Interbus-S is from it’s topology a ring, where is one Host system. As a Host system can function for
example a programmable logic, industrial design PC or process station of the automation system.
Remote bus cable which begins from Host System combines the Bus terminals of the field. The long
displacements in the field are implemented by using Remote bus. If Bus terminal in the field does not
include repeat function, it will be connected to Interbus-S fieldbus by using Local bus. Local bus situated
in the field is local, switch cabinet’s internal bus, which is however a part of the Interbus-S circle. Vacon
equipped with Fieldbus board is Remote bus device.

Information can be deliver two ways to the device, which is in the Interbus-S field. The Process channel
is used for the fast information delivery. With the support of this channel can be for example speed
reference of the frequency converter placed and get back the actual speed information. Slower, but
more information included parameter information delivery PCP channel is used (Peripheral
Communication Protocol), when message construction according to DRIVECOM Profile 21 is used.

4. INSTALLATION
Before doing any commissioning actions read carefully safety instructions from the "User's manual
CX/CXL/CXS frequency converter"- manual chapter 2. Check that you have got 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 into the existing option board place inside the frequency converter (see
figure 4-1).
Remove the control panel and the jumper X4 from the control board (1).
A
Install the power cable into the control board X5 -terminal (2) and data cable to the X14 -
B
terminal (3). Power cable can also be installed into the X6 -terminal, if the power cable from
the power board is connected into the X5 -terminal.
Bend the data cable to the "S-curve" as far as possible from the power board transformer
C
(4) before you install the plastic board into the control board.
Remove the protection foil of the plastic board and install the plastic board into the control
D
board, remember the right position of the plastic board (5).
Install the Fieldbus board into the plastic board from the larger holes and "push" it into the
E
right position in the narrow position of the screws . Check that the Fieldbus board is installed
stable. If you have difficulties to place the plastic board and Fieldbus board, bend slightly the
regulator A4 (6) and capasitor C59 (7) of the control board.
Install the power cable to the X6 -terminal of the Fieldbus board (8)and data cable to the
F
X14 -terminal (9).
Install the jumper which you remove from the X4 -terminal of the control board, into the X9 -
G
terminal of the Fieldbus board (10) ON or OFF position.
If the packet includes the cable cover (11), install that into position shown in figure 1.
H
Install the earthing screw (12).
I
After this install the control panel and connect the needed control signals.
J
If use 5 V encoder input, install the jumper to the X7-terminal (see Chapter 5, figure 1) of the
K
Fieldbus board.
