1. GENERAL
Vacon NX frequency converters can be connected to the Profibus DP using a fieldbus board. The con-
verter can then be controlled, monitored and programmed from the Host system.
The Profibus fieldbus board shall be installed in slot E on the control board of the frequency con-
verter.
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.

2.2 Profibus cable
Profibus devices are connected in a bus structure. Up to 32 stations (master or slaves) can be con-
nected 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 2-3 ). The
specified cable length can be increased using the repeaters. The use of more than 3 repeaters in se-
ries is not recommended.

3. PROFIBUS DP
3.1 Introduction
Profibus is a vendor-independent, open fieldbus standard for a wide range of applications in manu-
facturing, 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 com-
munication 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 acknowl-
edge 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 NX Profibus Fieldbus board.
3.2.1 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 neces-
sary specifications for speed control and positioning. It specifies the basic drive functions while leav-
ing sufficient freedom for application-specific expansions and further developments. The profile de-
scribes the mapping of the application functions for DP or FMS.

4. PROFIBUS FIELDBUS BOARD LAYOUT AND CONNECTIONS
Vacon Profibus Fieldbus Board is connected to the fieldbus through either a 5-pin pluggable bus con-
nector (board OPT-C3) or a 9-pin female sub-D-connector (board OPT-C5).
The communication with the control board takes place through the standard Vacon Interface Board
Connector.

4.1.1 Grounding of bus cable shield in OPT-C3
The bus cable shield can be grounded in three different ways:
a) directly to the frequency converter frame
b) to the frame of the frequency converter through an RC filter
c) clamping the cable to the converter frame (recommended)
Note: Normally, the option board has already been installed in slot E of the control board. It is not
necessary to detach the whole board for the grounding of the bus cable shield. Just detach the termi-
nal block.
4.1.1.1 Grounding the bus cable shield directly to the frequency converter frame using jumper X1
1Set jumper X1 in ON position:

2Strip about 5 cm of the Profibus cable as shown in the picture.
Note: Do the same for both bus cables (except for the last device). However, since the
grounding shall be done on one cable only cut off the exposed part of the other grounding
cable.
