invisible, external (as far as the inverter is concerned) modifications to the parameters
which give rise to changes in the inverter’s behavior. This may result in unexpected (not
uncontrolled) system behavior.

MOVIDRIVE® and
INTERBUS
This user manual describes how to install the INTERBUS DFI11B option card in the
MOVIDRIVE
INTERBUS fieldbus system.
It also contains an explanation of all settings on the fieldbus option card and connection
variants with INTERBUS in the form of small startup examples.
For a simple and effective connection of MOVIDRIVE® to the INTERBUS fieldbus
system, you should request the following publications from SEW-EURODRIVE about
the fieldbus technology in addition to this manual:
•MOVIDRIVE
•MOVIDRIVE
The manual for the MOVIDRIVE
and their coding. It also explains the whole range of control concepts and application
options in the form of small examples.
The parameter list is a list of all drive inverter parameters that can be read and written
via various communication interfaces such as RS-485, SBus and even the fieldbus
interface.
The MOVIDRIVE® drive inverter together with the DFI11B option and its highperformance universal fieldbus interface enable the connection to master
programmable controllers via the open and standardized INTERBUS fieldbus system.

Drive parameters
READ/WRITE
The performance of the inverter (also referred to as the unit profile) that forms the basis
for INTERBUS operation, is fieldbus-independent and, therefore, uniform. This allows
the user to develop fieldbus-independent drive applications. This makes it much easier
to change to other bus systems, such as PROFIBUS (DFP 21B option) or DeviceNet
(DFD 21B option).
MOVIDRIVE® offers digital access to all drive parameters and functions via the
INTERBUS interface. The drive inverter is controlled via the fast, cyclical process data.
This process data channel offers the opportunity to initiate various drive functions such
as enable, controller inhibit, normal stop, rapid stop, and to specify setpoint values such
as setpoint speed, integrator time for acceleration/ramp down.
At the same time you can also use this channel to read back actual values from the drive
inverter, such as actual speed, current, unit status, fault number or reference signals.
While the process data exchange generally occurs cyclically, the drive parameters can
be read or written only acyclically via the READ and WRITE services. This parameter
data exchange enables you to implement applications in which all the important drive
parameters are stored in the master programmable controller, so that there is no need
to make manual parameter settings on the drive inverter itself.

Introduction
Startup
Monitoring
functions
Diagnostics
Generally, the INTERBUS DFI11B option card has been designed so that all
INTERBUS-specific settings, such as process data length and baud rate can be made
using the hardware switch on the option card. This manual setting means the drive
inverter can be integrated into the INTERBUS system and switched on quickly.
The parameter setting process can be performed automatically by the higher-level
INTERBUS master (parameter download). This forward-looking variant shortens the
system startup time and simplifies the documentation of your application program
because all the important drive parameters can now be stored directly in your control
program.
The use of a fieldbus system requires additional drive system monitoring such as time
monitoring of the fieldbus (fieldbus timeout) or even special emergency stop concepts.
The MOVIDRIVE
®
monitoring functions can be customized to your application. You can
determine, for instance, which of the drive inverter’s fault responses should be triggered
in the event of a bus error. A rapid stop is useful for many applications, although this can
also be achieved by 'freezing' the last setpoint values so the drive continues operating
with the most recently valid setpoint values (for example, conveyor belt). As the
functions of the control terminals are still active in fieldbus operation, you can still
implement fieldbus-independent emergency stop concepts via the terminals of the drive
inverter.
The MOVIDRIVE® drive inverter offers numerous diagnostic options for startup and
service.
For example, you can use the integrated fieldbus monitor to control both setpoint values
sent from the higher-level controller as well as the actual values. The MOVITOOLS
software package offers a convenient diagnostic option that allows for a detailed display
of fieldbus and device state information in addition to the settings of all drive parameters
(including fieldbus parameters).

Assembly / Installation Instructions
Pin assignment
Connection to the INTERBUS network is realized using a 9-pin sub D coupling for the
incoming remote bus and a 9-pin sub D plug for the outgoing remote bus according to
IEC 61158. The following figures show the connection assignment of the 9-pole Sub D
coupling/plug for the incoming and outgoing remote bus as well as the signal wire colors
of the bus cable used for the INTERBUS.

As a rule, the DFI11B option is connected to the INTERBUS system using the 2-wire
remote bus with a 6-core shielded cable with twisted signal wire pairs.
Manual – MOVIDRIVE® MDX61B INTERBUS DFI11B Fieldbus Interface
Assembly / Installation Instructions
The 2-wire remote bus chiefly comprises an RS-485 data out channel (signal wires "DO"
and "/DO") and the RS-485 data in channel (signal wires "DI" and "/DI").
3.4 Shielding and routing bus cables
The INTERBUS interface DFI11B supports RS-485 transmission technology and requires the cable type A to IEC 61158 specified as the physical medium for INTERBUS.
This cable must be a 6-core shielded and twisted pair cable.
Correct shielding of the bus cable attenuates electrical interference that may occur in
industrial environments. The following measures ensure the best possible shielding:
• Tighten the mounting screws on the connectors, modules and equipotential bonding
conductors by hand.
• Only use connectors with a metal housing or a metallized housing.
• Connect the shielding in the connector with the greatest possible surface area.
• Attach the shielding of the bus line on both sides.
• Do not route signal and bus cables parallel to power cables (motor leads). They must
be routed in separate cable ducts.
• Use metallic, grounded cable racks in industrial environments.
• Route the signal cable and the corresponding equipotential bonding in close proximity using the shortest way possible.
• Avoid using plug connectors to extend bus cables.
• Route the bus cables closely along existing grounding surfaces.
Shielding and routing bus cables

In case of fluctuations in the earth potential, a compensating current may flow via the
bilaterally connected shield that is also connected to the protective earth (PE). Make
sure you supply adequate equipotential bonding according to relevant VDE regulations
in such a case.
3.5 Setting the DIP switches
The six DIP switches S1 to S6 on the front side of the option are used for setting the
process data length, the PCP length and for selecting the baud rate.

Assembly / Installation Instructions
Setting the DIP switches
Note
De-energize the drive inverter (mains and 24 V backup supply) every time before you
change the DIP switch settings. The settings of DIP switches S1-1 to S1-5 only become
effective during initialization of the drive inverter.
The drive inverter signals the "Microprocessor not ready" ID code (38 hex) if the DIP
switch settings are incorrect.
Setting the baud
rate
Setting the process data and
PCP length
The baud rate is selected using DIP switch S1-6. The selected baud rate takes effect
immediately and might therefore interrupt an existing data communication of the Interbus.
Up to six INTERBUS data words can be exchanged between the INTERBUS interface
and the DFI11B. These data words can be divided between the process data channel
and the PCP channel using DIP switches S1-1 to S1-5. Because of the restriction to six
data words, some settings cannot be reproduced on the Interbus.
The DFI11 signals the "Microprocessor not ready" ID code (38hex) if the setting is incorrect. The incorrect setting is indicated by the red TR LED. The following figure shows
the peripheral conditions for setting the process data and PCP lengths. The following
