Introduction
2 Introduction
Contents of this
manual
This user manual describes how to install the DeviceNet DFD11B option card in the
MOVIDRIVE®MDX61B drive inverter and how to start up MOVIDRIVE®with the
DeviceNet fieldbus system.
Besides explaining all settings on the fieldbus option card, this document also covers
the various DeviceNet connection variants in the form of brief startup examples.
Additional
documentation
For a simple and effective connection of MOVIDRIVE®to the DeviceNet fieldbus
system, you should request the following publications from SEW-EURODRIVE about
the fieldbus technology in addition to this manual:
•MOVIDRIVE
®Fieldbus Unit Profile manual
•MOVIDRIVE
®MDX60/61B system manual
The manual for the MOVIDRIVE®fieldbus unit profile describes the fieldbus parameters
and their coding, as well as explaining the whole range of control concepts and applica-
tion options in the form of brief 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.
MOVIDRIVE®and
DeviceNet
The MOVIDRIVE®MDX61B drive inverter together with the DFD11B option and its high-
performance universal fieldbus interface enable the connection to higher-level automa-
tion systems via the open and standardized DeviceNet fieldbus system.
Unit profile The performance of the inverter, referred to as the unit profile, that forms the basis for
the DeviceNet 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 INTERBUS
(DFI11B option).
Drive parameters MOVIDRIVE®offers you direct access to all drive parameters and functions via the
DeviceNet interface. The drive inverter is controlled via the fast, cyclical process data.
Via this process data channel, you have the opportunity of entering setpoints such as
the setpoint speed, ramp generator time for acceleration/deceleration, etc. as well as
triggering various drive functions such as enable, control inhibit, standard stop, rapid
stop, etc.
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, error number or reference signals.
Polled I/O and Bit
Strobe I/O
The parameters of the inverter are set exclusively using Explicit Messages , whereas the
process data exchange is replicated on the DeviceNet services
Polled I/O and
Bit-Strobe I/O . This parameter data exchange enables you to implement applications in
which all the important drive parameters are stored in the master programmable control-
ler, so that there is no need to make manual parameter settings on the drive inverter it-
self.

2Introduction
Startup Every DFD11B DeviceNet option card is designed so that the fieldbus-specific MAC-ID
and baud rate settings are made using hardware switches on the option card. This man-
ual setting means the drive inverter can be integrated into the DeviceNet system and
switched on quickly.
The parameter setting process can be performed in a completely automated process by
the DeviceNet 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.
Monitoring
functions
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®MDX61B monitoring functions can be customized to your applica-
tion. You can determine, for instance, which of the drive inverter error responses should
be triggered in the event of a bus error. A rapid stop is a good idea for many applications,
although this can also be achieved by "freezing" the last setpoints so the drive continues
operating with the most recently valid setpoints (for example, conveyor belt). As the
functions of the control terminals are still active in fieldbus operation, you can still imple-
ment fieldbus-independent emergency stop concepts via the terminals of the drive
inverter.
Diagnostics The MOVIDRIVE®MDX61B drive inverter offers numerous diagnostic options for start-
up and service.
For example, you can use the integrated fieldbus monitor to check both the setpoints
sent by the master control and 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 field-
bus parameters).

3Connection and terminal assignment
Assembly / Installation Instructions
Pin assignment The assignment of connecting terminals is described in the DeviceNet specification
(Volume I, Appendix A).
The DFD11B option card is opto-decoupled on the driver side in accordance with the
DeviceNet specification (Volume I, Chapter 9). This means the CAN bus driver must be
powered with 24 V voltage via the bus cable. The cable to be used is also described in
the DeviceNet specification (Volume I, Appendix B). The connection must be made
according to the color code specified in the following table.
Shielding and
routing of bus
cables
The DeviceNet interface supports RS-485 communications protocol and requires cable
type A specified for DeviceNet in accordance with EN 50170 as shielded, twisted-pair
cable for the physical connection.
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.
• Attach the shielding of the bus line over a large surface 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 proxim-
ity using the shortest way possible.
• Avoid using plug connectors to extend bus cables.
• Route the bus cables closely along existing grounding surfaces.
Bus termination In order to avoid disruptions in the bus system due to reflections, each DeviceNet seg-
ment must be terminated with 120 Ωbus terminating resistors at the first and last phys-
ical station. Connect the bus terminating resistor between connections 2 and 4 of the
bus plug.

Project Planning and Startup
4 Project Planning and Startup
This section describes how to configure and start up the MOVIDRIVE®MDX61B drive
inverter with the DFD11B option.
4.1 Startup of the drive inverter
You can immediately configure the MOVIDRIVE®drive inverter after installation of the
DFD11B option and setting of the baud rate and MAC-ID via the fieldbus system without
additional manual settings. In this way, you can download all drive parameters from the
master programmable controller directly via DeviceNet after the power is switched on.
However, to control the drive inverter via the DeviceNet system, you must first switch
the drive inverter to the control signal source and setpoint source = FIELDBUS. The
FIELDBUS setting means the inverter parameters are set for control and setpoint trans-
fer from the fieldbus. The drive inverter then responds to the process output data sent
by the master programmable controller.
Activation of the control signal source/setpoint source FIELDBUS is signaled to the
higher-level controller using the "Fieldbus mode active" bit in the status word. For safety
reasons, the drive inverter must also be enabled at the terminals for control via the field-
bus system. Consequently, the terminals must be wired or programmed in such a way
that the inverter is enabled via the input terminals.
The simplest way of enabling the drive inverter at the terminals is to connect the DIØØ
(function /CONTROLLER INHIBIT) input terminal to a +24 V signal and to program input
terminals DIØ1 ... DIØ5 to NO FUNCTION. The following illustration shows by way of
example how to startup the MOVIDRIVE®drive inverter with fieldbus interface.

Procedure for
startup of the
MOVIDRIVE®
MDX61B
1. Enable the power output stage at the terminals.
Connect the input terminal DIØØ / X13.1 (function /CONTROLLER INHIBIT) to a
+24 V signal (for example, using a device jumper).
2. Turn on the external 24 V voltage supply (not mains voltage supply!).
You can now configure the drive inverter.
3. Setpoint source = FIELDBUS / control signal source = FIELDBUS.
Set the setpoint source and control signal source parameters to FIELDBUS to control
the drive inverter via a fieldbus.
4. Input terminals DIØ1 ... DIØ5 = NO FUNCTION.
Set the function of the input terminals to NO FUNCTION.

words (6 bytes) are processed in the inverter and three process input data words are
sent to the control.
No process data are processed or sent back if the control transmits more than ten pro-
cess output data words.
Three process data words are processed and three process input data words are sent
from the inverter to the control if the control transmits three process output data words.
The set process data length influences the process data lengths of both the polled I/O
and the bit-strobe I/O messages.
The process data length of the bit-strobe I/O messages can include up to four process
data words. If the value for the process data length set via DIP switches is less than four,
it will be accepted. If the value set via DIP switches is greater than four, the process data
length will be automatically limited to four.

Process data exchange
Project Planning and Startup
The process output data are stored in the output file of the PLC and the process input
data of the PLC are stored in the input file. In the example above, the output data words
O:3.10, O:3.11 and O:3.12 are copied to process output data words 1, 2 and 3 and pro-
cessed by the inverter. The inverter sends back three process input data words that are
copied into input data words I:3.10, I:3.11 and I:3.12 of the PLC.
Timeout
response with
polled I/O
The timeout is triggered by the DFD11B option. The timeout time must be set by the
master after the connection has been established. The DeviceNet specification refers to
an "expected packet rate" rather than a timeout time in this case. The expected packet
rate is calculated on the basis of the timeout interval using the following formula:
tTimeout_inverter = tTimeout interval_PolledIO = 4 x tExpected_Packet_Rate_PolledIO
The expected packet rate can be set using the connection object class 5, instance 2,
attribute 9. The range of values runs from 0 ms to 65535 ms in 5 ms steps.
The expected packet rate for the polled I/O connection is converted into the timeout
interval and displayed in the device and the timeout interval in parameter P819.
This timeout interval is retained in the device whenever the polled I/O connection is
dropped, and the device switches to timeout status after the timeout interval has
elapsed.
The timeout interval must not be altered in the inverter using MOVITOOLS®or the
DBG60B keypad, because it can only be activated via the bus.
If a timeout occurs for the polled I/O messages, this connection type enters timeout
status. Incoming polled I/O messages are no longer accepted.
The timeout causes the timeout reaction set in the inverter to be carried out.
The timeout can be reset with DeviceNet by means of the reset service of the connection
object (class 0x05, instance 0x02, undetermined attribute), by disconnecting the
connection, by means of the reset service of the identity object (class 0x01, instance
0x01, undetermined attribute) or with the reset bit in the control word.
Bit-strobe I/O Bit-strobe I/O messages are not contained in the SEW fieldbus profile. The messages
represent a DeviceNet-specific process data exchange. The master sends a broadcast
message that is 8 bytes (= 64 bits) long. One bit in this message is assigned to each
station in accordance with its station address. The value of this bit may be 0 or 1, and
thereby trigger two different reactions in the recipient.
If you select a different process data length, you will have the expand the memory to be
managed in the PLC as well. If the process data length is set to 10, you will have to
configure 10 process output data words and 10 process input data words.

Project Planning and Startup
The following table shows the data area of the bit-strobe request telegram which repre-
sents the allocation of stations (= station address) to data bits.
Example: For example, the station with station address (MAC-ID) 16 only processes bit
0 in data byte 2.
In the example above, the bit-strobe I/O message is stored in memory words O:3.10 to
O:3.13. The inverter sends three process input data words to the PLC; these are stored
in the input file in input data words I:3.10 to I:3.12.
Important:
The BIO LED on the front of the DFD11B option can be used for distinguishing between
the timeout triggered by the bit-strobe telegram and a real timeout in the connection. It
remains continuously green if the timeout is triggered by the bit-strobe telegram.
If the BIO LED flashes red, this means there is a timeout in the bit-strobe connection and
no more bit-strobe telegrams are accepted. Each station that has received this bit-strobe
I/O message responds with its current process input data. The length of the process in-
put data corresponds to the process data length for the polled I/O connection. The pro-
cess input data length can be up to four process data.
