Safety Notes
2 Safety Notes
2.1 Bus systems
A bus system makes it possible to adapt frequency inverters to the particulars of the ma-
chinery within wide limits. As with all bus systems, there is a danger of invisible, external
(as far as the inverter is concerned) modifications to the parameters which give rise to
changes in the unit behavior. This may result in unexpected, though not uncontrolled,
system behavior.
2.2 Safety functions
MOVIDRIVE®B and MOVITRAC®B inverters may not perform any safety functions
without higher-level safety systems. Use higher-level safety systems to ensure protec-
tion of equipment and personnel. For safety applications, ensure that the information in
the publication "Functional safety for MOVITRAC®B" is observed.
2.3 Hoist applications
MOVIDRIVE®B and the MOVITRAC®B are not designed for use as a safety device in
hoist applications.. Use monitoring systems or mechanical protection devices as safety
equipment to avoid possible damage to property or injury to people.
2.4 Disposal
Observe the applicable national regulations.
Dispose of the following materials separately in accordance with the country-specific
regulations in force, as:
• Electronics scrap
• Plastics
• Sheet metal

General information
Introduction
3 Introduction
3.1 General information
3.1.1 Content of this manual
This user manual illustrates:
• The installation of the DFE24B EtherCAT®option card in the MOVIDRIVE®MDX61B
drive inverter.
• The use of the DFE24B EtherCAT®option card in the MOVITRAC®B frequency in-
verter and in the UOH11B gateway housing.
• The startup of the MOVIDRIVE®B on the EtherCAT®fieldbus system.
• The startup of the MOVITRAC®B on the EtherCAT®gateway.
• The configuration of the EtherCAT®master via XML files.
• The operation of MOVITOOLS®MotionStudio via EtherCAT®.
3.1.2 Additional documentation
For information on how to connect MOVIDRIVE®B simply and effectively to the
EtherCAT®fieldbus system, you should request the following documentation on fieldbus
technology in addition to this user manual for the DFE24B EtherCAT®option:
• Manual "MOVIDRIVE®B Communication and Fieldbus Unit Profile"
•"MOVIDRIVE
®B" system manual
Apart from describing the fieldbus parameters and the corresponding coding, the
"MOVIDRIVE®B Communication and Fieldbus Unit Profile" manual and the
MOVIDRIVE®B system manual provide examples to illustrate the different control con-
cepts and possible applications.
3.2 Characteristics
3.2.1 MOVIDRIVE®B, MOVITRAC®B and EtherCAT®
The unit behavior of the inverter which forms the basis of EtherCAT®operation is re-
ferred to as the unit profile. It is independent of any particular fieldbus and is therefore a
uniform feature. This feature allows the user to develop fieldbus-independent drive ap-
plications. This makes it much easier to change to other bus systems, such as Devi-
ceNet (DFD option).
3.2.2 Access to all information
MOVIDRIVE®MDX61B and MOVITRAC®B offer digital access to all drive parameters
and functions via the EtherCAT®communication interface. The inverter is controlled via
fast, cyclic process data. You can use this process data channel to enter setpoints (e.g.
setpoint speed, ramp generator time for acceleration/deceleration, etc.) and to trigger
various drive functions such as enable, controller inhibit, normal stop, rapid stop, etc. At
the same time you can also use this channel to read back actual values from the in-
verter, such as actual speed, current, unit status, error number or reference signals.
3.2.3 Cyclic data exchange via EtherCAT®
Process data is usually exchanged cyclically between the EtherCAT®master and the
MOVIDRIVE®B and MOVITRAC®B inverters. The cycle time is specified during the
configuration of the EtherCAT®master.

10 Manual – Fieldbus Interface DFE24B EtherCAT®
3Characteristics
Introduction
3.2.4 Acyclic data exchange via EtherCAT®
Acyclic READ/WRITE services are introduced in line with the EtherCAT®specification.
They are transmitted during normal cyclical operation along with the messages without
affecting the performance of the process data communication via EtherCAT®.
Read and write access to the drive parameters is made possible via SDO (Service Data
Objects), which are implemented according to CoE (CAN application protocol over
EtherCAT®) or VoE services (Vendor-specific over EtherCAT®).
This parameter data exchange enables you to implement applications in which all the
important drive parameters are stored in the higher-level programmable controller, so
that there is no need to make parameter settings manually on the drive inverter itself.
3.2.5 Configuration of the EtherCAT®communication option
The EtherCAT®communication option is designed so that all fieldbus-specific settings
are made during startup of the EtherCAT®system. This means the frequency inverter
can be integrated into the EtherCAT®environment and switched on quickly.
3.2.6 Monitoring functions
Using a fieldbus system requires additional monitoring functions for the drive technol-
ogy, for example, time monitoring of the fieldbus (fieldbus timeout) or rapid stop con-
cepts. You can, for example, adapt the monitoring functions of MOVIDRIVE®B/
MOVITRAC®B specifically to your application. You can determine, for instance, which
of the drive inverter's error responses should be triggered in the event of a bus error. For
many applications, a rapid stop would be the preferred response, but you can also set
other error responses. As the functions of the control terminals are still active in fieldbus
operation, you can still implement fieldbus-independent emergency stop concepts via
the drive inverter terminals.
3.2.7 Diagnostics
MOVIDRIVE®B and MOVITRAC®B provide numerous diagnostics 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.

4Installing the DFE24B option card in MOVITRAC®B
Assembly and Installation Notes
Please note:
• Use a 2×2-core twisted pair and shielded copper cable (data transmission cable with
braided copper shield). Connect the shield on both sides to the electronics shield
clamp of the MOVITRAC®B over a large area. Additionally for a 2-core cable, con-
nect the shield ends to the GND. The cable must meet the following specifications:
– Cable cross section 0.25 mm2(AWG18) – 0.75 mm2(AWG18)
– Cable resistance 120 Ωat 1 MHz
– Capacitance per unit length ≤40 pF/m (12 pF/ft) at 1 kHz
Suitable cables are CAN or DeviceNet cables.
• The permitted total cable length depends on the baud rate setting of the SBus:
– 250 kBd: 160 m (528 ft)
– 500 kBd: 80 m (264 ft)
– 1000 kBd: 40 m (132 ft)
• Connect the system bus terminating resistor (S1 = ON) at the end of the system bus
connection. Switch off the terminating resistor on the other units (S1 = OFF). The
DFE24B gateway must always be connected either at the beginning or the end of the
system bus connection and feature a permanently installed terminating resistor.

Pin assignment X30 IN / X31 OUT
Assembly and Installation Notes
4.5 Pin assignment X30 IN / X31 OUT
Use prefabricated, shielded RJ45 plug connectors to IEC11801 edition 2.0, category 5.
4.5.1 DFE24B – EtherCAT®connection
Option DFE24B is equipped with RJ45 two connectors for a linear bus structure. The
EtherCAT®master is connected (if necessary, via additional EtherCAT®slaves) to X30
IN (RJ45) with a shielded, twisted-pair cable. Additional EtherCAT®units are then con-
nected via X31 OUT (RJ45).
4.6 Shielding and routing bus cables
Only use shielded cables and connection elements that also meet the requirements of
category 5, class D according to IEC 11801, edition 2.0.
Correct shielding of the bus cable attenuates electrical interference that can occur in in-
dustrial environments. The following measures ensure the best possible shielding:
• Manually tighten the mounting screws on the connectors, modules, and equipotential
bonding conductors.
• Use only connectors with a metal housing or a metalized housing.
• Connect the shielding in the connector over a wide surface area.
• Apply the shielding of the bus cable on both ends.
• Route signal and bus cables in separate cable ducts. Do not route them parallel to
power cables (motor leads).
• Use metallic, grounded cable racks in industrial environments.
• Route the signal cable and the corresponding equipotential bonding close to each
other using the shortest possible route.
• Avoid using plug connectors to extend bus cables.

4Bus termination
Assembly and Installation Notes
• Route the bus cables closely along existing grounding surfaces.
4.7 Bus termination
Bus termination (e.g. with bus terminating resistors) is not necessary. If no slave is con-
nected to an EtherCAT®device, it recognizes this immediately.
4.8 Setting the station address
EtherCAT®devices from SEW-EURODRIVE do not have an address that can be set on
the unit. The units are detected by their position in the bus structure and are assigned
an address by the EtherCAT®master. The addresses can be displayed, for example,
using the DBG60B keypad (parameter P093).
4.9 DFE24B operating displays
There are two LEDs on the DFE24B EtherCAT®option card that display the current sta-
tus of the DFE24B option and the EtherCAT®system.
INFORMATION
In case of fluctuations in the ground 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 in accordance with relevant VDE reg-
ulations in such a case.
