3.2 Additional documentation
For information on how to connect MOVIDRIVE®/ MOVITRAC®B easily and effectively
to the PROFINET IO fieldbus system, you should request the following additional publi-
cations about fieldbus technology:
•'MOVIDRIVE
®Fieldbus Unit Profile' manual
•MOVITRAC
®B / MOVIDRIVE®B system manual
• Manuals on safe disconnection for MOVITRAC®B
• Manuals on safe disconnection for MOVIDRIVE®B
Apart from describing the fieldbus parameters and the corresponding coding, the
MOVIDRIVE®fieldbus unit profile manual and the MOVITRAC®B system manual pro-
vide examples to illustrate various control concepts and possible applications.
The MOVIDRIVE®fieldbus unit profile manual provides a list of all the drive inverter pa-
rameters that can be read and written via the different communication interfaces such
as system bus, RS485 and via the field bus interface.
3.3 Characteristics
With the DFS21B PROFINET IO with PROFIsafe option and its powerful universal field-
bus interface, the MOVIDRIVE®MDX61B drive inverter and the MOVITRAC®B fre-
quency inverter allow for a connection to higher-level automation systems via
PROFINET IO.
3.3.1 MOVIDRIVE®B, MOVITRAC®B and PROFINET
The behavior of the inverter which forms the basis of PROFINET operation, the so-
called unit profile, is independent of any particular fieldbus and is therefore a uniform
feature. This allows the user to develop fieldbus-independent drive applications. This
makes it much easier to change to other bus systems, such as DeviceNet (option DFD).

3Characteristics
Introduction
3.3.2 Access to all information
MOVIDRIVE®MDX61B and MOVITRAC®B offer digital access to all drive parameters
and functions via the PROFINET interface. The drive inverter is controlled via fast, cyclic
process data. Via this process data channel, you can enter setpoints such as the set-
point speed, ramp generator time for acceleration / deceleration, etc. as well as trigger
various drive functions such as enable, control inhibit, normal 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.
3.3.3 Monitoring functions
Using a fieldbus system requires additional monitoring functions for the drive technolo-
gy, for example, time monitoring of the fieldbus (fieldbus timeout) or rapid stop concepts.
You can, for example, adapt the monitoring functions of MOVIDRIVE®/ MOVITRAC®
specifically to your application. You can determine, for instance, which of the drive in-
verter’s error responses should be triggered in the event of a bus error. A rapid stop
makes sense 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
(such as with a conveyor belt). As the range of functions for the control terminals is also
guaranteed in fieldbus mode, you can continue to implement rapid stop concepts using
the terminals of the drive inverter, irrespective of the fieldbus used.
3.3.4 Diagnostics
The MOVIDRIVE®drive inverter and the MOVITRAC®B frequency inverter offer you
numerous diagnostics options for startup and service. You can, for instance, use the
fieldbus monitor integrated in MOVITOOLS®MotionStudio to control setpoint values
sent from the higher-level controller as well as the actual values. The integrated Web
server allows you to access the diagnostic values using a standard browser.
3.3.5 Fieldbus monitor
Furthermore, you are supplied with a variety of additional information about the status
of the fieldbus interface. The fieldbus monitor function in conjunction with the
MOVITOOLS®MotionStudio PC software offers you an easy-to-use diagnostic tool for
setting all drive parameters (including the fieldbus parameters) and for displaying the
fieldbus and device status information in detail.

Safety concept for PROFIsafe fieldbus interfaces
Integrated Safety Technology
4 Integrated Safety Technology
4.1 Safety concept for PROFIsafe fieldbus interfaces
• Within the DFS.. PROFIsafe interface, PROFIsafe fieldbus interfaces are equipped
with an integrated safety-oriented electronics components with a failsafe output
(F-DO). The safety concept of this subassembly is based on the fact that there is a
safe state for all safety-oriented process values. For the DFS.. PROFIsafe interface,
this is the value "0" for the F-DO output.
• The following requirements are fulfilled by means of a 2-channel redundant system
structure of the safety component with suitable monitoring mechanisms:
• SIL3 according to EN 61508
• Category 4 according to EN 954-1
• Performance level e according to EN ISO 13849-1
When the system detects a fault, the system responds by reverting to a safe status.
This makes the safety function available in the form of a failsafe input connected to
a higher-level safety control via the PROFIsafe communication. The safe output on
the safety component of the DFS interface is neither evaluated locally nor processed
logically.
• The safe output F-DO can be used to disable the 24 V input "Safe stop" at X17 of the
MOVIDRIVE®/ MOVITRAC®inverter and in this way safely disconnects the drive.
Refer to the safety concept described in the following for
MOVIDRIVE®/MOVITRAC
®inverters as well as all safety notes, requirements and
installation instructions in this manual.
WARNING
The safety function of MOVIDRIVE®B/MOVITRAC
®B is only permitted for ap-
plications up to category 3 according to EN 954-1.

4Safety concept for MOVIDRIVE® and MOVITRAC®
Integrated Safety Technology
4.2 Safety concept for MOVIDRIVE®and MOVITRAC®
• In case of danger, any potential risk related to a machine must be eliminated as
quickly as possible. Standstill with restart prevention is generally the safe condition
for preventing dangerous movements.
• The MOVIDRIVE®MDX60B/61B and MOVITRAC®B drive inverters are character-
ized by the optional connection of an external failsafe, approved emergency stop re-
lay (according to safety category 3, EN 954-1). The safety relay disconnects all active
elements (disconnection of the safety-relevant 24 V power supply of the output stage
control) that generate the pulse trains to the power output stage (IGBT) when a con-
nected control device (E-STOP button with latching function) is activated.
• Disconnecting the 24 V at the positive and negative poles ensures that the supply
voltages required for operating the inverter and consequently for generating a rotat-
ing field of pulse patterns (which allow the generation of a rotating field) are safely
interrupted. Automatic restart is prevented in this way.
• Instead of galvanic separation of the drive from the power supply by means of relays
or switches, the disconnection of the 24 V supply described here safely prevents the
control of the power semiconductors in the drive inverter. This process disconnects
the rotating field generation for the respective motor. The individual motor cannot de-
velop any torque in this state even though the line voltage is still present.
• The requirements for the safety relay are clearly defined in the following sections and
must be strictly observed.
4.2.1 Limitations
Using a suitable external circuit via a safety relay with
–Approval for at least safety category 3
–Disconnection for at least safety category 3
Allows for operating the MOVIDRIVE®MDX60B/61B and MOVITRAC®B invert-
ers with safe disconnection according to stop category 0 or 1 (to EN 60204-1)
and ensures protection against restart according to safety category 3 (to
EN 954-1).
WARNING
•If the DC 24 V link voltage is safely disconnected at the positive pole only, no
test pulses must be applied to this pole in disconnected condition.
•The safety concept is only suitable for performing mechanical work on driv-
en system/machine components.
•A system/machine-specific risk analysis must be carried out by the sys-
tem/machine manufacturer and taken into account for the use of the
MOVIDRIVE®B/MOVITRAC
®B inverter.
•When the 24 V voltage supply is disconnected, mains supply voltage is still
present on the drive inverter’s DC link.
•If work is carried out on the electrical section of the drive system, the supply
voltage must be disconnected using an external maintenance switch.

Safety Conditions
5 Safety Conditions
5.1 Installation requirements
5.1.1 F-DO connection
• Only connect cables with a core cross section of a minimum of 0.25 mm2(AWG23)
up to a maximum 1 mm2(AWG18) to the safety-related binary output F-DO (X31:1,
X31:2) of the DFS21B option. Clamping without conductor end sleeves is possible in
accordance with IEC 60999.
• The maximum current load of the F-DO safety-related binary output is DC 1 A.
• The safety-related binary output is 2-pole, designed as P-M switch, and controlled
via PROFIsafe®by a higher-level safety control.
• An actuator must generally be connected with the safe output F-DO with a 2-pole
connection between the P switch output and the M switch output (F-DO_P and
F-DO_M).
• It is not permitted to make a 1-pole connection between F-DO_P and the GND refer-
ence potential as doing so would cause an error as soon as the output is controlled.
• Internal testing of the safe output is cyclical. However, when decoupling takes place,
the test pulses at the connection terminals are not visible and need not be taken into
account during operation.
5.1.2 DC 24 V voltage supply
The 24 V supply voltage(s) of the DFS21B and all stations connected to the fieldbus
must be designed as safety extra-low voltage. The voltage must lie within the limits de-
fined in the technical data. In addition, the following voltage values must not be exceed-
ed if a fault occurs (according to EN 60950): Max. DC 60 V, max. DC 120 V for 200 ms.

6Installing the DFS21B option card in MOVITRAC® B
Assembly and Installation Notes
Please note:
• Use a 2x2 core twisted pair and shielded copper cable (data transmission cable with
braided copper shield). Connect the shield flatly on both sides of the electronics
shield clamp of MOVITRAC®B. Also connect the ends of the shield to GND. The ca-
ble must meet the following specifications:
– Cable cross section 0.25 mm2(AWG18) ... 0.75 mm2(AWG23)
– Line resistance 120 Ωat 1 MHz
– Capacitance per unit length ≤40 pF/m 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 kBaud: 160 m
– 500 kBaud: 80 m
– 1000 kBaud: 40 m
• 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
DFS21B gateway must always be connected either at the beginning or the end of the
system bus connection and feature a permanently installed terminating resistor.
INFORMATION
• There must not be any potential displacement between the units connected with
the SBus. Take suitable measures to avoid potential displacement, such as con-
necting the unit ground connectors using a separate cable.
• Point-to-point wiring is not permitted.
