2.2 Designated use
• DR.., DRN.., EDR.., EDRN.. motors with functionally safe motor options are inten-
ded for industrial systems.
• When installed in machines, start of the designated operation is prohibited until it is
determined that the machine complies with the local laws and directives. The Ma-
chinery Directive 2006/42/EC is valid for the respective area of application.
• Air-cooled versions are designed for ambient temperatures of -20 °C to +40 °C
and installation altitudes ≤ 1000m above sea level. Any differing specifications on
the nameplate must be observed. The ambient conditions must comply with all the
specifications on the nameplate.
• In order to determine the safety integrity (performance level PL and/or safety integ-
rity level SIL) of a system's safety functions, the system manufacturer must per-
form an overall evaluation. This document contains the product-related specifica-
tions necessary for the evaluation.

to EN60204‑1.
• The safety brake BE.. may only be used on the motor series DR.. and DRN.. at an
ambient temperature of -20°Cto+40 °C.
• The dimensioning of drives with BE.. safety brake considers a maximum of
1000emergency stop braking operations in the life cycle. A minimum pause of 6
minutes must be adhered in between 2 emergency stop braking operations. Pro-
ject planning clearly defines how often the system can perform the emergency
stop braking.
• When dimensioning the BE.. safety brake, observe the valid project planning spe-
cifications of SEW‑EURODRIVE and the resulting application limits. If the applica-
tion requirements or technical properties of the BE.. safety brake change, project
planning and a check of the application limits must be performed again.

3.1 Functionally safe motor options
Drives from SEW‑EURODRIVE are optionally available with functionally safe motor
options. These options are intended for implementation of safety functions in safety-
relevant applications.
SEW‑EURODRIVE assumes responsibility for the delivered drive in terms of compli-
ance of the functionally safe motor options with the functional safety regulations. To
detect deviations from the delivery state, safety-relevant connection elements are
sealed.
3.1.1 Safety encoder
Safety encoders from SEW‑EURODRIVE are characterized by their exceptional reli-
ability as well as electronic and mechanical load capacity.
Safety encoders allow you to increase the safety in your machines by implementing
safety functions regarding speed, direction of rotation, idle state and relative position.
The safety encoder provides the safety-relevant signals in the intelligent interaction of
sensor, control and actuator.
The safety function requires a reliable mechanical connection between encoder and
motor. At SEW‑EURODRIVE, this connection is dimensioned in such a way that fault
exclusion is achieved.
The safety encoders cannot trigger a safe state at the machine autonomously. There-
fore, they have to be monitored in the overall system. The overall system will trigger a
suitable error response, e.g. the safe state, on request.
3.1.2 Safety brake
Safety brakes from SEW‑EURODRIVE are characterized by their exceptional reliabil-
ity as well as electronic and mechanical load capacity.
Safety brakes allow you to increase the safety in your machines by implementing
safety functions for deceleration and stopping. The safety brake represents the safety-
relevant actuator in the intelligent interaction of sensor, control and actuator.
Safety brakes from SEW‑EURODRIVE already consider the following functional safety
requirements according to ENISO 13849, parts 1 and 2:
• Application of basic safety principles
• Application of proven safety principles
• Information on the characteristic safety value B10d
• Common cause failure (CCF)
• Notice of influences and ambient conditions
• Determination of the category (Cat.)
• Retraceability by the unique motor assignment
• Production monitoring with 100% final inspection
• Compliance with normative requirements regarding documentation
The suitability for functional safety as well as compliance with the normative require-
ments is certified by TÜV Nord Systems GmbH&Co.KG. You can rely on the manu-
facturer confirmation (e.g. TÜV certificate) in your safety-related overall evaluation and
considerably reduce efforts for evaluation and documentation of a brake.

The safety brakes cannot trigger a safe state at the machine autonomously. The
brakes have to be supplemented with a suitable brake control and monitored by brake
diagnostics, if necessary. The overall system triggers a suitable error response, e.g.
the safe state, on request.
3.2 FS mark
Motors from SEW‑EURODRIVE are optionally available with functionally safe motor
options. These are designed for implementation of safety functions.
The documentation designates the respective functional safety design explicitly as
safety encoder plus "type designation" or safety brake plus "type designation".
SEW‑EURODRIVE labels a functionally safe motor option at the drive with an FS logo
and a 2-digit number on the motor nameplate. The number is a code that indicates
which components in the drive are safety-related. This allows to uniquely identify an
available functionally safe motor option via the motor nameplate.

3.3 Retraceability
Functionally safe motor options can be retraced by SEW‑EURODRIVE with the motor
serial number and thus have a unique assignment to the motor.
If the SEW‑EURODRIVE service replaces a safety encoder or a safety brake, the re-
traceability is ensured.
If you replace a functionally safe motor option on your own, you revoke this assign-
ment. To continue the assignment, document the replacement yourself.
3.4 Underlying standards
The safety assessment of safe motor options is based on the following standards and
safety classes:
Safety encoder

The following safety functions according to EN61800‑5‑2 regarding speed, direction
of rotation, idle state and relative position can be implemented in functionally safe sys-
tems with the sine/cosine interface of the safety encoders:
• SS1, SS2, SOS, SLS, SDI, SLI, SSR, SLS, SAR, SSM
INFORMATION
For AS7W, AG7W, AS7Y and AG7Y encoders, the absolute interface is not part of
the PL d/SIL 2 approval. The absolute interface may not be solely used for imple-
menting safety functions.
Built-in encoder EI7C FS
The following safety functions according to EN61800‑5‑2 regarding speed and direc-
tion of rotation can be implemented in functionally safe systems with the HTL interface
of the safety encoder:
• SS1, SLS, SDI
3.6.2 Safety functions of the safety brake
The implementation of a safety function with electromechanical brakes requires that
the brake is applied on request. The safety function is activated when the brake is ap-
plied. The brake coil has to be de-energized and the energy stored in the brake coil re-
duced.
By adding a BE.. safety brake into a safe overall system, the following safety functions
can be implemented:
• SBA – Safe Brake Actuation
• SBH – Safe Brake Hold
INFORMATION
Safety functions SBA and SBH are defined by SEW‑EURODRIVE in accordance with
the standard EN61800‑5-2 .
The implementation of the SBA and SBH safety functions additionally require the
safety functions SBC and STO in the overall system. For safety-related requests of
the brake, SBC and STO ensure that the brake applies and that the drive does not
generate a torque against the applied brake.
The SBC and STO safety functions are not part of the brake and have to be addition-
ally implemented in the overall safety system. The performance level (PL) of the SBC
and STO safety functions must at least meet the required performance level (PLr) of
the application.
SEW‑EURODRIVE recommends to stop the drive using the stop category 1 accord-
ing to EN60204‑1 prior to activating the SBC and STO safety functions.

The monitoring of the sine/cosine signals for detecting the safe state is performed by
the follow-up electronics. The follow-up electronics has to check the sine/cosine sig-
nals of the rotary encoder for validity. For safety-related use of the encoders, the fol-
lowing requirements have to be fulfilled by the follow-up electronics:

If the safety encoders are connected with prefabricated encoder cables from
SEW‑EURODRIVE to the follow-up electronics from SEW‑EURODRIVE, these re-
quirements have been met.
3.7.2 Integrated encoders: EI7C FS
Operating the EI7C FS built-in encoder at encoder evaluation units of other manufac-
turers is not permitted. Observe the corresponding manuals. The built-in encoder is in-
tended for operation with functionally safe encoder evaluation units from
SEW‑EURODRIVE, e.g. safety option S12.

Functional safety (FS)
Brake diagnostics
Addendum to the Operating Instructions – DR.., DRN.., EDR.., EDRN.. AC Motors 15
3.8 Brake diagnostics
In applications with brakes, the braking torque represents an important criterion for the
functionality of the brake. In the event of a reduction in or loss of braking torque, the
correct functionality of the application is no longer ensured. As a result, the safety of
the machine and/or even the safety of persons may be decreased. To prevent this
from happening, the brake can optionally be checked using brake diagnostics. Brake
diagnostics provides the user with information about the status and performance cap-
ability of the brake. This allows you to detect potential errors in time and initiate main-
tenance/repair.
Brake diagnostics may be required by standards, particularly in safety-related applica-
tions in accordance with ENISO13849 in which a safety function is implemented us-
ing a brake. The diagnostic coverage level (DCavg) required by standards must be ful-
filled depending on the required Performance Level (PL). The diagnostic coverage is a
key figure of the implemented brake diagnostics.
Brake diagnostics must detect the following possible failures separately for each
brake:
• Brake is not applied.
• Insufficient braking torque.
To prevent faulty diagnostic results, SEW‑EURODRIVE recommends to additionally
diagnose the potential failure "Brake does not release".
Brake diagnostics is not part of the brake and must be implemented within the system.
SEW‑EURODRIVE offers the brake diagnostics solution e.g. as software for the con-
troller of the performance classes advanced/power. Brake diagnostics fulfills the regu-
latory requirements and allows for solutions in up to performance level e (PLe).

3.10 Validation
The system manufacturer has to perform an overall evaluation for determining the
safety of a machine.
The effectiveness of each risk minimization must be checked. It must also be checked
if the required safety integrity (SIL and/or PL) is reached for each implemented safety
function.
