Safety notes Preliminary information Safety notes Preliminary information The following general safety notes serve the purpose of preventing injury to persons and damage to property. They primarily apply to the use of products described in this documentation. If you use additional components, also observe the relevant warning and safety notes.
Safety notes Designated use 2.2.1 Safety brakes • The safety brakes described in this documentation are intended for use with DR.., DRN.., DRU.., DR2.., EDR.., and EDRN.. motors. It is not permitted to mount them on other motors. • When using an AC motor in combination with a BE.. safety brake, the safety brake may be used only as a holding brake.
Safety notes Inspection/maintenance Inspection/maintenance The users can perform work themselves on a drive with functionally safe motor op- tions (can be identified by the FS logo on the motor nameplate). Any work on the safety encoder and/or the safety brake is carried out at your own risk. The user is responsible and liable for the proper performance of the work described in the corresponding documentation.
Functional safety (FS) Functionally safe motor options Functional safety (FS) Functionally safe motor options Drives from SEW‑EURODRIVE are also optionally available with functionally safe mo- tor 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.
Functional safety (FS) FS mark 3.1.2 Safety brakes 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 following certificate is available for the described safety brakes: • Certificate of TÜV NORD Systems GmbH & Co. KG A copy of the TÜV certificate can be obtained from SEW-EURODRIVE. Addendum to the Operating Instructions – DR.., DRN.., DRU.., DR2.., EDR.., EDRN.. AC Motors...
Functional safety (FS) Safety functions of the safety brake Safety functions of the safety brake The implementation of a safety function with brakes requires that the brake be applied on request. The safety function is activated when the brake is applied. The brake coil has to be de-energized and the energy stored in the brake coil reduced.
Functional safety (FS) Brake test Brake test In applications with brakes, the braking torque represents an important criterion for the functional and performance capability of the brake. If the braking torque is reduced or lost, the functionality of the application, the safety of the machine, and/or personal safety can be limited.
Functional safety (FS) Motor combinations Motor combinations 3.8.1 Safety brake Motor combinations with BE.. brake Different brake sizes and braking torque steps are available for the various motor series. The following tables show the possible combinations of motor and brakes as well as the available braking torque steps: (E)DR..

Functional safety (FS) Motor combinations Braking torque graduations Depending on the brake requirements, various braking torque graduations are avail- able to suit different brake sizes. The following table shows the available graduations: Brake (M BE03 BE05 BE11 BE20 Bmax (3.4 Nm) (5 Nm) (10 Nm) (20 Nm)
Functional safety (FS) Acceptance Acceptance 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 is reached for each implemented safety function. To validate the safety integrity level you can use the "SISTEMA"...

Mechanical installation General information Mechanical installation General information INFORMATION Note that greases and oils must not be allowed on the mechanical connections of the safety components during assembly or operation. Manual brake release If the manual brake release was ordered, the manual brake release is installed and set at the factory.
Electrical installation Temperature sensor /TF Electrical installation Temperature sensor /TF If you use a safety brake, you must also use and evaluate the temperature sensor /TF. INFORMATION If several motors with safety brake are operated with one frequency inverter (multi- motor operation), an external switching device for monitoring the temperature sensor /TF is necessary.
Inspection/maintenance Inspection and maintenance intervals Inspection/maintenance Inspection and maintenance intervals 7.1.1 Safety brake Inspect and maintain the safety brake in accordance with the configured inspection and maintenance intervals or every 0.5 to 2 years, depending on the operating condi- tions. When using the diagnostic unit /DUE, the wear output of the evaluation unit will show that brake maintenance is required.
Inspection/maintenance Preliminary work for motor and brake maintenance Type of work Work permitted? Comments Retrofit of manual brake If required, contact release /HR SEW‑EURODRIVE. Replacement of manual Observe the permitted position of the brake release /HR manual brake release. Retrofit of diagnostic Requires replacement of the safety unit /DUE brake.
