Page 13: Scope Of Delivery And Unit Structure
SEW-EURODRIVE drives can be supplied with safety-rated components on request. SEW-EURODRIVE indicates such an integration by the FS mark and a number on the nameplate. The number is a code that indicates which components in the motor are safety-related. -
Page 14: Nameplate
The FS logo on the nameplate is based on the combination of safety-related compo- nents that is installed, see code table above. Functional Safety – Synchronous Servomotors CMP40-112, CMPZ71-100... -

When a BY brake is used, the working air gap must be measured at regular inter- vals, which are specified in the "Synchronous Servomotors" operating instructions in chapter "Inspection/Maintenance". A working air gap that exceeds the permitted maximum value can cause encoder errors or destroy the encoder. Functional Safety – Synchronous Servomotors CMP40-112, CMPZ71-100... -
Page 21: Functional Safety
Certain demands on the mechanical coupling of the encoder system to the motor must be met so that the encoder can be used for safety-relevant tasks. SEW-EURODRIVE assumes responsibility for the delivered motor with safety-rated en- coder in terms of compliance with the functional safety regulations. Safety-relevant con- nection elements are sealed in order to be able to ensure that the delivery condition is not changed, see following figures. - Page 22 Inspection/maintenance Functional safety CMPZ71/80/100 CMP71/80/100 CMPZ71/80/100 /BP CMP112 CMPZ71/80/100 /BY AK1H CMP112 /BY [1] Sealed screw connections of the encoder Functional Safety – Synchronous Servomotors CMP40-112, CMPZ71-100...
- Page 23 SEW-EURODRIVE to inform the respective customers/operators in the event of product defects. Consistent retraceability by SEW-EURODRIVE is no longer ensured if you perform work on safety-rated encoder system, e.g. if you replace or retrofit encoders. This is why we strongly suggest that you establish your own retraceability procedure and/or to support the SEW-EURODRIVE measures.
