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/gearmotor with
safety-rated encoder in terms of compliance with the functional safety regulations for
encoders. Safety-rated connection elements are sealed to highlight the delivery state.
There are 2 options for performing work on the encoder or motor during which these
sealed screw connections must be opened:
•
Ask the SEW‑EURODRIVE Service to perform this work.
•
If you perform any work on safety-rated encoders yourself, note that disassembly
and assembly work on the safety-rated encoder may only be performed by quali-
fied personnel. All work on the safety-rated encoder and its mechanical coupling
are performed at your own risk, and the responsibility for the safety-rated encoder
and the liability for functional safety shifts to the operator.
