Functional safety
Motors from SEW‑EURODRIVE are optionally available with functionally safe motor
options. These are designed for implementing safety functions.
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 for unique identification
of an available functionally safe motor option via the motor nameplate.

bination of safety encoder and safety brake is available at the motor. If an FS logo is
available, adhere to the information specified in the corresponding documentation.
If the drive bears the FS logo on the nameplate, adhere to the information in the fol-
lowing documentation:
