FS marking
SEW-EURODRIVE labels a functionally safe motor option on 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 makes it possible to uniquely identify an available functional safety motor option via the motor nameplate.
Make sure you observe any present FS logo on the nameplate and its meaning according to the following table:
FS logo
| Available functionally safe motor option | ||
|---|---|---|---|
Decentralized | Safety brake | Safety encoders | |
| ✔ | – | – |
| – | ✔ | – |
| – | – | ✔ |
| ✔ | – | ✔ |
| – | ✔ | ✔ |
✔ | The motor option is functionally safe. |
– | The motor option is not available. |
If the FS logo is present on the motor nameplate, e.g. with the code "FS 11", the motor includes a combination of safety encoder and safety brake. Drives can also be equipped with 2 encoders, e.g. a built-in encoder and an add-on encoder. In such cases, the FS logo for the safety encoder always relates to the add-on encoder. If an FS logo is available, adhere to the information specified in the corresponding documentation.
If the FS logo with the code "FS 0X" is present on the motor nameplate, a special design related to functional safety is installed at the motor.
Observe the information concerning the special design in the documentation.
