Other axes

For axes that are not gravity-loaded, e.g. horizontal drives with a horizontal direction of movement, a comparable recommendation has not been made thus far in the IFA Report or by other institutions. SEW‑EURODRIVE therefore recommends a test torque related to the static holding torque of the brake (M4,100 °C). This corresponds to the maximum static torque that the brake must be able to hold.

The maximum test torque Mtest can be determined based on the nominal braking torque Mbr indicated on the motor nameplate or according to the technical data in the documentation.
