1) As the center of gravity distance x increases, the maximum permitted weight of
the attached motor
R_max
must be reduced linearly. If this center of gravity distance
x is reduced, the maximum permitted weight F
R_max
cannot be increased.

AM adapter with AM../RS backstop
Check the direction of rotation of the drive prior to assembly or startup. In case of a
wrong direction of rotation, contact SEW
‑
EURODRIVE.
The backstop is maintenance-free in operation. Backstops have a minimum lift-off
speed depending on the size (see following table).
NOTICE
If the speed is below the minimum lift-off speed of the drive, the backstop is subject
to wear and heats up.
Possible damage to property.
• In nominal operation the lift-off speed of the drive must not drop below the speci-
fied minimum.
• During startup or braking, the lift-off speed of the drive may drop below the mini-
mum levels.
