4.13.4 AD../RS – cover with backstop
Check the direction of rotation of the drive prior to assembly or startup. Inform the SEW-
EURODRIVE service in the case of incorrect direction of rotation.
The backstop is maintenance-free in operation, and does not require any further main-
tenance work. Backstops have a minimum lift-off speed depending on the size (see fol-
lowing table).
NOTICE
If the actual speed level is below the minimum lift-off speed level, the backstops are
subject to wear, and the resulting friction causes the temperature to increase.
Possible damage to property
• In rated operation, the lift-off speeds must not drop below the minimum values.
• During startup or braking, the lift-off speeds may drop below the minimum levels.
