Common questions
What does the 9910004 drive stop do?
It screws into the motor output shaft to keep the drive from coming off. Somfy supplies the screw with a black composite stop and includes instructions, and lists the part as the Drive Stop and Screw.
Which motors does it fit?
Somfy lists 95 compatible 50-series motors, including Sonesse 506S2 and 510S2, Sonesse ULTRA 506A2, Altus RTS, Oximo RTS, Orea RTS, Maestria RTS, T5 and DMI5 models. Store examples include the Maestria 525A2 RTS (1134083) and the DMI5 50Nm 12rpm 120V (2000776).
Which drives does it pair with?
It works with the drives that mount on those motor shafts, such as the Octagonal LT50 60mm Drive Wheel (9751001) and the 60mm Round LT50/60 Aluminum Drive Wheel (9012950). Fit the drive first, then secure it with the stop.
When should I add a drive stop?
Add one whenever you fit or replace a drive on a compatible 50-series motor. The stop keeps the drive seated on the output shaft, and the instructions Somfy includes show how to fit it.
Is this a genuine Somfy part, and what warranty applies?
Yes. This is genuine Somfy part 9910004, which the Somfy catalog names the LT50 Stop Wheel and T5 Drive Stop. Somfy backs it with a 5-year warranty.
